G'day, Got a ?? for a UHF expert.

Just fitted a Uniden UH012 to my wifes fourbie, and coupled it to unidens own independent ground antenna. Bull bar mounted

All seemed ok, but before use I thought I'd put an SWR meter on it, as I've got a bit of experience in this area but not an expert, this is where the querie showed up,

its showing full scale reflected power, which under normal circumstances is not good and means a short.

I checked it all out with my DVM and its not a short circuit anywhere from back of radio or antenna.

My question is.... do these new independent ground antennas show up as such on an SWR meter??

If so, why do they come with an Allen key to adjust, and how would you obtain best SWR under such conditions?

I have a matcher aswell if needed but dont think it should be required.

Any help from people IN THE KNOW would be appreciated,

Thanks
