[Elecraft] K3S proper grounding?

[ae4pb at carolinaheli.com]

On 40m my TV turns off and on by itself when I transmit. I'm thinking that
it's related to grounding because I've not figured that out yet. I have a
roof mounted mast that holds my dipole. The coax comes down through the
roof, routes through the attic down inside the wall to the station. I've
been told I need to ground the feedline BEFORE it enters the house but I'm
not sure how to get a ground correctly up to the roof. No matter how I run
the ground a lightning strike would likely ignite my house inside the attic
if I run it inside the house. I have a low pass filter installed just
before/after the Rig. 

 

The plan I'm thinking of so far. 

1.   Run an 8 gauge dedicated power feeder from my main panel (on the
opposite side of the house) to the shack with a 20A breaker. The 8Ga is to
lower ground losses. 

2.   Install a ground rod outside my shack and run a heavy gauge to the
shack to bond with the dedicated power line ground.

3.   Ground all gear in the shack to the dedicated power ground.

4.   ?? maybe do a run of 14-2 romex with all three leads bonded together up
to the mast, install a mast antenna switch and ground it with the 14-2. 

Thoughts /comments?

 

Running only 100w into a Buckmaster 7 Band OCF dipole at 35' per the
instructions. The dipole is broadside to 45 degrees for EU coverage. 

 

Thanks in advance. I've read A LOT on grounding but haven't seen this
scenario covered. 

 

 

On another note I appear to have an allergy to my key. I just can't bring
myself to get on the air with it. I need the practice to get my speed.
