No, this is in the middle of nowhere there aren't any commercial systems that cover this area. I've run my SDR setup looking for anything around the frequencies in use and didn't see anything. Is...

I've put a VSWR meter on it and got about 1:1.2 from that on both lines. So nothing jumped out there. Additionally, the RSSI when no...

So looking at that video of the two repeaters on the same antenna it looks like they just added an extra band-pass/band-reject filter after the duplexers. Is there any reason I couldn't use a notch...

Any experience with the superflex stuff used about 3 times a year (pulled out of box, unrolled, put on tower, used, pulled off tower, rolled back up, put back in box all 3x)? I'd love lower feedline...
