49:1 unun wire lengths49:1 unun wire lengths

Lengths of a half-wave or multiple must be avoided. You can get good loading and low swr on sometimes 2 or 3 bands, but one or more of the bands thatyou want, just will not cooperate with an swr that can be adjusted with the "tuner". 2 0 obj Use with other lengths can potentially damage the transformer depending on power level in use. Experimenting by slightly changing the wire length (+ or-) is encouraged to provide best overall performance. Ham Radio Videos! So a 49:1 impedance transformer is needed to match the 50 ohms of the coax at the feed line. Lowest Band of Operation: 160 meters Highest Band of Operation: 10 meters Additional Information LDG Electronics RU-9:1 Unun Technical specification : Type : 49:1 Unun Frequency : 1.8 MHz - 7.3 MHz Turns ratio: 1:7 Impedance ratio: 1:49 Input Impedance: 50 Output Impedance: 2450 Power Handling (CW/SSB/ Digital Modes) : 2Kw of peak power / DM Modes 500 watts Core Type : 3 x FT240-43 by Fair-rite Co. Wire type: Enamel copper wire 2.0 mm (AWG 12) Assembled and tested. At multiples of half wavelengths of the To DB's point of a single band antenna, this 49:1 transformer is a good choice for a single band matcher. Usually any wire length that is non resonant, like those shown above, will work with the 4:1 ratio. This design is excellent for matching both long and short length wire antennas for multiband use. A success! I've made contact with several folks across North America in my 6 months as an amateur but getting to Europe flipped a switch and I'm afraid this amateur radio thing is going to be addicting. endobj You are using an out of date browser. wire is at least 1/4 wavelength. Figure 2 Schematic of the 9:1 voltage unun . When you're 1/2w long you're around 2k ohms or more where the balun won't under or over xform; as you approach 3/4w your z is going to drop to where a coax match can be made just by soldering the wire to the center conductor sans balun - more or less the principle of the windom and ocf dipole. It's an efficient way to get all the multiples /Length 6 0 R So you have the freq range of interest and the total length of the wire, figuring out wich balun will be a better match for 50ohm coax should be easy. 4 0 obj Building on the original 1:1 design by Dr. Jerry Sevick, this balun has two (2) cores in a stacked Model 49131 - 49:1 - 80-10m EFHW - Up to 1kW, Decrease Quantity of Model 49131 - 49:1 - 80-10m EFHW - Up to 1kW, Increase Quantity of Model 49131 - 49:1 - 80-10m EFHW - Up to 1kW. (The numbers aboveare a great start, thanks to Jack and Mike! endobj here are values for CW portions of the USA First, it is important to understand the difference between the end fed half wave and a random wire (or "long wire") antenna: the random wire is just a piece of wire that is matched to 50 Ohm impedance using an antenna coupler, sometimes adding a 9:1 unun. One is for the top of the box so that it can be hung up. Proudly powered by WordPress endstream endobj startxref the C code, in Matlab or Octave get a plot by simply putting the Generally an EFHW will be in the range of 2,000 to 5,000 ohms at the very end of the dipole when resonant. This design is excellent for matching both long and short length wire antennas for multiband use. Update guys:made the unun,the antenna was extended to about 37m length,and I added a counterpoise which is about 10m.The whole thing is much higher in the air,compared to where it was before. Lengths to avoid are not always the same as /Subtype /Image program or two to do all the dirty work. If the transformer is used with an externaltuner in conjunction with a single wireantenna typically 130-135 feet in length, power should be reduced on those bands that show an SWR above 1.6 to2:5 withoutthe tuner. In other (Note: I am not satisfied with this part of the project, so I will describe it here briefly. This is considered a random wire end fed antenna, not to be confused with a half wave end fed antenna which uses a 49:1 or 64:1 unun and a wire that is a half wave length. Here are the final numbers (in my opinion) in green below that would be good for a long-wire antenna: (You may want to make a note of them), REVISED: 29 35.5 41 58 71 84 107 119 148 203 347 407 423, REVISION NOTE: We had a note from James, KB5YN, pointing out that one of my so-called GOOD numbers was 220 feet. Superior Essex Heavy build polyamideimide. If you would like to use high power up to legal limit with a single end fed wire antenna (not necessarily a half wave) consider using our Model 9135 along with one of the wire lengths shown in the Installation Notes. Weight: 0.380 lbs. Attaching a counterpoise wire to the common point of the auto-transformer provides the antenna radiator something to push against rather than the coax shield. u?X`f0&/Ri;W0Tn_*TX:ug /Length 10 0 R << So those are the numbers above thatwe have to stay as far away from as possible when building a long-wire antenna. .

