Hello, on the PTP820 installation guide ( https://cdn.cambiumnetworks.com/wp-content/uploads/2018/11/PTP-820S-and-PT-820S-Assured-Installation-Guide_phn-3972_004v000-1.pdf ), Section 7-2 for a 1+0 installation direct mount, there is a caution not to remove the transparent Pressure window from the antenna interface. Is this the light-blue tinted plastic peice? IF so then I think my installation crew on a recently installed link remove it on the interface from both ends of the link.
I've been battling a slowly degrading 23GHz link for the past month (was installed 30 days ago) and many people are suggesting either moisture ingress, or the crew out in the Texas summer heat had some sweat drip into the areas that are sealed up. However, the link didn't start out bad, it just got progresively worse to the point where now the link is dropping. The relative humidity in this area is generally always between 50% an 100%, and ambient temperatures generally are typically mid 70s (Fahrenheit) for nighttime lows and mid 90s for highs. I'm wondering if there is moisutre getting inside and then when it cools off at night, the vapors condense inside, gradually, and degrade the signals.Then when it has heated up the next day, it gradually vaporizes again, improving the signal.
IT's also possible that they did not mount the radio to the dish correctly, didn't seal correctly, etc.
Thanks,
LG
