Duplexer Installation

A set of 6 commercial cavity filters were donated to the club which were originally tuned to ~156MHz. A right angle connector was broken but thanks to Rick KC8GQL having a perfect replacement part on hand we had what we needed to make them functional again! Previously the repeater used two separate antennas with 50′ of vertical separation to reduce desense but this was a great upgrade.
