Hi I have purchased a sirtel gamma 2r aerial and installed it in my van it has good ground plane connection as rubbed back to metal
Cable is ok and no shorts
The swr is 2.5 on ch1 and 10 on ch40
I cannot see anyway of altering the length of the aerial to adjust the swr ..
It's a brand new aerial and lead and on a bog standard 27/81 cb radio
Any ideas anyone ...

those readings indicate either water in the coax or a bad earth 3rd cause could be reflection off the roof
