Hello again! What is the collective wisdom on using guy wires as an inverted Vee? Specificaly for 75 meters, maybe switchable from side to side? Since I have the opportunity to incorporate this idea,
Hi Tom - - I've been doing just this for nearly 20 years. When I originally put up my tower, I insulated the top set of guys, and feed it with window line. I had originally intended to place a relay
Better to break up your guy wires and make separate inverted vees for the low bands. This is MUCH more versitile for orientation AND it will all you to raise the ends higher. Note that the closer the
Tom, Think about what you are trying to do from an antenna propagation point of view. As stated, you wish to obtain some kind of directivity-switching by being able to switch from one set of inverted
But also don't be surprised if it interacts with the HF tribander that you presumably plan to place just above its apex. This happened to me. Assuming your interest is DX, I would seriously consider
There's little or no difference between 50 and 70 feet on 80M. Bill, N3RR as though being take-off List Sponsor: ChampionRadio.com - Trylon self-supporting towers, safety equipment, rigging gear, LOO
N4KG response below. right? mechanism. So, would you be willing to throw away 4-6 dB gain on the highbands? Given your same conclusion, you could replace all your Yagi's with simple DIPOLES. Yes, a d
We're talking about making a switching directive array out of GUY WIRES. That's a lot of work. So, what is the benefit. That's the analysis. A pair of inverted "V"s at right angles will be very simpl
Well, yes, if all you're talking about is inverted vees. I didn't bring this up before, because a 70' tower isn't tall enough for 80 meters, but a parasitic lazy vee array (see 8/94 QST) works great
For domestic coverage and close in DX, I agree that a single 80M inverted vee at 70 ft will suffice most of the time. For SERIOUS DXing, even at 70 ft, there is some benefit (the 4-6 dB F / S referen
manageable. Try a full wave delta loop for 80m - much better than a vee in my opinion. Tim, EI8IC List Sponsor: ChampionRadio.com - Trylon self-supporting towers, safety equipment, rigging gear, LOO
SNIP I believe an inverted vee will outperform a HORIZONTALLY POLARIZED DELTA LOOP (fed at the apex or in the center of the bottom wire) with the same Apex Height since the EFFECTIVE Height of the De

Yep - my experience too. I feed mine at the bottom corner with 1:1 balun and 75ohm coax, though have also used Belden 9207 which is a screened 100ohm twinaxial, 8.4mm o.d. meant for office data netwo
