Antennas-Amplifiers 6290 2m 100W Transmit Band Pass Filters
Antennas-Amplifiers 6290 2m 100W Transmit Band Pass Filters are equally effective for both transmitting and receiving, boasting a super low insertion loss of just 0.15 dB. These Band Pass Filter are designed for use with transceivers and transverters up to 100W output. They are also ideal for placement before any wide band low noise amplifier (LNA) to protect against out-of-band signals. With their super low insertion loss, these 2m Transmit Band Pass Filters are excellent for use before any LNA or to protect receivers from HF transmitters. They effectively suppress signals from HF (1.8 – 28 MHz), 6 meters (50-54 MHz), and 70 cm (430 – 440 MHz) bands. Additionally, these filter helps reduce television interference (TVI) problems, making them particularly useful if you or your neighbors have strong HF, 6 meter, or 70 cm transmitters.
