Welcome to the forum. Three phase power was invented by Tesla, a Croat.

3 phase power works fine when the grounds are correct. The key is that neutral and ground can be connected only once in each building. If there are subpanels, the ground and neutral must be isolated in the subpanel. The antenna ground must be bonded to the power ground.

Vjeko,

I couldn't open your attachment, thus the trials of using a DialUp.
I have very little to ad to TG's informative comment.

Customarily, it is not necessary to ground twice.
If you do, just leave enough slack in the Cable, to remove the Block IF you have loop problems. Or, if this is inconvenient, use a Inline Connector (coupling) to just bypass (and remove) the second Block.

The Equipment will be grounded through the Shield of the Cable, and no further grounding of it is necessary.

Have a good Day !
S.W.

Houston - much appreciated !,
hate that when you feel you need to ask a question but you've really been
sleeping in class or like me very rusty regarding hands-on work
- I checked all F-connectors on the multiswitch with a voltmeter and shield is
connected through i.e. no further earthing needed.

One thing which I didn't get feedback on - my "problem" of the nearest grounding
connection being 1 floor above the dish/on the roof (the lightning protection
which is connected to ground on the other three corners of the house) - any problem of pulling a
grounding wire UP to the roof (next to galvanized rainwater pipe) ? I know current
likes low resistance but was not sure how smart it is to have grounding going up
to the roof when lightning is hitting down. The galvanized rainwater pipe goes
from roof to ground but there is no grounding on the corner of the house
where the dish will be (many thanks to the electrician )

What makes no sense is how if your grounding it outside, there is still the option of a surge protector for inside the house. How does the surge protector's function differ from the ground block outside of the house? Hm, just read Houston's post! Well In that case, I would just buy a surge protector and be done with it if your dish was over say 20 ft from where your electrical service box was.

But, since you did ground, that was the best for you to do. Pretty much every installer will run a copper ground from ANY point at the customer's house to the service ground.

I had an inspector fail an electrical inspection on a 4 unit apt because the directv installer didnt ground anything!!!!! Cost the owner 220 bucks!!!
