I didnt mean to give you the impression that I would be grounding the antenna to the electrical box directly. The Earth ground is at this location where all the utilities enter. There is also a large ground to piping here that clearly goes underground that is easily accesible.

Seems after some research. The antenna manufacturer was referring to a choke to keep rf out of the feed line. An Alternative with lmr 400 could be ferrite snap ons I suppose. Thanks for your input. So much to learn and consider.

Trying to decide my best option for a base antenna mount. Ive purchased a jpole to be mounted. Use location will be a room at the rear of my home. Electric panel and grounding are all the way at the front right of the home. This would be a logical place to ground any mast mounted up from the roof line but would also require a very long run of coax through the attic to the rear of house and then down. If I add a mast to roof at the rear of the home, it seems there are limited grounding options. There is a concrete walk way to traverse for any grounding rod solution, and only a water spicket coming out of the side of the house. I have no idea the routing of this pipe and where it may or may not contact the ground. This is leading me torwards a telescoping fiberglass pole at the rear of the home , perhaps attached to a concrete filled bucket with a post or some other means of attaching the fiberglass mast to that could be removed when things get stormy. An easy mount location would be at the highest peak on the roof line on a short pole where coax could easily enter the attic. Again, this would require a long coax run and a long way to reach a grounding location.

Arent you supposed to make a 4 inch loop somewhere near the top of the coax ? Mine Came with some instructions reccomending this whic are not on front of me atm. I was curious about doing this and how it would be accomplished with the thicker lmr 400 or if you need a piece of thinner coax to start with ..

Good To hear since Ive just recieved one of these. All new to me. Trying to figure out mounting solutions and coax type vs length.
