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 with SO239 connectors for HF use (+15 EUR)
