coax pinched

[redneckcellphone]

i just installed a new uhf antenna to put on my trailblazer. I ran it to the passenger door where i have coax already but the coax is getting pinched. any suggestions on what to do to fix it? thanks

If you are only going to recieve on it, I'd just do the best you can.
(I know I'll get flamed for this, but I don't think you're gonna attenuate enough to make a big difference).
Maybe slip a straw or some sort of poly tubing over the pinch point.

But if you're transmitting, you're going to need to have pinch free coax.
Gonna have to try another route.
I know it takes some nerves to pop a hole in the roof, but if that's the only way you can not squeeze the coax, so be it.

Running the coax through the door makes it sound like it's a mag mount and yes, that's one of the problems with using a temporary antenna style. Solutions? Well, beyond the obvious of changing from a temporary mount to a permenant style mount you have a few options.

* You could route the coax through another path were it won't get pinched quite so easily (say around the hood and through a hole in your firewall).
* You could use smaller diameter coax and put up with the much larger loss and transmit power restrictions.
* You could look for a path through that doorway where the chance of getting pinched is less. Often near the hinges there's less pressure when the door shuts than by the latch (think folks slamming the door shut). You may also have a seam in the door seal you can fit the coax through to help protect it. There are probably more options if you look at the situation and think about it a bit.

Correct they are mag mounts and are for transmitting. Ill have to check again to see where it would be less likely to pinch

The last time I went in for a physical, the Doctor also suggested I stop pinching my coax.

If you're good with soldering, you'll have more options for penetrating the vehicle compartment and re-attaching the connector. This will both eliminate the pinching, and alleviate the swelling.

Sorry, gotta say it:

I had a pickup that an antenna was mounted on a front fender. I ran the feed line down to where the wiring from the door (in that rubber boot) connected to the chassis and fed it through there. Easy? Nope, had to take a lot of 'panels' (inside) loose to get the @#$ thing run to the radio. It didn't get pinched, but there was slack in the appropriate places so that it wasn't bent/folded/mutilated. Making the appropriate 'modifications' to that routing may work for you too. Doesn't much matter if it's a mag-mount of 'fixed', it'd be the same routing.
Good luck.
