RF-relay for 500 Watts ?

Hi all, could somebody recommend me a RF-relay for up to 500 Watts.
DC up to UHF ?

Kindest regards,

These exist in forms using coaxial connectors. They are made by companies that make switches for this frequency range. I found many vendors by using "coaxial relay" and "coaxial switch" as search terms on google.

Very expensive: Agilent
Expensive: www.radiall.com (France) produce a variety of switch. The SPDT, N connetor is ruggerized enough to support 500W.
Economical: Look for N or UHF connector, SPDT, "balance" mechanism, failsafe, relais in the Amateur Radio market.

High power relay is always in mechenial format,its speed is just modest.
