[ARCHIVED THREAD] - Simple Mobile mount question :paint included:

Posted: 9/21/2016 9:18:26 PM EDT

Im thinking about running coax for my portable antenna setup under the bed of my truck and up the inside of the rear post. The simple question is , would it hurt anything to run the antenna through a grounded bulkhead connector ? I dont see where it would but I figured it wouldnt hurt to ask yall to verify . I dont want just have a hanging 259 end , with the bulk head connector I can cap it with a weather proof connector .

No issues here at all that I see.

Silicone grease and copious seal tape, and should be good to go.

The possibility exists for a ground loop (since you've got two ground paths, one on the coax shield and one via the
body) but there's nothing harmful about the configuration you're proposing, and if you have a loop it's not that hard to fix.

Thanks , ground loop was what I was thinking about . Wed was a long day for me so I was a bit off . If I had a ground loop the only way to fix it would to be insulate the bulkhead connector if my thinking is right on this . If thats so I would be best to insulate the bulkhead connection to begin with .

"Ground loop" is irrelevant at RF. The downside I see with that configuration is that it will be very challenging to keep that connection weatherproofed.

That. It is dang near impossible to weatherproof a PL259/SO239. They practically suck in the water (in fact there is no "practically" about it, they do). So over time you can bet on water getting into the cables and they will need to be replaced every so often. Just the same it may be the best choice for what you want to do. It is standard hardware, cheap, performs adequately and is easy to install, use and maintain.

Better off using an N bulkhead.

I have a similar setup running on my XJ's tail light housing.

Ok ordered some N chassis mounts and some N connectors .

Its mainly going to be used for portable setup not full time mobile but might as well do it right the first time .

I think you are going to have a nice setup going that route.

My tarheel is mounted with one of their mounts in the corner of my bed but it keeps me from being able to put my tool box in and I am always cautious when loading large stuff in. Maybe some day I will redo it.

Just temp setup

is the black crayon coax ?

if so, that will be fine

if it's "antenna" like your OP states, than, no, that would suck.

Seal tape and watch your bends on the coax. Especially with rg58.
