I have two high powered rigs that I want to use with one antenna. Would it be safe to use a Daiwa CO-201 coax switch for this purpose? This particular switch shorts the unselected port to ground, but the actual isolation is not specified. I just want to make sure transmitting on one rig won't nuke the other.

I just realized that I could measure the switche's isolation with my RF generator and the S-meter on my rig. I cranked the generator up on 20M (the highest freq band I use) for a reading of 60 over 9, then flipped the coax switch. The S-meter fell all the way to the end of it's range. The isolation must be at least 100db if the meter is right! I see no problem now.
