First new site for us we are moving in.

Grounding to rack

Groudning out to tower

Ground

Inside hut

There used to be a radio station on the site who left recently. Now we have the rack and existing power etc. Looks like the Genset backs up power to the whole site but maybe only just the cell providers. The main electrical panel feeds right thru our portion of the building so I will be able to look further in the next week to determine which circuit goes where and if we also have generator back up which would be a nice bonus..

I did have a question on that copper ribbon ground from the base of the tower to the inside rack, who safe and reliable is that? Any suggestions for it or do you think it will be okay?

Should I also run an 8 guage ground from the rack to the main electrical feed panel?

Its about 120' tower we will be at 60' for the UBNT sector and PTP dish.

Thanks

copper strap is a preferred way over around wire

Cool thanks I was wondering it it was okay to ground it directly to outside where all the other grounds were or if I needed to also ground to the inside utilities?

Keep it on the site's ground. Avoid the electrical ground if you can. I would reccomend that you do a test from the grounding rod to the strap tho with your multimeter. That ground looks old.

BTW your getting an incredible deal on your bandwidth.

Also is the cell phone company on there following Motorola R56 guidelines ?

Thanks. Not sure about the cell company. Site owner had no info other then freq.

reply to viperm
Fair enough, Do they have a grounding ring ?

I just noticed that grounding rod doesn't look like a 11 foot copper coated rod. I would recommend installing a new grounding rod and moving the rack's ground over to it.

That just looks like that iron rod you weld together then build forms for and poor concrete in when your building something like a bridge.

That is one sweet site.

edit: If the cell company has a grounding ring just connect your rack to it at the rod closest to the building. It will provide more protection then that.

I see plenty wrong there...

Well I am open to whatever you think needs to be addressed as long as it does not cost an arm and a leg..

Thanks

Yes the current ground rod looks like a piece of rebar that was placed in the ground when the pad was poured. I have no idea how deep it goes. The grounds attached to it go in a couple directions and look like about 10 guage copper that go directly into the ground and possibly around. I have not investigated to much this day as I was on a time crunch. I will look further in the next couple weeks.

This is not owned or operated by a cell company they are only a tenant. I will try and dig up more from the owners of the tower maybe some old as builts or something.

reply to viperm
The rebar is a stub-up that connects to the rebar cage in the base. That is actually a pretty good ground, IF the rest of the system is done correctly (it's not).

There is a lot of scabbed-on crap there...what a mess.

Good to see you found a nice site but that site needs major work if you want it grounded correctly.

I don't have time now to point it all out but it's bad from
What I am seeing.

Well nothing is stopping me from moving forward this will be our "main" site.

So I will be investing some money to correct what issues it may have or possibly get the owners to fix one or the other. I have clients who already want service. For one I will be adding my own ground buss barr outside before entry to my eq..

Hit me offline when you do have time to discuss. For now I am going to be cleaning and mounting eq in the next couple weeks while addressing any electrical needs.

when I see what you are paying it makes me feel better

I am on two 10 floor highrises: one of them just asked me for 325 a month with a 75 dollar monthly increase every year.

After 5 years its 625 dollars a month: but, its not per antenna.

I reserve the right to do what I want in an area 6 x 6 : non penetrating roof mount

Nice!!

viperm nice pics them Ubnt sectors look small compare to them cell tower sectors LOL....

Yep it was supposed to rain all weekend but it just got really cloudy and a few drops so I figured lets do this!

reply to viperm
-92 noise in 40mhz I envy you. you can probably see upwards of 150-160 megabit's per second tcp on that link.

At only 5.8km for the link as well you are probably even within the range of airfiber.

edit: If both ends of the p2p can't see anything else 5ghz in 40mhz turn airmax off for a bit more speed.
