2m High Isolation 1500W Symmetrical Relay Switch

Ultimate symmetrical antenna relay switch with the possibility to pass 1500W and direct connection even sensitive preamplifiers without the need for isolation relay.

 

 

Super low insertion loss, less than 0.1 dB, and excellent Return Loss on both sides NC (Normally Connected) and NO (Normally Open) better than -40dB. This relay could replace any CZX-3500, CX-520D, or CX-600N Coaxial Relay on a 2m band.

Measurements:
