> Hello,
>
> I did a quick test with  3 pcs  russian REW14 coax relays. The setup was
> very simple:
> HP432A  power meter,  two  attenuators  (-30dB)  and transceiver.
> Measured results
> (isolation) are:
> -----------------------------------------
> 144 MHz
>  - 44,6 dB      -45,3dB        - 45,7dB
> -----------------------------------------
> 432 MHz
> -34,8dB         -35,4 dB       - 35,8dB
> ------------------------------------------
> 1296 MHz
> -24,7 dB        -25,4dB        -25,7 dB
> -------------------------------------------
> Note: this is the isolation with quite correct loaded  relay  outputs, I
> did not check the SWR,
> but the attenuators are very good quality (50 ohm) up to  10 GHz. The
> isolation has not been
> checked  with worse  SWR.
