Antennas-Amplifiers 6500 Ultra Low Loss 70cm Receive Band Pass Filters are especially engineered for high‑performance terrestrial and EME applications. Placed ahead of any wideband LNA, it prevents overload and desensitization caused by strong out‑of‑band signals while preserving the amplifier’s noise figure. It’s precisely defined 430–450MHz passband ensures clean signal reception without compromising weak‑signal performance, even in demanding RF environments.

- Designed for stations requiring maximum front‑end protection with minimal insertion loss, this filter delivers exceptionally high input return loss and rugged, reliable connectivity through N‑type female connectors.