Privacy Policy rig, often with no feedline, and the other end in the air attached to Our newdesign isperfect for matching both long and short length wire antennas for multiband use. Just a note, if you make one of these yourself, you need to twist together the first two wraps of the 14 winding wire with both wraps of the two winding wire. It is important to use a counterpoise. W3EDP's results in the above referenced We hoisted the free end of the antenna wire approximately 30 feet into a tree. /Im0 Do Many hams have tried till they are blue in the face to install the random wire antenna that works on most; if not all of the HF bands with terrible results. SWR was good after cutting the wire to appropriate length. Each vertical blue line represents an amateur radio band. This will be for an eyehook in order to provide strain relief for the radiator wire. In stock .

I connected it to a 33 wire running from my balcony, through the trees, and ran WSPR overnight to check things out. /Resources << So after much frustration..down it comes and you go on to a totally different type of antenna.all that time just wasted inyour opinion..until now! Continue twisting the entire length of the short wire. Cut the ground wires (free twisted short and long wires) of the unun to the correct size, scrape the enamel insulation off of the free end with a box cutter, and add a ring terminal. When you're antenna (or radial) length's an odd multiple of the operating freq, you may not need a balun or even a transmatch. That's it in a nutshell..or is it? This is the latest and greatest transformer design for End Fed Half Wave (EFHW) antennas. I will also find some sort of heat resistant packing material to help hold the transformer in place. https://elginradio.wordpress.com/2017/10/17/end-fed-half-wave-antennas/. The short piece is for the primary winding of the transformer, and the long piece is for the secondary winding of the transformer. Jack, VE3EED, hopefully has solved a major headache we all have when we attempt to go thru the trial and error and frustration with getting the random wire to work where WE want it to work. If you want all the bands from 3 0 obj 3. He had heard good things about 'Balun Designs' so he recommended you. 1. Box cutter (for scraping enamel off of wire ends), (Helpful) Step drill bit for SO-239 connector, Paracord (for simulating and measuring lengths of windings on toroid), Antenna analyzer for HF frequencies (I use the RigExpert Zoom AA-55), Resistor(s) totaling about 3000 ohms (I used 1K and 2K ohm resistors in series). On our next windy free day, AA1F and . You'll want to have that wire up as high as you can get.. Wait a few minutes for glue to set. The following is a list of materials required to make a 49:1 unun impedance transformer for an end-fed half wave antenna. While these lengths have been shown to work well on many bands, which The goal of the impedance transformer is match the 50 ohm impedance of the feedline (coaxial cable) with the potential 3000 to 4000 ohm impedance expected from an end-fed half wave antenna wire radiator. endobj This homebrew 49:1 impedance transformer is the heart of any EFHW antenna you will build, most of the time. >> and experiment.

This transformer is designed to be used with an end fed half wavelength of wire only. I sent him the link to the 49:1 unit to get his feedback. Well then you need to choose a wire length that is at least 1/4 on 40 meters, and doesn't fall on any of the 1/2 multiples for ALL the bands between 40 to 10 meters While you could certainly calculate the lengths to avoid using the standard formulas, and then make a chart, the section below may be what you are looking for. To summarise the results WRT to reference antenna consisting of 30ft wire vertical fed with auto- In total 29 contacts were made from British Columbia to Texas to Florida in 40 minutes on 20M. Tweak the antenna length if necessary and then maybe adjust the turns ratio again. Wire-Lengths-for-9-1-ununs.pdf Created Date: 12/12/2022 11:20:42 AM . K1S Valentines Are (Almost) Out The Door! Kj8~q7c? . Moving the pot up and down gives a feel for the SWR versus antenna impedance sensitivity. The length of a half wave antenna is calculated using the following formula: L (ft) = 468 / f (freq in mhz). I have used the 49.2 ft (15 Meter) length of wire on vacation with both automatic tuners and an MFJ Model 16010 tuner with good results for 40, 20, 17, and 15 Meter operation. 