Recently picked up a couple of these antenna feeds and so they look ok. VSWR is a little higher than I'd like but to be expected considering they're wide band LPDA in a small package. I've got one installed on a grid dish - vertical - it really looks the part but I think a +/-45° angle would be better.
However, the RSRP compared to my iskra is slightly less (angle?) and the upload speed is also. The SINR though is awesome, from 7 to 17, now that's brilliant and has a clear effect on downlink. I get about 97/98 RSRP on band 3, 5 miles from mast so I'm already really pushing the limits of what's possible.
There's one thing that's bothering me though, the cable.
I took down the other feed because after a couple of weeks, VSWR went sky high and became useless. I now think it was actually the cable or the connectors more to the point, I'll check the old feed when I get round to it. I also don't think I did a good job wrapping the connector.
It's LMR200 cable and I suspect it's too long for the frequency, approx 8/9 meters.
I think I might need better cable, but don't want to break the bank.
1. Is it worth swapping out the coax?
2. If so, what's the best bang for buck cable?
3. Is there much difference between +/-90° and +/-45° polarisations for antenna?
