cant remeber those rich was it like a dv27 but only alot smaller

it was about 3' long but a body or guuter mount only and it had a bit about 1" long near the bottom to adjust for the swr

Yep i do. I got a 100watt amp under the drivers seat as well to boost the rx and tx.

The amp wont do anything to boost Rx, you need an aerial pre-amp for that.

some amps have a built in pre-amp too.

I took it off, just to see if it was the problem, made no difference.

I can't remember having any problems with mobile antennae before, they'd SWR up in about 5 mins, I even checked the instructions to make sure I was using the meter right, but making the antenna shorter or longer on the adjuster made no difference to the SWR, so I guess I may have a tech/mech prob with the areil/lead/mount.

I used to run a mobile ariel on a mag mount stuck to a biscuit tin on my bedroom floor ( back in '81) and that worked fine.

Try this http://www.translatorscafe.com/cafe/...cy-wavelength/ to sort out what length you need for 1/8th wavelength. Anything bigger than this is gonna be too big for mobile use really. Beware of base loading as that affects the apparent length at RF.

If it's pretuned, you shouldn't really have a problem. Check your cable, you may have reflections if you've a) Got wrong impedance cable b) made a less than ideal job of fitting connector either end c) got any really tight bends / pinches in the cable.

In which case, he's laughing!

I was thinking of the really $$$$py 'burners' you saw in the 80's.

This one has a 25db pre-amp built in;
