You wouldn't use the ground kit with a foil shield. You'd get an
outside plant cable with armor on it.

How does it go on without nicking that thin foil? Is there a tool for
the Cat5? I looked at the Commscope installation guide and it said
smooth copper coax (Heliax) or braided.

We use those on super flex but not on heliax...use the other old

So, something like this then?

Simple: buy cat 5 grounding kits for
Shielded cable. Use them at top, middle and bottom. No more no
less. Doesn't involve cutting cable just connect into shield and
water proof like hell.

I would NOT put Cat5 surge protectors every 50-75 feet, you will
likely get Ethernet errors and/or negotiation problems. At most
there should be one at each end.
You are probably thinking of coax, and even so I suspect those
are shield grounds, not actual surge protectors.
I do agree with not making your antennas the highest thing on the
tower if you can help it.
If you must use an omni antenna located at the top, I have had
some success with a COAX surge protector between the radio and
the antenna. Polyphaser makes some DC blocking types that work
OK and aren’t too expensive. If lightning hits, the omni is
still probably toast, but it might save the radio.

*Subject:* [AFMUG] Static & Nearby Lightning Issues
Here goes...
We have a new 118' Super Titan Max tower that has been
grounded per manufacturers recommendations. Each leg is
physically bonded (not exothermically) to a 10' ground rod, all
ground rods are then connected to each other in a ring. The
equipment cabinet is bonded to an 8' ground rod and tied into the
meter base grounding as well. The two ground rings are then
bonded to each other in 2 separate places.
With that said our issue has not been with the grounding,
but with the dissipation of static at the height of the
antennas. We currently have had the worst problems with the 3
Cyclone 2.4 antennas which are currently located on masts at the
top of the tower. We have also had issues with a couple of the
5.7 Cyclones located below the top of the tower, but not as
frequently. The center-line of the 2.4 APs is 120' AGL, the
height of the tower is 118' AGL. We currently have WB-GigE-APC
surge arrestors located in the cabinet which is located 10 ft
from the base of the tower.
After doing some research through various Cambium manuals
and the Motorola R56 manual, I have some idea what our issue is,
but would like to bounce those ideas off the community. My
thought is that we neglected to put surge arrestors at 50' to 75'
intervals (as recommended by the Motorola R56 manual) and 1 at
the top for use in thunderstorm areas. Also we may need to lower
the APs to a minimum of 2ft below the top of the tower (per the
Cambium manuals for various antenna types).
Any suggestions or comments would be appreciated. What have
you done to mitigate this problem? Etc...
Thanks,
-Ed
