The diversity switch dies in the cm9. drops rx 6-20db... Data Technology wrote: CM9's are pretty reliable, but when they have failed for me it is usually with the receive going out. The receive signal will drop about 10db.Keep in mind that with a link you have to figure out which side is giving you the trouble. It could be either tower that has the problem. If it was the CM9 then I would think you would have a signal on one side that was better than the other. If the signals are the same on both ends then there is something that is attenuating both the transmit and receive signals. The only things in common would be pigtail, lmr400 and antenna feedhorn. But it could be on either tower.

There's a strong chance there is water in the jumper and changing it might fix it. There's also a chance that the feedhorn has failed. If you end up changing the feedhorn, consider putting a radome on the dish to protect the feedhorn from weather. It's not necessary, but it is additional protection.
