What kind of feedline, and cables connect everything together? ----- Original Message ----- From: "Scott" <[EMAIL PROTECTED]> To: <[email protected]> Cc: "Scott" <[EMAIL PROTECTED]> Sent: Friday, December 10, 2004 10:51 AM Subject: [Repeater-Builder] Desense Problems > > > Hi All----I've got an installation here where I have three 2 meter antennas > and a 2 meter repeater that will only operate on one of them without serious > desense. The antennas are a simple J pole, a Hustler G7 ---144 and a small > triband vertical.
