Greetings Kyle, and welcome to the Forum.
A simple answer to your queston is, YES
Now how you do it varies, depending on how it’s set up. When one is running Guy Wires, they can be grounded as the meet the Structure. A simple wire down to the ground, and a couple feet of Iron Rod or Pipe, with appropriate clamps. If it’s more “commercial” roof, there’s usually a “cold” water Pipe in the area, where it can be used. So, clamp to Mast, run wire, clamp to something metal which is grounded. (inexpensive Stranded or Solid 16/14 ga wire)
The general idea, is not that you’re trying to make the Ground capable of taking a Lightning Strike, but, to shunt any Static Electricity off of the system, which can cause interference. But, without any more specifics about how you wish to mount it, that’s about as close as I can get.
If you’d like, tell us more about the Mast, height and what sort of hardware you will use, and there may be more information I can provide. Many do not ground Outside Antennas, assuming that the Shield of the Coax will do. Unfortunately, most of our Equipment now, only has a Two Wire Power Cord, and
I always run a separate ground my system, the extra step will provide a much more reliable signal.
If you aren't sure just what type hardwear to use, go to the
Home Page here on the Forum, and click on the links to...
Solid Signal, Winegard or ChannelMaster, then follow thier links to Pages for that equipment.
