I am so confused about how to properly ground a system. I will have a
two meter and a 440 on the roof of my house. I will run the coax down
to my sofit vents or whatever they are called and run the coax inside
the vents to my shack. Behind the wall where my rquipment will be is a
storage space that I can acess. (This is a finished attic). I will be
using a mobile radio that has two antenna outputs, one for 2 meter and
one for 440.

How do I ground the radio and does it need it? Should the coax itself
be grounded and how? Do I have to purchase one of those surge things
that screws into the coax?

The major issue is to ground the metal mast that the antennas are mounted
on. This should be done with large gage wire and the wire should run as
straight to ground as possible and be located outside the structure of the
house. The ground itself is often several copper-plated steel rods driven
into the earth (they sell the stuff you need at electrical supply concerns).
How many ground rods depends on the conductivity of your soil.
