What is the general consensus for where the 4 square should be resonant? If you want to cover phone and cw, is it best to; - set spacing and length of 70 ohm lines to 3.650. Then resonate verticals a

elevated feed Jim at Comtek recommends that all of the feedpoints be at the same level, but I'm not sure what happens if you don't do that. Presumably the pattern would be affected, but I don't know
If it were me, I would resonate and space the verticals for 3.510, and use switched capacitors to QSY to the SSB window. The caps are a much less lossier proposition than coils, and you have more ca
Hi Ken If there are any farmers around your area, chances are you can get some irrigation tubing for a good price. I found some damaged sections just for the cost of hauling them away. 73 Tom W7WHY -
Greetings All I have recently constructed a 4 square for 80 meters. It has performed wonderfully so I thought I would share some notes about itFirst, a disclaimer- I'm not an engineer- my data is fro

Paul, Thanks for reporting your results in detail. They will be invaluable to anyone putting up a 4-square, especially on 80M. Just a few questions/comments: 35 I had some trouble visualizing this. A

This is an excellent thread. dick.green@valley.net writes on 31/08/99: least 1/2 wavelength from any metal structure, especially a tower.< However, where it is a tower (as opposed, say, to a metal bu
My compliments to Paul on a very nicely written and informative article. Great job Paul! Two years ago I put an 80 mtr 4 square here using the K8UR configuration ("Lazy H", or "bent dipole") shown in
I am a little ways from putting up either a phased pair or a 4 Sq. on 80. I noticed that Jim, VE1JF is using the F12 verticals. I was curious if there is a consensus on which verticals are best for a
<< K4SQR, Jim, at Com Tek makes a great product and provided a lot of ideasit was nice to have a product actually work out of the box ...the hybred coupler and Jim's design have worked great! >> Ditt
curious F12, Ken and Readers; Top loading is preferred for shortened verticals, then center coil loading, and last place is base coil loading. So the Force-12 linear models and the Gladiator Top Load
