Antennas-Amplifiers 5960 6-meter 1500W Transmit Band Pass Filters

Antennas‑Amplifiers 5960 6‑Meter 1500W Transmit Band Pass Filters deliver exceptional performance on the 6-meter Magic Band, providing clean, reliable operation across 50–51MHz for high‑power stations. Engineered with precision‑wound high‑Q coils and capacitors boasting a Q factor exceeding 4000, this filter achieves remarkably low insertion loss through meticulous component selection and exacting tuning. Designed to operate seamlessly with high‑power linear amplifiers—including 8877, GS35, GS31, 2×GI7B, and other tubes up to 1.5kW output—the 5960 ensures pure, interference‑free transmission while offering equally strong performance as a receiving filter.

Ideal for protecting sensitive front‑end devices, the 5960 can be placed ahead of a wideband LNA (low noise amplifier) such as those using the PGA‑103+, safeguarding against damaging out‑of‑band energy in demanding multi‑multi setups, DXpeditions, or high‑RF noise environments. These filter deliver outstanding harmonic suppression, effectively eliminating spurious energy around100MHz, 150MHz, and beyond, while also shielding equipment from nearby HF transmitters. The result is a filter that not only enhances transmission purity but also fortifies receiving chains against interference. Through careful engineering and superior component quality, the 5960 provides the robust performance, stability, and signal cleanliness expected from a premium Antennas‑Amplifiers RF solution.
