ok, thank you. I have a pole off the side of the house (about 20 feet away), its metal straight into the ground. Used to be used for a dish, if i mount it on there and run my coax under ground to the house will i still need to meet national electric code? The antenna should ground being attached to a pole that goes right into the ground correct? Its not as high but i sit on top of a big hill looking into town were I'm looking to transmit to.
No, it's not suitable for grounding.
The support structure needs to be properly grounded. A random amount of galvanized mast in the ground or in concrete isn't suitable. You need to have a ground rod near the base and properly connected to the mast.
That ground rod needs to be bonded to the house system. All your grounds need to be connected or you can get a difference in potential, and that's a bad thing
Cable underground isn't safe. All that energy hitting the ground will dissipate, but not before finding various paths. That would include your cable. I've had it happen at work. Back in the early 90's we had a strike hit the ground. It induced enough energy into a copper cable to blow out a terminal server system that fed multiple buildings.
Your install has to meet NEC. If it doesn't, you might get away with it. In the event of a strike, or even nearby strike, that does any damage to your home, the insurance company is going to look for ways that would result in them not having to pay out on your claim.
It's your house, your radio, your cable, your insurance policy. The decision is up to you. If you like to gamble, then have at it. If you want to do it right, NEC.
