Antenna Grounding Question

[Cpch64]

I have done a good bit of reading but I am still a bit unsure of the grounding situation I am in.  I have installed a Ed Fong DBJ - UH antenna (3/4" Pvc Pipe) and inserted  it 10" into a 5 foot long 1 1/4" pvc pipe (Mast).  This is then mounted to my chimney with metal chimney straps.  My understating is that is that I would not need a ground in this situation.  I would appreciate any insight as to weather this is correct.

I will add the antenna is working great reaching out 35-45miles in south Louisiana.

Thanks,

I'm pretty sure your radio/antenna is already grounded.  The question you should be asking is if you should have lightning protection.    Those answers are way more entertaining.

A picture is worth a thousand words, right?

Look at page 3 in this document. They show the simplest solution for your situation:

It simply depicts a lightning arrester inserted into the feed line right where it enters the house and then connects the lightning arrester to your grounding bus. It’s a direct connection from the shield to building ground and a gas discharge tube to connect the inner conductor to ground to protect against static.
