Antennas-Amplifiers 6560 70cm 1500W Low Pass Filters are a passive RF device engineered for clean, reliable operation within the 70 cm amateur radio band. Designed to pass all signals within its specified 430–450 MHz operating range while sharply attenuating higher‑frequency content, it effectively suppresses harmonics and out‑of‑band emissions that can compromise signal quality or cause interference. Built for demanding high‑power environments, these filters supports up to 1500W, and feature a 12VDC cooling fan, and durable N‑Type female connectors for low‑loss, secure connections.
