Interesting. What do you say to the people who claim surge suppressors
are just not necessary?

Talking CAT5 and not RF so not a huge issue. The bigger problem is
near end cross talk (NEXT) problems when the surge suppressor is very
close to a device like a switch or radio. There is SNR on GIGE but
normally return loss, FEXT, NEXT and things like that are more of a
problem.

What about insertion loss causing cables to have SNR issues?

They don't add resistance. (Actually Cambium's suppressor does add
about 7.2K ohm load on each pair but it should not hurt).
They do add a minor amount of capacitance, equivalent to perhaps a
foot of CAT 5 cable.

Someone recently told me we shouldn't use surge suppressors on towers
because they add too much resistance. What would you say about that
Chuck?
Right now we use GIGESS-HV within 3' of the radio on the tower and
GIGEAPC-HV at the tower base.
