HF 50MHz 70MHz Relay Switch 1500W High Isolation

HF, 6m, and 4m ultimate symmetrical antenna relay switch 1500W with high isolation for direct connection of any preamplifier without the need for isolation relay.

 

 

Super low insertion loss, less than 0.05 dB, and excellent Return Loss on both sides NC (Normally Connected) and NO (Normally Open) better than -30dB on any frequency between 1MHz and 70.5MHz. This relay could replace any Coaxial Relay from HF to 6m and 4m bands. By ordering SO239 connectors for HF use (+15 EUR)

Measurements:

HF 50MHz 70MHz 1500W Relay Switch with High isolation. Measured Return Loss and insertion loss.

Insertion loss less than 0.05dB
Return Loss (RL) is better than -30dB

 

 

HF 50MHz 70MHz 1500W Relay Switch Measured ultimate high Isolation 6m and 4m.

Better than 75 dB on HF, 72dB on the 4m band, and 68dB on the 4m band.

 

 

Operate time including bounce 25ms.
Switching should be done exclusively “on cold” without any applied power.
