1. Topband: matching an inverted-L (score: 1): Author: sbertsch@lists.acs.ohio-state.edu (sbertsch@lists.acs.ohio-state.edu); Date: Mon, 02 Dec 2002 12:48:03 -0500 (EST); I have a 70' inverted-L that tunes up nicely on 160 meters with a series capacitor. Values found empirically are 218pf @ 1.8, 152pf @ 1.9, and 105pf @ 2.0. For testing I used some 600V micas I had on; /archives//html/Topband/2002-12/msg00022.html (7,755 bytes)

Topband: matching an inverted-L (score: 1): Author: spelunk.sueno@prodigy.net (EUGENE SMAR); Date: Mon, 02 Dec 2002 15:54:01 -0500; Steve: I use a largish air variable capacitor to feed my inverted L on 160M. Not sure of the actual cap value, but it's a lot easier to tune using this than a boxful of fixed values. Plus the air var; /archives//html/Topband/2002-12/msg00024.html (7,805 bytes)

I meant to say 170 feet. I have a 25' wooden pole at the back of the house. 10 AWG stranded, insulated wire goes 25' up the pole o; /archives//html/Topband/2002-12/msg00025.html (8,896 bytes)

Help me understand this. What is a "largish air variable capacitor" and where do I get one? How much? What is the capacitance range th; /archives//html/Topband/2002-12/msg00028.html (7,695 bytes)

By that I mean an air variable capacitor that looks like it came from a linear amp or high-power tuner.

You said 70' ..... is this total length (vertical + horizontal), or just the vertical portion? If the total length is 70' then you will indeed need some additional matching somewher; /archives//html/Topband/2002-12/msg00035.html (8,331 bytes)

Topband: matching an inverted-L (score: 1): Author: f.rura@radium.ncsc.mil (Rura, Francis J.); Date: Tue, 3 Dec 2002 15:04:26 -0500; I side with Wes N5WA on this issue - direct coax feed does the trick. Adding reactances along the way just complicates everything, and further limits the utility of the antenna. Using direct feed on; /archives//html/Topband/2002-12/msg00041.html (7,539 bytes)
