Grounding an antenna mast
 

I have an outdoor antenna that I am going to install. I need to ground it. I have 50 ft of #6 bare ground conductor. What else do I need to attach to house? Standoffs? something else? Can go up against vinyl siding? Thanks in advance

How are you going to mount your antenna...
(mast/eve/"J" Mount/ ?

No need to use the heavy wire...
Unless you are using a Mast, and required by City Code.
Get a inline grounding coupling, and use the Shield as a ground.*
A Mast may not be so tall, where should it fall, any part of it must not touch the next property.

No, don't directly attach any bare wire to your house.
If you get a direct strike, it could cause enough heat to start a fire.

There are three kinds of Lightning Strike...
Distant:
Will cause an electrical surge, which you may already be protected against through electronics in your equipment. If unknown, you may use a Power Strip which has Surge Protection built into it.
Near:
Where EMP is transmitted through the atmosphere to your Antenna. Usually messes up tuners, and there's nothing you can do to protect your equipment from it, other than what the Manufacturer has installed.
Direct:
Kiss your entire system goodbye, and, hope the molten metal doesn't start a fire.

*= Placement of the Grounding Coupling is a topic of protracted discussion.

If the antenna is outside, the coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC), the mast should also be grounded in a similar manner to drain any buildup of static charge, but the system will not survive a direct strike.

Todd Humphrey doesn't speak for the NFPA that publishes the NEC code, but he has some ideas that are helpful. The local electrical inspector (AHJ, authority having jurisdiction) has the final say if you are willing to get him involved. Some inspectors are more friendly than others; a local electrician could tell you.