5 0 obj Swr usually is all over the place and the tuner will just not do it's job. /CropBox [0 0 748 752] are easily converted to half wavelengths by the famous 468/f generally Feeling a bit too lazy to calculate that by hand, however, I wrote a Meet 'Balun One Nine', a small, cost-effective balun. Just add or subtract as needed a little at a time toget the best compromise. An Unun is used to match an unbalanced line to another unbalanced line. 73, x@ stream Here's a list of recommended lengths of wire to use with a 9:1 unun. He knew that in order for the tuner to "see" a fairly low swr to work within it's range,that the antenna had to be NOT A HALF WAVE ON ANY FREQUENCY that we wanted to us, because a half wave will give us a very high impedance and the resultingswr into a 50 ohm transmitter! Theme designed by Papathemes. I say run what you got and don't worry about it. %PDF-1.4 endobj All you need for a random wire antenna is some wire, your tuner, one or more supports up as high as you can get them to string the wire from the supports to the tuner, at least one or two insulatorsand a little time. UNUN 9:1 or 4:1- 3kW ICAS This is is dual 9:1 and 4:1 UNUN used for popular "non-resonant" length END FED wire antennas or verticals like 27 or 43 feet. Drill a hole in the top for an eyehook (to be used to secure the unun to whatever it is you want to hang it from.). Start winding the toroid with the twisted wires at loop #1 (see schematic below). The most common question I get asked is what is the correct length for my End Fed Long Wire Antenna? Built with the same craftsmanship as all our other For those that enjoy endfed antennas but want to run more power, Balun Designs now offers an excellent alternative. BUILD INSTRUCTIONS FOR 49:1 UNUN IMPEDEDENCE TRANSFORMER: WX1MAR and I brought the DIY 49:1 unun with a borrowed antenna radiator wire cut for 20M half-wavelength to Ashland State Park K-2417 in Massachusetts for a Parks-on-the-Air (POTA) activation. Solder a the 100pF capacitor between the center conductor wire and ground wires. What these lengths are depend on your tuner and also the wire's surroundings and also the ground system. /Type /XObject I only used two screws instead of four. Quantity: Sold individually.

A Balun is used to match a balanced line to an unbalanced line. but instead of the Jaycar core, we used an Amidon FT-240-43; anyhow, we also followed the UnUn with a 1:1 guanella choke and boxed everything, at that point, we . multiples, and of course different band combinations yield different /Type /Pages Both were on 20 meters at 97 watts, Icom 7300. stream Theme: Newsup by Themeansar. 49:1 End Fed Half Wave Antenna 40-10M 100W Version Bands of operation 40,20,15 & 10m using 67 feet of our UV, Ozone resistant Antenna wire. You will also need a half-wavelength length of wire (14 or 12 gauge typically) in order to construct an antenna radiator for whichever ham band you choose. 49:1 UNUN IMPEDANCE XFORMER FOR END FED HALF WAVE ANTENNA. Start winding the Matching Auto Transformer, each pass through the center of the core equals one turn. shown in the column e. var sc_project=8077274; http://udel.edu/~mm/ham/randomWire/. For example, An end fed antenna consists of a wire fed on its end, the length of that wire is not resonant with any frequency or frequencies you will be using it on. Click to enlarge. 9:1 UnUn End Fed Long Wire Lengths - Pretty Simple. ), Note that Jack, VE3EED,went SK several years agohe will be missed. 75/80 METER RESONATOR KIT FOR THE UJM-EFHW-40-10 200W 40-10m ANTENNA a more capable tuner - see AA5TB's Suggested wire lengths for 1-61 MHz operation (measured from Bullet wire point): Bands Covered (meters) Wire Length (feet) Minimum Coax Length (feet) 40-30-20-15. Antenna") is an 84' long end fed and a 17' long counterpoise (6.5' for 20m). these are the worst lengths and you want to be as far from colored <> I did not want to put the transformer in the housing until I tested it. /Producer (XnView, http://www.xnview.com) is that for a given ham band there are min and max frequencies which An excellent way to attach a long wire antenna to the Ham It Up, this 1:9 balun has an SMA output port and high-quality spring-type terminal block input for your coax. Drill out holes in the designated bottom of the electrical junction box for the SO239 chassis mount. The fewer bands, the fewer high impedance regions to avoid. 0 Some of these numbers are too close to squeeze in between them. The random wire antenna is probably one of the least expensive, easiest and cheapest HF antennas to use if you have a tuner and you want to get the "most" out of a length of "random" wire without having to pull out that calculator, doing the math, getting the center insulator built orbought, running the feedline, and all the rest that goes with putting up a more elaborate antenna. As an example, a 28-31 foot wire will typically allow 40 thru 10 meter coverage and a 43-50 foot wire will provide access to 80 thru 10 meters. For instance, to work 40m be sure the antenna is at least 10m or 33' long. << Part List: << /MediaBox [0 0 748 752] The "9:1 UNUN" are for random length wire antennas fed at the end. The 49:1, shown in my previous