How many ground points are there in a Pcs sites? is it done in like a series or is it one ground per ground.( they are not paired up)

said by Splitpair :

It is what we use at 99% of the cell and PCS sites down here in the lightning capitol of the US and trust me those sites take direct hits on a regular basis and brush them off without as much as a blip.

Airplane, Harger makes those types of devices although they are bronze and individual.

What size grounding should I be running to the masts from the building ground. The largest ground wire I have seen is 6 guage and that is what I am running to everything.

said by AMD Phreak :

Actually Tom those are supposed to have bricks in them. They are called non-penetrating roof mounts. You load them down with the bricks which function like a ballast. It keeps the mount from falling over in even the strongest winds. :)

I just looked over the photos again and to the OP:

You need to load those down with a full compliment of bricks. The AP's look like they hold eight, and the dish holds a lot more. :)

The "Ground wire holder" is actually a buss bar from a panel box. You can can get them at Lowes, Home Depot etc...

The stuff running across the walls in that picture are supposed to prevent birds off the building and sh&*ing down the side of the building.

Hi cbc:

Where did you get the ground wire holder in the picture?

said by cbcalhoun :

Wonder why this roof does not have any lightning protection?

said by cbcalhoun :

But there is plenty of PVC tape around the weather tape on the connectors.

said by cbcalhoun :

I will try to move those antennas down a bit on those masts.

said by cbcalhoun :

Also the mast should poke higher so they are hit before the sectors. Is that correct?

said by LLigetfa :

Obviously a difference of opinion, but I cannot share yours. Public is right. The skinny stranded wires can only bleed static buildup, not lightning. Also, the masts should poke at least a foot higher than the sectors, not lower.

said by SipSizzurp :

If that is rubber tape weather proofing on the antenna connectors then you need to put a couple of layers of black tape over it or it will dry and crack in 6 months.

Edit - Next time you buy a UPS get an APC, not a smelly Belkin.

Great job on the install. It's nice to see clean installs here.

Grounding nazis.... phffff :p

I really like what I see, but here are some thoughts since you are open to them.

There are a few too many bends (in my personal opinion mind you) as you come off the arrestors/ODU's and down the mast though. Remember that lightning wants to take the path of least resistance and go in as straight of a line as possible.

I'd have the runs off the arrestor/ODU not sweep up and then down. Instead they should just sweep gently down. There are some details like bend radius and all that bullcrap but I'm not going to get into that here.

I'm off my soapbox now. I commend you on your grounding though. No one around our area spare myself, even puts that much effort into grounding rooftop or even tower gear. I've done similar jobs as cleanup of other contractors (50 rooftop sites with a total of 4 radios sometimes per site!) and appreciate the time and effort it takes do do this.

You get my seal of approval. :)

i am surprised that you did not use mats underneath the non-pen, and only have a block of wood there

said by battleop :

I guess you have pictures to show how great your grounding is? It seems like no one can post any pictures here with out the grounding nazis showing up.
