Antennas-Amplifiers 6505 70cm Low Loss Receive Band Pass Filters
Antennas-Amplifiers 6505 70cm Low Loss Receive Band Pass Filters are engineered for optimal performance in weak signal, terrestrial, and EME applications. Designed for direct connection to a coaxial relay, the 6505 filter minimizes insertion loss in the receive path, ensuring that wideband preamplifiers experience virtually no degradation to their noise performance. By sharply rejecting strong out of band signals, the 6505 provides stable operation in environments with strong adjacent band or high power local signals. The filter is housed in a sturdy 0.8 mm brass enclosure, providing excellent mechanical stability, long term durability, and consistent electrical characteristics over time.

Antennas-Amplifiers 5910 Low Loss 6-meter Receive Band Pass Filters
Antennas Amplifiers 5910 Low Loss 6 meter Receive Band Pass Filters deliver exceptional performance on the legendary 6m "Magic Band," offering high selectivity, a high Q design, and impressively low insertion loss. Engineered to confine received signals strictly within the 50–51 MHz amateur band, these filters dramatically reduce out of band noise, lowering the noise floor and enhancing weak signal reception. When placed ahead of SDRs or wideband receivers, they effectively remove unwanted HF, 4m, FM broadcast, 2m, and 70cm signals, leaving us with a clean and focused 6m passband. Just as important, these filters will not disturb the noise performance of preamplifiers—an essential advantage for contesting, DXing, and EME—while ensuring smooth, stable operation even in the presence of strong nearby signals. With an insertion loss of just 0.1 dB, they safeguard receiving performance without compromise, a level of efficiency achieved through careful design and precise tuning. In multi operator contest stations or portable field setups, they provide essential isolation by minimizing images and harmonic interference, ensuring crisp monoband operation even in crowded RF environments. These 6 meter band pass filters are the ideal choice for operators seeking cleaner signals, improved performance, and reliable protection for sensitive front end equipment.

Antennas-Amplifiers 6530 70cm 200W Low Loss Band Pass Filters
Antennas-Amplifiers 6530 70cm 200W Low Loss Band Pass Filters are designed for stations requiring low insertion loss and reliable front end protection across the 430–450MHz range. Capable of handling up to 200 watts of transmit power, these filters are equally effective in both transmit and receive applications—introducing only 0.12dB of loss while sharply attenuating out of band signals. Installed after a 200 watt transmitter, the 6530 helps suppress unwanted emissions and reduces interference into neighboring bands. When positioned ahead of a wideband preamplifier, it prevents overload and desensitization caused by strong signals outside the passband, making it ideal for weak signal, contesting, repeater, and EME applications. The 6530 filter employs high Q coils and capacitors with unloaded Q values exceeding 1500, ensuring steep skirts and excellent selectivity. For durability, a rigid 0.8 mm brass enclosure provides mechanical stability and long service life. N type female connectors ensure secure, low loss connections.

Antennas-Amplifiers 6510 70cm 50W Narrow Band Pass Filters
Antennas-Amplifiers 6510 70cm 50W Narrow Band Pass Filters are low insertion loss, narrowband 70cm band pass filters engineered to deliver clean, interference free operation across the 430–450MHz frequency range. Designed for both transmit and receive operation, these filters support up to 50 watts of RF power while maintaining an exceptionally low insertion loss of approximately 0.15dB, ensuring strong signal integrity and protecting overall system sensitivity. When installed after a 50W transmitter, the filters effectively suppress unwanted out of band emissions, reducing interference into nearby services. Placed ahead of wideband preamplifiers, they help prevent overload and desensitization caused by strong adjacent band signals—making them well suited for weak signal work, repeaters, and RF dense operating environments. With their compact size and straightforward installation, 6510 filters integrate easily into a variety of UHF station layouts, providing a practical and reliable way to improve signal cleanliness and system performance.

Antennas-Amplifiers 6550 70cm 2500W Band Pass Filters
Antennas-Amplifiers 6550 70cm 2500W Band Pass Filters are extreme power 70cm band pass filters engineered to handle the most demanding UHF stations. Designed for operation across the 430–450MHz amateur band, these filters support RF power levels up to 2.5kW, making them suitable for high power stations and commercial grade 70cm linear amplifiers. Despite their high power capability, the 6550 series achieves an exceptionally low insertion loss of just 0.06 dB, and with the integrated 12VDC cooling fan, they maintain efficient signal transfer while keeping thermal rise to a minimum even during continuous high power operation. Installed after a powerful amplifier, the filter provides outstanding suppression of unwanted emissions—attenuating lower frequency signals by 23 to 100dB and reducing harmonics by 26 to 60dB, depending on frequency. Thanks to its ultra low loss and clean passband, the 6550 also performs exceptionally well in receive only applications. It can be used ahead of sensitive low noise preamplifiers employing ATF, PGA, SAV, or SKY devices, offering overload protection without degrading noise performance.
