high swr

[otter8]

just put a new trucker 80 on my set up and can get decent swr on it ! put my old orbitor back on and the swr is well below 1, the swr on the trucker 80 is above 2 on channel 1 and just below the red on 40 ! tryed lenghtening the whip but just makes it worse ! anyone any ideas ? need help !

If your SWR is higher on 40 you need to shorten the whip not lengthen it

[otter8]

How much should i shorten it by ? 5 mm ?

[grom]

Try 3mm at a time & keep going until the SWR starts to go up.

[stampman]

that far out try 5mm to start with

Thanks for the help, took about an inch off the end swr around 1 on all channels now which will do for me !
