Warranties and insurance are about the same…..they only cover stuff that 
doesn’t happen.

Subject: Re: [AFMUG] Surge protector on tower

 

We do the double surge suppressor thing on our Cambium APs as well.  Still get 
AP failures, but those are almost all 450Ms that get water in them.  Of course, 
they would all fail after the 1yr warranty, but then Cambium extended it to 
3yrs on newer units; great new, right?  Weust had another get water in it 
inside the 3yr period, and now they are saying water damage voids warranty.  I 
ask them how it's our fault the unit's weather proofing failed, and after 
waiting months for a response on the ticket, I get a copy paste response of the 
exact same "water damage voids warranty" line from before... Not happy.

For most of our Cambium 450 and 820 gear we install the surge suppressors at 
the top and some type of surge suppressor at the bottom.   The upper is usually 
the Cambium spec unit.   The lower unit may be Cambium, Chuck’s surge 
suppressors, or where we are using CTM’s it's the internal surge suppression.

 

While I have the same concerns about the SS failing and requiring an extra 
climb we have had enough bad experiences with AP failures that we install the 
tower top surge suppression.

A lot of installation guides tell you to put a surge protector at the bottom 
and top end of a cable going up a tower.  Does anyone here actually do that?

 

Every installation I’ve seen in person has only had them on the bottom.   I 
think the fears people have are the SS housing leaking up or otherwise having 
to climb for a problem with the SS.
