Thanks Tim. Finished a homemade 1:1 balun with 140-43 core and 1mm copperwire and build a 1/4 vertikal today for 20 meters, got it tuned with the help of a VNA. Hopefully I can do some live testing later this week. Used 20 3.5 meters radials made of old network cabel and the ariel is 0.75mm electrik cabel. Mounted on a 5 meter fiberglas fhishing rod and its sitting on my garden fence ground mounted. Nice to see this video on your build. Hope to hear you on 20 meters. 73 and many thanks

Useful video Tim 👍🏻 Two tips for the viewers: #1 When using the balun for a vertical as in your example, check which side is connected to coax centre and which to the braid, as it’s the centre which makes the vertical element. #2 Often your local radio club has kit for loaning out, so that’s a good way to get your hands on an analyser if they’re a bit too expensive to buy.

Thanks Ian. I have to say I’ve not had an issue with using either connector of the Balun for either of the vertical elements. A very useful tip about clubs and analysers. 73

WB4BKO-Ned Interesting video. Very informative. All the necessary details for building a simple, inexpensive and effective antenna. You proved what a friend of mine, now a silent key and a ham for over 60 years, often stated: "if you paid more than $10.00 for antenna parts, you spent too much". Your relaxed and friendly style of presentation is a plus. I have never used a 1:1 balun on a vertical. Usually five to 8 turns of coax wound around a 2" piece of PVC pipe (when using RG58 or RG8X) near the feed point should be adequate to choke off any RF on the feed line. That piece of PVC pipe also works well as the center insulator. Thank you for your video.

@Tim G5TM: Hi Tim. Just one small point: @ 7:34 “How do we calculate how much wire we need?” The 234 imperial formula includes a 0.95% velocity factor, whilst the 75 metric formula figure you quoted does not. The correct metric formula, including the 0.95% velocity factor, should be 71.25 / f. To advise others who might read my posting, in my own antenna construction experience I have found the 0.95% velocity factor is only a nominal figure, and in real life have always found the velocity factor to be lower - even as low as 0.87% or 0.88%. A combination of various factors affects the velocity factor, such as (i) thickness of antenna wire, (ii) whether or not the wire is insulated, (iii) type of ground beneath the antenna and (iv) height of antenna above ground. In all cases, I have always found that using either formula (both with the built-in 0.95% velocity factor) has resulted in antenna legs that are longer than required, so the legs can easily be shortened to the correct length. Excellent advice from Tim, guys - if you are into serious antenna-building, get yourself an antenna analyser. Far better to spend your money there than on an ATU (which should, of course, really be called an Impedance Matching Device (IMD), which is all it does - it matches the impedance of the antenna to the 50 Ohm impedance of the radio). An ATU does NOT tune an antenna! The biggest "con" in Ham Radio! I hope this helps any newbies, and welcome to them to the hobby. Iain.
