Oct 20, 2019 · I,have owned 2- of these copper J-Pole antennas dual band 144/450,MHZ, they work great, My first one was on a tower ,back in,Ohio I,painted it white,with a, non- lead paint,I,bought my ,J-Pole from ,KB9VBR,he makes these ,and other antennas also which are made from copper, which is great you put it up on a mast pipe and forget it,.I,had A ,1.1 swr reading on ,2 -Meter at the time I had a,I ...

Sep 2, 2017 · I've had my MFJ 949e tuner for over 15 years and it still works well. With my faithful home-brew 40 meter folded dipole that's constructed and fed with 300 ohm twin-lead, it terminates into an MFJ balun and from there RG-8X coax. Like the MFJ tuner, the balum is a …

Dec 20, 2020 · It has been a no brainer for me the maximum distance spread I could get was 95 feet from a tree 60 feet high to a pole 20 feet high, a big sloper next to a massive redwood but still gets out and tunes fine with the LDG 600 remote tuner via a DX Engineering 1:1 balun plus I did put a 250 pf of door knob capacitors in series out of the balun to tune 80, works great, Geoff

Jul 7, 2019 · Now if you're talking about shorting the feed feed "end" of the transmission line, I.E. like using a piece of parallel transmission line as an end fed antenna, using a single wire feed to both wires of the "twin-lead" That might be different but probably not much different than a single end fed wire.

Jun 20, 2021 · Hi Julian, Full-wave loops (aka Sky loops) are my antenna of choice; Simple. Cheap. Reliable. Multi-Band - non-WARC bands without an AMU.

Aug 28, 2019 · Version of that in an RSGB antenna book 50' long with 25' counterpoise made with speaker wire and a toroid wrapped at the end, the speakerwire goes straight into a tuner, covers 40-10, a half size covers 20-6.

Jul 13, 2023 · I also recall that PowerPole connector pairs will match the spacing on 300 ohm twin lead, but check my math on that before diving in since it is possible I recall incorrectly. I bring that up to drive ideas for anyone considering an antenna project involving 300 ohm twin lead.

Oct 4, 2016 · Like you I had A lot of very good Elmers. Can your class construct A simple dipole antenna out of A box of random wire and pvc, maybe some 300 ohm tv twin lead. I would be interested in finding out. Extra Class questions asks about how to find the frequency of A coil(#14 wire wound 22 times around A 3 inch form) ?