message, is meant for the EFHW that are fed close to or on the half wave (highest impedance) point. endobj wire lengths less than 1/4 wavelength of the lowest desired frequency Built with the same craftsmanship as all our other units, this new model will allow you to either replace your current matching unit or construct a new higher powerend fed half wave antenna. Note: My (A to B) length was 6 inches. We have also installed an additionalstud which can be used for a separate counterpoise wire rather than forcing the use of the feedline's coax shield. InJack's own words. Super Bullet Features: - Uses proprietary broadband impedance transformer design for maximum bandwidth with SWR < 2 from 1.8-61 MHz for 1500 Watt model and 1.8-30 MHz for 3000 watt model Winding 1:64 Matching Auto Transformer on the FT240-43 core. In fact, the 9:1 unun that I built is actually an autotransformer. You have to stay away from a half wavelength on any frequency. >> The following is a list of materials required to make a 49:1 unun impedance transformer for an end-fed half wave antenna. << There are numerous configurations available online that will accomplish this on multiple bands (Google search "end fed half wave antennas"). The 9:1 may work best with that length wire and a tuner, but some say that length is undesirable for the hf HAM bands. Hi guys,not really hfu related,but I tought I might ask here as I have my account. so that it is not a halfwave multiple of any frequency you want to use. [ /PDF /Text /ImageI ] 22.00 + 5.00 Postage. Recommended wire lengths for Unun models 9130, 9132 & 9135 Table shows typical SWR relative to installed wire length. google_ad_height = 600; You will note that when comparing my results with VE3EED that some of the results are a bit different. /Width 748 var sc_security="1df091cc". A png image named g.png will be created. A small ring terminal for 14ga wire that fits these screws would be helpful too. If you want a single band portable antenna you can mount pretty much however, look up this design. Its really an impedance transformer (9:1) to feed a high impedance, end fed (unbalanced) random wire which is likely to be a few hundred ohms, and transform it into something closer to a 50 (unbalanced) coaxial input, hence UnUn. Yes, with the recent surge in popularity of the end-fed half-wave antenna, the 49:1 balun has also become the defacto ratio for use with them. Dimensional Drawing of Standard Enclosure, 1:1 Common Mode Choke / Noise Suppression, Core Material Selecton for Baluns and Ununs, Antenna Matching Problems When Using Ladder Line or Open Wire Feedlines, Model 4932 - 4 & 9:1 Unun 1.5 - 54MHz - 2kW, Model 49130 - 49:1 - 80-10m EFHW - 200 watts, Model 64131e - 64:1 & 49:1 - 80-10m EFHW - Up to 1kW, Model 4116 - 4:1 Hybrid Balun 1.5 - 54MHz 3kW, Model 9130sw - QRP 9:1 Unun 1.5 - 54 MHz - 300 watts, Model 1115d - Max Choking 1:1 Balun, 1.5-54 MHz, 5kW. The counterpoise wire, This transformer is designed to be used with an end fed, Approx. 4 0 obj 20/40/17m. Multiples are on C and Figure 3 Wiring of the 9:1 voltage unun. So for 80 meters (say 3.525 MHz) this gives you about 133' of wire. The matching unit The impedance at the end of a half wave antenna is somewhere between 2000-5000 Ohms. SWR will vary based on topography, wire orientation and use of ground or counterpoise. often can't match it. So for example 80m could range in length from 120 to 133 feet. Anyway, an old friend mentioned 'MyAntenna.com' but they were closed for the summer. endobj Following the directions exactly as specified (0.47wl / 0.05wl matching counterpoise) and drilling two weep holes in the appropriate position, I had a 10 meter EFHW antenna up in less than ten minutes. A 9:1 matches 50 ohms to 450 ohms and that turns out to be an ok compromise for feeding 50-100ft of wire for general purpose SW receive. For instance, to work 40m be sure the antenna is at least The kit includes the parts needed to construct a 49:1 impedance matching network, which will transform the impedance to 50 Ohms, which will suit most transceivers. Windings are inserted into Teflon tubes increasingtotal breakdown to 10,000 volts. It is optimized for 3.5/7/10/14 MHz but will work reasonably well on all amateur bands from 80 meters thru 10 meters with a 135 foot length of wire and a short connection to ground. 9:1 or 49:1 unun for end-fed long/random wire? If the choices are. 49:1 or other high ratio transformers are for resonant "cut to frequency" antennas like the traditional zepp/fuchs antenna. The beauty of the halfwave antenna is it's a complete antenna in the sense it needs no counterpoise. Thanks for your answer,I will probably go with the 9:1 then. (Center fed is so appealing because you avoid this.). 35. About Hamuniverse I purchased a MFJ-16010 Random Wire Tuner and an LDG RU 1:1 unun.
