I wouldn't say that. Here's some pictures:

We are quoting the installation of two 5ft tall Non-Pen mounts with some small 
dish antennas as part of a security camera project. I am trying to determine 
what is required by code for grounding these masts and the cat5 lines to the 
radios where they enter the rooftop mechanical building. 


It is an older 10-story apartment tower. I did not pay very close attention to 
grounding when I was on site, I do not believe there is any sort of lightning 
rod system. There is an elevator mechanical room on the roof, where we will be 
installing a small POE switch to power the APs. Hoping someone on the list has 
done this before and can tell me what is required.

Try to find an electrical ground that is already up there for an air
conditioner or the elevator equipment.  Cold water pipe is good too as long
as it doesn't turn into PVC pipe somewhere along the way to the ground.

I used a unistrut clamp on a main beam I found inside the elevator room,
used a grinder to remove paint and installed beam clamp with a #8 ground
wire to some wbmfg gige-poe-apc suppressors.
