These are Motorola PTP600 microwave radios which cost $16,000. per link and have been in service for less than 3 years.
One failed in Dec/13 so we installed a spare and paid to have it fixed. This spare failed in Feb/14 just as the first one came back from repair. We then had another one fail last weekend.
They claim its faulty installation and the water is coming in the antenna connectors, but that's up hill all the way!
I think its poor housing sealing with some of the water running down the internal antenna cables and into the back of the N Connectors. All of the housing screws were "finger tight". There is a hollow rubber 0.200" OD "O" ring around the housing. I measured the maximum crush at 0.011" which doesn't seam much to me anyway.
I'm trying to figure a way to seal it, but still allow me to get the case opened. I saw some one mention "Vacuum Grease" but I can't find out where to buy that.
Any ideas guys?
Thanks
