| Re: Grounting of towers antenna and roof mounts There is a Yahoo Group on grounding that is very technical. I forget what the name of it is, but if you are interested and can't find it I could dredge it up.
Essentially you ground the antenna to the tower by simply mounting it metal to metal. Sometimes the radio itself will have a grouding point which should be bonded to the tower at the mount point. If you have cable that runs for a ways down the tower or into a box/shed then you should put an arrestor in-line and ground it to the tower at the point.
A properly grounded tower is your best place to bond anything that needs to be grounded to keep the potentials even.
Grounding a tower effectively is a science, not a hobby. It's actually more complicated that I originally thought. You need to have several grounding points per tower leg and depending on the environment/soil there are many ways to ground the tower.
Oh, and if you have a client antenna above the high point on a home you should definately run a ground wire in as straight a line as possible to bond with the electrical D-Marq of the home (or the external house ground point). This does not assure that the house/antenna will survive a direct hit, but it will stop potential differences from adversly affecting your antenna and radio at the least. |
