RF Switch Question

I am looking for a RF switch/relay, that can switch a 100 Watt
transmitter signal, 5-7MHz, 50 Ohm. Ideally it would be 4-way, that is
one input feed, and 4 possible output connections.

I need to be able to activate it from a remote location, so the
switch/relay has to be electronically controllable, with 9VDC or less.

Please use Fixed font to view, ideal component:

______*
| | Outputs (Closed when active, latching)
Transmitter | 1|-------> 50 Ohm / 5-7MHz / 100W
Input, 50 Ohm | 2|-------> Same
------->|In 3|-------> Same
5-7MHz @ 100W | 4|-------> Same
| |
--------
^ ^ ^ ^
Reset to Out #1 | | | |---- Ground (Logic)
-------------------->| | |<----- Power (Battery) (1.5 - 9 VDC)
Toggle 1 - 4** |
---------------------->| (Ideal TTL levels for reset, toggle/select)
(5VDC Signal Max)

* This could be 4 SPST TTL controlled relay/switches.
**This could alternatively be 4 different "select" lines.

Notes:

1. These are NOT coax lines/wires, just single wire in and one out for
each output, the output wires are very short in length.

2. I don't need perfect isolation between the outputs, if their is a
little leaking from the selected output and the other output lines
that will not be a problem unless it is a lot.

3. I could even use 4 separate devices SPST as long as they are small
and can handle the RF power.

4. Ideally this would be a solid state switch but a mechanical switch
is fine also as long as they are small in some form of DIP package.
The single device or 4 separate ones have to be 3-4" long by maybe
3/4" wide and 1/2" deep or smaller in total.

Any ideas what the "real" name of a part like this is, or if there is
such a thing, and if so, where I might find them. I looked around at
Digi-Key and Moser, but did not have much luck because I don't know
what to look for...

Thanks in advance.
