Re: VHF antenna cable length
Yes it can be shortened but do not go shorter than 6 feet.
If it is RG-58 will give you a little less loss.
If it is RG-8X I dout you can tell the difference.
If you are useing a low power handheld go ahead and shorten it if your are confident
that you can reinstall the PL259 and your not ever going to move the radio to a different location.
