Pickup bed

[cerberus]

My question is about a truck bed liner, I have my whip which was about 66' long but after doing some trimming it is shorter, and the swr's are around the 1.3 area on channel's 1 & 40 with 19 being 1.1, now to the question does plastic liner in the bed interfere with antenna? it is a full bed liner that can be removed as I have taken it out many times,and just as soon as I can I will post pictures on here of the radio and antenna.

A typical bed-liner has no affect on antennas. That assumes that antenna is mounted correctly, and not to the bed-liner, if that makes sense. From the numbers you gave, it sounds like the antenna is working.

Do you think a Rhino-liner would cause problems?

I think mine is mounted correctly, the mount is attached to a stainless steel leg from a conveyor,the leg is bolted to my bed not through the liner, that covers my bolts and then I have a old piece of coax that is serving as ground from the mount to the under side of the bed, which is grounded to the frame.And my swr's are on channels 1 & 40 it is 1.3 and on 19 it is 1.1 so pretty good in that area, I still have a little engine whine but am working on that.

Beercat,
I honestly don't see how it would affect anything about a radio, if the installation is done correctly. By that I mean that there is good metal to metal contact where needed. I don't have that particular brand of spray in bed liner, but I have had one in the last three trucks I've owned. Didn't see any electrical difference one way or the other.
