    Quite true. Depends a lot on the internal design.

    Many of the old "Midland/Calrad/Realistic/et al." CB SWR meters from the 60s and into the 70s were designs that will work fine at VHF and they're actually more sensitive at VHF than at HF because they used stripline couplers that had more coupling at higher frequencies; as such even a few watts at VHF could drive them to full-scale for the forward reading, although it might take more than 100W on 80m to do that.

    I'd just "try it."

    I use the Vectronics PM30UV. It has calibrated ranges for 2M, 1.25M, and 70cM. They don't cost much.

    Thanks for that recommendation . As I'm just starting out and only have a Hand held VHF/UHF set at present I'm not sure which bands I might get into in future as It's about £125 and a bit out of budget at present . there are ones which can cover the lower HF range up to 550mhz for similar money are they any good ?

    Not to my knowledge. They're either optimized for HF, or VHF/UHF as far as I know.
