I've seen on various posts to refer to this for info on grounding
http://www.hdtvprimer.com/ANTENNAS/basics.html I've read it and have some concerns. Near the bottom of the hdtv primer document, under Some Additional NEC Rules, it says:
Do not attach an antenna to the power line service entrance power mast. Outside the building, the antenna coaxial and grounding wires shall not come closer than:
2 feet from exterior power lines of 250 Volts or less.
10 feet from exterior power lines of greater than 250 Volts.
1 foot from underground power lines.
6 feet from lightning rod wires.
These pictures show where I want to ground and enter my house. I have underground power. The closest photo shows orange where the power company said my line comes in and you can see my meter. The orange paint line ends at my house ground rod. The second photo shows orange flagging where I'd hoped to add a second ground rod, connected to the first, where the soil stays more moist (note it's right beneath a gutter). In both photos, you can see a pvc pipe end with orange in it - that's from a propane furnace no longer in use, so that's where I would enter the basement with coax, connecting to a distribution amp just inside. Do I have a problem with connecting the mast ground to my existing ground rod, because my power is coming in there? Is adding a ground rod in damper soil beneath the gutter a good idea? The third photo shows peak of my roof, where I suppose I'll mount a tripod with short mast, leading coax and ground wire on the roof, over the gutter, and downward.
