Yes i have run coax into mast pipe, As long as it shield coax , should not be a problem , Doint run open wire or ladder line.in the pipe.
Had good swr on lmr400 going into a 12foot pipe and the swr is 1:1;1 on a 2 meter antenna .
Hope this helps if not ask more and we will try better!

this is only a guess, but i would think that if the mast is grounded, then it might actually help sheild the coax a bit.

You never said if it was for Ham or CB but I have found that a lot of Ham groundplane antenna's you have to run the coax thru the mast as the PL239 connecter on the bottom end of the antenna sits inside of the mast.
If it 's a CB Antenna I don't see anything wrong running the coax thru the mast.
But the best way to install any antenna or coax is going by manufactures instructions...
Most of all Watch for over head power lines...

Yes, it will help shield the coax. No, it won't hurt anything. Go for it! |
