We had one AF-5x link where one chain dropped by 10 or 15db (I don't remember exacty... it was awhile ago), and changing the radios and pigtails on both ends of the link made no difference. We ended up fixing it by replacing one of the dishes.
My best guess was that the feedhorn itself had some water in it (this was probably one of our oldest Rocket dishes), but by the time I got it back to the shop and dissected it, everything was dry, so I never could prove it. ________________________________ From: ubnt_users-boun...@wispa.org [ubnt_users-boun...@wispa.org] on behalf of Josh Luthman [j...@imaginenetworksllc.com] Sent: Monday, January 22, 2018 9:20 AM To: Ubiquiti Users Group Subject: Re: [Ubnt_users] AF5x bad signal problems This is what we did - new radios and jumpers on both sides. It cleared up for a few days and at this point it looks like chain1 is ~10 db lower than chain0 (which is back to the 60s). We'll see what happens after a couple of days, it's passing way more bandwidth than what we need so it isn't necessary to get that last few bits.

Both chains dropped from 60s to 80s to 95+ and the link obviously disappeared. The signals reported on the AirOS interface, I mean. Spectrum scan still shows -50 to nearby APs and -60 on the BH frequency.

Everything is covered in ice. BH is 12.5 miles north/south. Have another BH 12.5 miles north/south (in line with the af5x) with no problems. Ruled out thermal inversion or anything because of this. Any ideas besides bad jumpers/water or the dish got moved? It was only 25 mph winds, which admittedly is pretty faster for here, but just wanted to bounce ideas before climbing.
