21. Re: [TowerTalk] Choice of aluminum (score: 1)

Hmmm, tube tolerance may indeed be a problem for telescoping. I don't want to order all that tubing only to find out that it doesn't fit. Perhaps the solution is to order the 24' bottom sections and

All the radials for 4 SQ arrays for 160m, 80m, and 40m I can fit on 25 acres. I guess I need to start looking for bulk wire sold by the mile too :-) Rudy N2WQ ________________________________ From: D

Scott, This in fact looks like a good solution that uses both commercial 24' sections and 6' DXE sections. Thanks! Rudy N2WQ ________________________________ From: "scottw3tx@verizon.net" <scottw3tx@

24. [TowerTalk] Nested 4SQs (score: 1)
Author: Rudy Bakalov <r_bakalov@yahoo.com>
Date: Sun, 14 Oct 2012 16:16:44 -0400
Now that the elements design seem to be established, I was wondering if anyone had modeled the impact of nesting 4SQ structures around each other. I was wondering what the impact of having a 80m 4SQ

25. [TowerTalk] Particle Swarm Optimization in ham products? (score: 1)
Author: Rudy Bakalov <r_bakalov@yahoo.com>

I was wondering if there is a PSO optimization algorithm developed as an add-on to any of the ham antenna modeling programs--  EZNEC, 4NEC2, etc. I have been working on a very long 20m wire yagi that

26. [TowerTalk] Impact of high water table levels on antennas (score: 1)

Ever since I have put up two inv-Vs, one for 80m and one for 160m, with their apexes at roughly 90', I have been puzzled by their exceptional performance. Ditto for my vertical on 40m.  I have done t

Gary, You made a brilliant point! If the same effect applies to the 4SQs, they should perform incredibly well. Rudy N2WQ I believe the high water table helps me and will help you.... but the advantag

So, what is a desirable skin depth- low or high value? Rudy N2WQ Sent using a tiny keyboard. Please excuse brevity, typos, or inappropriate autocorrect. ______________________________________________
