I have a 150ft piece of Times Microwave LMR-400 in production with one
end inside structure and the other connecting to a transceiver on a
rooftop. We had some electrical storms come through in the past few
days, and one evening we lost both the transceiver and the IDU (indoor
unit) controller of said transceiver. Both were damaged and acting
strangely, replacing just one of the two didn't work. To get the system
functioning again we had to replace both the transceiver and the IDU.
My question is, assuming the damage was caused by lighting (I haven't
found any hard evidence to suggest it was, but, it seems to be the case,
awfully coincidental otherwise) -- could/does LMR-400 "get damaged" by
lightning? I feel like that's a very basic question, but I just want to
be sure we don't need to replace that cable in addition to the two
components we have replaced. Since the replacement work (two days),
everything has been fine, but I didn't know if maybe, somehow, the
internals of the LMR were potentially damaged too.
On that note, is there anyway to test an LMR cable? In Ethernet
scenarios I use a Fluke brand cable tester, is there a similar tool that
can be used for "checking" LMR-400?
