Steve, Is your intended coverage area long and narrow? If so, possible strategies include using directional antennas, either both at one end of the area, where their side nulls will improve isolation, or one at each end of the area, pointed toward each other, where plain old distance will help with isolation.
A one-mile separation using commercial-grade radios seems to work for most people 73, Paul, AE4KR ----- Original Message ----- From: Steve Allred To: [email protected] Sent: Saturday, January 05, 2008 2:54 PM Subject: [Repeater-Builder] 10 meter split site I am in the process of building a 10 meter repeater and was wondering if I could get some help form you guys. What is the "best" distance separating Tx from Rx on a split site repeater without creating a big disparity between "talk in vs talk out", yet still provide the needed isolation? I have tried to interpolate the DB horizontal isolation charts but with only minor success. I also have modified DB pass cans to cover 29 MHz, so I have some pass protection on the receiver and transmitter. Output will be in the 100 watt range to an lowband DB201. Any thoughts? Thanks!
