Impedance matching is another issue. If you use a sparse r; /archives//html/Topband/1998-12/msg00091.html (7,819 bytes)

Re: Topband: Inverted L questions (score: 1): Author: Telegrapher9@aol.com; Date: Mon, 20 Nov 2006 13:46:56 EST; Peter, a slightly short Inverted-L with a shunt coil to GND might be the way to go since you don't have a variable capacitor. The 65' tall Inverted-L has a radiation resistance of 18 ohms. Depending; /archives//html/Topband/2006-11/msg00130.html (8,039 bytes)
