Pasternack Enterprises offers a wide variety of RF "devices".
http://www.psternack.com 
On page 177 of  catalog #2001A "A/B coaxial switches" are listed.
These are RF relays
They come in both 50 and 75 ohm, BNC or N connectors.
The coils are 12V@45mA max.
Switch time is 15mSec.
They are pricey, $159(US), but are well built.
We bought some over 10 years ago and used them for 8 years to switch
channel deletion
(notch) filters in the campus cable system. These are good devices.

You might be able to find a Dow antenna relay at a local ham feast.
Or, if this is for HF (below say 50MHz) then you could roll your own from a
good quality
DC relay. I have used plain old "potter and brumfields" to switch HF many
times and the impedance
bump has minimal effect on HF receive.

Good luck
