I have a repeater, Motorola 50 watt, cellwave 6 cavity band pass notch duplexer - 38 watt output after duplexer. My brother now has a repeater 50 watt Motorola with vertex standard 6 cavity notch duplexer. Our frequencies will be about 14mhz apart. mine - 462's and his - 448's I use dx 400 max coax with a slim jim He will use lmr 400 not sure about antenna??? Looking for some opinions about antenna spacing??? I have a vertical 20' pole mount on the 20' roof Should we flip a coin and see who will be low man on a vertical split totem pole???? and how far apart? or can we go horizontal with another mount??? I've heard of two repeaters sharing an antenna... but commercial repeaters set ups by bridgecom... Any recommendations??? thank you 301
