Just a quick question for the group. I have two repeater sites with DB224-E antennas on them (ham/gov't split). One repeater site tends to feed back upon itself often (duplexers, radios, cabling inside all ok into dummy load, antenna SWR good). The other repeater site does this occasionally. Has anyone had any experience with this problem with these antennas ... and what is the fix (other than replacement). Station Masters do sound like a good but expensive option though.
Thanks! James
