I am trying to decide what to use to build 4 new 80m verticals for a 4-square upgrade here. My criteria are: 1. full size 1/4 wave verticals, no top or base loading. 2. must be able to standup to new

How about DXE (if I recall correctly) freestanding verticals and/or Titanex V80HD? 73 Mirko, S57AD David Robbins K1TTT pravi: _______________________________________________ _________________________

My first thought is 3 sections of 20G tower guyed at the top and setting on UHMW pads. Then 3 sections of 10 foot long schedule 40 aluminum pipe in decreasing diameters... You will need to shim them

Dave, I've seen the Array Solutions verticals at NT1Y. The aluminum tube elements are very heavy duty. I don't recall the diameter at the base, but they must be on the order of 4"-6". In any case, th

I'd suggest 38' or 48' of the tower with a shorter "whip." It still works with a single set of guys at 30 or 35' - the whip will be stronger (two 12' sections of tubing, double or triple walled if ne

Nope. Especially for a narrow band application. Probably just tradition and simplicity. In the pro world, matching networks on each element are pretty common (if not standard). ______________________

In an array, the effect of narrow band elements (skinny) is probably less than the fact that the spacing and phasing will be wrong with significant frequency shifts. (at least for F/B.. forward gain

Trent, Elegant simplicity is the reason insulated base verticals are the "defacto standard" for 4-square arrays. Each element is identical and most importantly there are no reactive elements between

Consider using a linear loading arrangement at the bottom of each vertical. This is what I did on my 4 square that I had in CA and it worked really well. All 4 of my antennas were made from 3" irriga

Maybe we're talking two different things here. I had 60 ft of 3" tubing up with guys at the top and middle. The top guys failed in a wind storm and the top half folded over. Same thing happened sever
