The only remote antenna switches I know of that actually "work" at UHF are
the Dow-Key/Transco types, which I've used with great success for many
years. The "M" series products have 0.05dB attenuation and 100dB isolation
at 100 MHz, but are rated to operate through 12.4GHz, and are available in
SP3T through SP6T models, all Type N connectors, all completely
weatherproof, with various actuator voltage ratings from 28Vdc through
120Vac. They easily handle 1500W PEP, and are constant impedance through at
least 3GHz. Although I buy mine surplus, they are still manufactured and
readily available, pretty much "off the shelf" from Dow-Key, locally to me
in Ventura, CA. http://www.dowkey.com
