Eric, Your question cannot be answered properly unless you provide the power output of your transmitter and the 12 dB SINAD sensitivity of your receiver. Therefore, I will offer some calculations based on some assumed values:
25 watt transmitter, 0.35 uV receiver, 1.7 MHz split: 237 feet vertical separation, 13,368 feet horizontal. 50 watt transmitter, 0.35 uV receiver, 1.7 MHz split: 282 feet vertical separation, 18,905 feet horizontal. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Eric Harrison Sent: Wednesday, September 03, 2008 7:18 PM To: [email protected] Subject: [Repeater-Builder] 6 meter Repeater Well regardless if whether 1.7MHz split in the 6 meter band is or is not a national US band plan split, it is an accepted split by the Kansas State Repeater Cordinator as my repeater is cordinated on 52.850/51.150 by them and has been for over 2 years. Just getting it back on the air at a new site. Wasn't trying a war here just trying to get some answers on the dB isolation needed and acceptable vertical antenna separation needed for a 1.7MHz split on 6 meters, which is my reason for posting but have failed to see anyone give the answers I needed.
