Can someone tell me if there is a PL-259 connector for UHF and a
different one for VHF? I got a 259 from Radio Shack that was labeled
for UHF. It looked the same to me so I installed it, along with a
Shakespeare VHF antenna for a VHF marine band radio. Would not
transmit, but had a steady clicking from the speaker when mike was
open. I returned the radio to the factory for repair under warrenty,
and when returned was told the radio performed at factory specs, and
to check the installation. So, now I'm stumped, and hate to try
anything else without knowing what's going on. A SWR meter check would
not help at this point. Thanks for any help.

Actually, an SWR meter would be quite helpful. Connect it between the
transmitter and the antenna cable, transmit, and see what the forward &
reflected power is. Now put it between the antenna and the cable, and
repeat. Is the transmitter putting power into the coax? Is the coax putting
power into the antenna? Is the antenna reflecting too much power back to the
coax? Is the coax returning too much power to the transmitter?

This simple meter will tell you if the problem is a bad transmitter, bad
coax, or bad antenna.
