I spent most of yesterday evening trying to set up a neighbour's CB radio equipment and more importanly, his antenna.

He's got a Ham International Jumbo, fully expanded with an EpRom chip (super-lo, lo, mid, hi, super-hi plus UK40) and the arial is a Solarcon-99 with groundplane kit. He's using exactly 21 feet of coax.

In theory that should be an ideal set-up but for the life of me I cannot get his SWR below 2.3 - I've tried adjusting the tuning rings at the base of the antenna to no avail and I've plugged the SWR meter in to the arial end of the coax to ensure the problem isn't there. He's using high quality coax, so I'm mystified as to where the problem is.

This probably doesn't make much sense to most people but I'm sure I've seen a few threads here in the past about CB radio so.....'elp!
