Thanks Steve, that is kinda what I figured. I thought I tried them at VHF and
didn't have any luck getting them to work.
I found this one on digikey, it's a bit expensive though:

For that price I might as well get another tohtsu CX-140 or something like
that.

I've used similar types at VHF with bits of capacitance to tune
out the inductance of the internals but found them too touchy at
UHF. There's also the issue of skin effect and how plating behaves
at higher frequencies.
For just a few $ you can get relays like Omron G6Y/G6Z which are
rated for 1 or 2GHz. I can't recall part numbers but I'm sure some
of them (maybe Siemens/NAIS/Aromat brand) are rated for 10 or
20W at UHF.
