One of the best working repeaters I have run across was located on the outskirts of Ft Worth Texas on a 1000 ft tower. It used a single receive antenna at 1000 ft into a down converter that output on 10 meters. Several 10 meter receivers were connected to the RG-58 downlead in the radio room at the bottom of the tower. Each transmitter used a separate antenna at 500 ft and it was one of the best coverage repeaters for the flatlands that I have seen. I could reliably work it from 90 miles away with my mobile GE Prog.
Vertical split antennas can work very well indeed. 73 - Jim W5ZIT --- On Thu, 1/28/10, wb0goa <aero...@gmail.com> wrote: From: wb0goa <aero...@gmail.com> Subject: [Repeater-Builder] Duplexer vs Split Level Antennas To: Repeater-Builder@yahoogroups.com Date: Thursday, January 28, 2010, 1:49 PM Have chance to install a DB 224 at 450' and another one anywhere below it. Using LDF6 on both runs. RF solid state 110 watts out. Wanting to know the pros or cons of running both antenna close together for more height with duplexer or spacing antennas for isolation without duplexer?
