Connect a wire to the top and run it down about 2-3 feet out from and parallel to the tower and feed it with an L network against ground radials at the base.; /archives//html/Topband/2011-09/msg00144.html (8,130 bytes)

Topband: tower vertical (score: 1): Author: "StellarCAT" <rxdesign@ssvecnet.com>; Date: Tue, 31 Jan 2017 08:43:55 -0500; Hello Bob, When Ive modeled a 160 vertical interior to an 80M 4 sq I find the vertical interacts terribly with the 4 sq. The tower would need to be broken up in to 3 sections ... not a simple task...; /archives//html/Topband/2017-01/msg00107.html (7,360 bytes)

The best installation involves a genuine tapered bottom section of the type made to accommodate a ceramic base insulator. Usually when; /archives//html/Topband/2017-01/msg00108.html (8,302 bytes)
