[Boatanchors] Re: Dow Key Relay Identification

Hi Roger, 

Most of these relays are SPDT. So, when you transmit, though the rx lead is not 
connected directly, it is floating inside the relay container.

Look on it from a radiation point of view:
What is the sensitivity of your Rx? Say it's 0.5 uV into 50 Ohm. That's -157dBW.
What's the signal you're planning to feed in? 100 W. What's the ratio? 177dB.

Can you see any possible reason in there for wanting just a smidgin of isolation?

  Roger asked:
  How important is the difference between the 
  isolated and unisolated models? I probably will never run more than 100W through 
  it.
