Antenna grounding question

Post by ExtraClass »

I am going to install a Sirio Antenna GPE 27 5/8 on the corner of my roof later this week with a adjustable outdoor antenna mounting pole. What if anything do I need regarding grounding? Also any suggestions as to antenna setup would be very helpful!

Much thanks & 73s!

That antenna is shunted so a ground rod at the base of the mast (guessing it is an all metal type pushup pole) would do for the most part. I always install an inline lightning/surge arrestor on the coax before it enters the house.

Here is a image of the bracket I will be using to put up my new antenna.

How should I ground this?

I've never used one like that for a CB antenna, not sure it would handle the wind load, that is more for small TV antenna or small satellite dish.
Anyway, grounding something like that I would first check the local electrical code for roof mounted antennas (could ask a satellite installer). I always did this for insurance reasons.
It probably will say run a bare (insulated wire can be used too) copper wire (some say aluminum is okay), 10 gauge or larger, from the base of the mount to the ground rod location, make the route as short as possible.

Yes Sir, you are correct!

In looking over this antenna mount I can now see that it will not handle the antenna that I wanted to put on it. Thanks for all the help! 8-)

I am grounding my antenna into the dirt ground and separately grounding my power supply at a different location into the dirt/ground.
