Re: [AFMUG] CAT5e/6 tower grounding

[Paul McCall]

My 2 cents.  Never assume ANYTHING about existing ground at the tower, at the 
shelter, at the service panel.  Measure everything.  If you get a sub-Ohm 
measurement you are tied into a loop which may or MAY NOT actually be 
“effectually” grounded. Remember that CADWelds can break with a strong enough 
strike, so a ground ring around in or outside of a shelter may indeed have poor 
grounds to the actual earth.  We put in inspection boxes (sprinkler boxes) at 
every connection point to be able to come back later and test.

50% of the commercial towers we tested had at least one leg of their tower 
grounds be under spec.  For us, (and the cell guys) spec is <5ohm, but if all 
points were at 8 ohm I wouldn’t freak out.  More than 50% of the electrical 
panels we pull from had poor ground.  We either forced the tower companies to 
fix the problem or if they didn’t, magically it would get fixed in the middle 
of the night.  Pays BIG dividends in Florida.

Re: [AFMUG] CAT5e/6 tower grounding

[Jaime Solorza]

We ground all cables from antennas and/or radios at top by mast/tower and
before it enters cabinets...we use two or three points depending on length
of cable runs.   As I have stated before, we use an aerial rod with as a
direct path to ground rod/ring we can install.
We use the Franklin method which has worked well for us whether is an MDS,
Schneider or Freewave radio using Heliax RF cable or a POE powered type
radio such as Ubiquiti , Mimosa or Cambium using Ethernet cable.

Re: [AFMUG] CAT5e/6 tower grounding

[chuck]

I take part of that back, I once had a noisy telephone cable.  Rules say if 
your bonding is good the noise will go away.  In this case it was opposite.  
Turned out that the noise was not from magnetic coupling which is the reason 
you bond and ground the shields, but our cable was conduct a significant amount 
of neutral/ground current from the primary of the power line.  Their lack of 
grounding and bonding was the problem.  Once they fixed that I went back and 
grounded and bonded everything and we had a nice quiet line.

Just connecting stuff for the sake of bonding is always a good thing.  
Doing a PANI style common point ground is a good thing.  
Lightning damage is unpredictable, so no one set of rules or methods will

Lightning can be modeled as a high number of sine waves and some of your cables

elements of that energy thus not conducting it.  

Every strike has a different frequency distribution.

In my opinion the only advise worth reading comes from those that have spend

There is a reason for grounding anything ... 

Just connecting stuff for the sake of connecting to ground is not a good thing, 
actually is a bad thing. 

There is a reason why the outer core/conductor shield of LMR cable is connected 
to the ground using the kits being described, and typically that reason does 
not apply to the doing the same with Shielded Ethernet cable. 

I would strongly suggest that folks try to gain an understanding on what they 
are doing and why they are doing it, rather than hey I see him do this so I am 
going to do it as well... :) 

There are a number of great documents that address what to do and why to do 
so one such article was / is done by Chris S of Netonix ( posted in the 
netonix forums), pretty comprehensive, and done with adequate explanations.

I've never tried those ground kits in real life.  I'm assuming you 
wouldn't use them on a foil shielded cable but rather one with armor.


I don't think I would do it unless the tower owner made me do it.  Even 
where I was told it had to be R56 the guy doing the inspection was happy 
with an SS at the bottom for the Ethernet.

Try to bring all grounds back to a single point.  Bond things together 
like the ice bridge to the tower so you are not counting on the 
mechanical connection to also be the lightning circuit.


People using my products use the grounding RJ45 plugs which 
interconnect to my surge protectors.
You never know which direction the surge will be coming from either.  
Many times it comes in on the power.

I’ve heard it’s good to ground multiple places, like up by the radio, 
down by the turn to the ice bridge and inside the shelter, but how do 
you that (and is it necessary) with CAT5e/6? Do you strip a section 
off the insulation and tie the drain wire to multiple ground lugs? 
Sounds hard to do and not get water in the cable. I just have been 
running surge suppressors inside the building that the cable plugs 
into before heading to the switches/etc. What should I be doing?

Lots of opinions about this.  R56 doesn't really apply too well to things 
that are Ethernet and POE.
Try to bring all grounds back to a single point.  Bond things together like 
the ice bridge to the tower so you are not counting on the mechanical 
connection to also be the lightning circuit.

I’ve heard it’s good to ground multiple places, like up by the radio, down 
by the turn to the ice bridge and inside the shelter, but how do you that 
(and is it necessary) with CAT5e/6? Do you strip a section off the 
insulation and tie the drain wire to multiple ground lugs? Sounds hard to do 
and not get water in the cable. I just have been running surge suppressors 
inside the building that the cable plugs into before heading to the 
switches/etc. What should I be doing?
