21. TopBand: Inverted-L question (score: 1): Author: kaufmann@ll.mit.edu (John Kaufmann); Date: Mon, 30 Sep 96 14:13:55 -0400; [stuff deleted...] These comments are essentially correct if one assumes the antenna is a standard quarter-wave vertical whose radiation resistance is theoretically around 36 ohms. However, one can m; /archives//html/Topband/1996-09/msg00267.html (10,317 bytes)

Actually, my choice of the 2 quarter-wave 90-degree phased verticals in the last statement above was a bad one for this example because this array has the interesting property that the gain over; /archives//html/Topband/1996-09/msg00268.html (10,937 bytes)
23. Topband: Inverted-L question (score: 1): Author: Steve Muenich <srmuenich@gmail.com>; Date: Wed, 20 Dec 2023 19:43:44 -0600; I have an Inverted-L question that hopefully someone can answer for me. I installed the 160m wire to the 80 ft level on a 100 ft Rohn 45 tower with top mounted yagis. The horizontal (sort of) portion; /archives//html/Topband/2023-12/msg00064.html (6,918 bytes)

First of all, I am not an antenna expert nor do I know how to use antenna modeling software.These are my thoughts based on my experience and what I remember reading.

Re: Topband: Inverted-L question (score: 1): Author: Tree <tree@kkn.net>; Date: Thu, 21 Dec 2023 07:16:28 -0800; Without getting into the measurements - I think you need to detune the tower if that is going to work at all. Probably put a trap in the bottom 20 feet. Tree N6TR _________________ Searchable Archive; /archives//html/Topband/2023-12/msg00066.html (9,356 bytes)

Topband: Inverted-L Question (score: 1): Author: Tom Boucher <tomg3olb@gmail.com>; Date: Thu, 21 Dec 2023 19:47:33 +0000; Steve, For comparison my inverted-L is similar to yours with a 94 ft vertical section and 43 ft horizontal (ish). It is on a tall tree, not a tower. Like you, I use an L-network to match it and get a; /archives//html/Topband/2023-12/msg00067.html (6,890 bytes)

Re: Topband: Inverted-L question (score: 1): Author: Michael Tope <W4EF@dellroy.com>; Date: Thu, 21 Dec 2023 17:37:47 -0800; Remember, Steve, for a given frequency more capacitance equals less capacitive reactance [Xc = 1/(2*pi*f*c)]. At 1825 KHz, 5300 pf is only 16.5 ohms reactance. That means you are only offsetting a sm; /archives//html/Topband/2023-12/msg00071.html (8,576 bytes)
