Anyone have to deal with rime ice on antenna's? We need to build a PTP
link that will be on a top of a mountain that's notorious for rime Ice.
It would be a 5GHz link with sturdy 3ft radome but I'm not aware at what
effect rime ice might have on 5GHz signal if any? Googling hasn't really
With a radome, the ice shouldn't be too much of an issue unless it gets
really thick. I had some dished here in Texas that I did not put radomes
on, thinking that the one or two days of ice we get a year would not
matter. With about 1/2 inch of ice directly on the end of the feed, my
throughput
Yeah, being in New England area we use Radome's on most of radios on
high locations, but this one would be on top of a ski mountain and there
are other cell phone provider antenna's up there covered pretty think
with rime ice. I know in general ice doesn't attenuate 5Ghz too bad, but
it looks
Use Travis Johnson's method of putting a black thick mil trash bag on
it...the blowing in the wind will shake loose any potential for rime ice.

Update after more work today.
Replaced all the electronics at one end early this morning. No real change.
Replace the cable and antenna at that end this afternoon. When we got
there the link was running with RSSI of around 67/70 and CCQ in the 50's
both ways. Aligned the antenna and I watch
To me, that really sounds like interference. Don't look at the noise
floor. Get a UBNT in spectrum analyzer mode, and let it run for a
little bit. I bet you find something bleeding over the frequency.

+1 on getting something that does spectral analysis.
Any new neighbors on the tower you're sharing? Any new gear they might have
turned up?

I will certainly be getting a UBNT something on at least one tower to
see what is going on.
I did e-mail the big tower owner about changes on it. I know we are the
only operation on the smaller tower.

Scott, I've seen this with 2.4 ubnt and the airview results were
misleading Trial and error was the only thing that helped me find the best
channel... Spent the better part of two days fighting it. I put too must
faith on the spectrum analysis and it sent me chasing my tail.

I do want to look at it, but I have tried these links in the 5.3 range
just to see what happened. No real difference, so I am not yet
convinced that interference is it, but I can not come up with anything else.

Scott,
Can you give us an idea of link distance and antennas you are using. Is
the 30' piece of LMR400 a factory made jumper of did you put the
connectors on? Weatherproofing? Lightning arrestors? Pigtail jumpers?
Trying to get an idea of what your link budget should be and where you
Interference.
Don't believe the noise floor reading.
I do not think it is implemented correctly on the Atheros chip.

You can with the newer stuff in MT and Ubnt. The noise floor in not
spectrum scan modes is complete garbage, like you say.
