70cm 430-450MHz BandPass Filter 2500W Extreme Power

Extreme Power 70cm 430-450MHz BandPass Filter 2500W. This filter could withstand any “Big Gun” power up to 2500W. And any commercial 70cm linear amplifier. Super low insertion loss is just 0.06dB. Put this filter after any linear amplifier up to 2.5kW and the filter will suppress all lower frequencies from 23 to 100dB and all harmonics by 26 to 60 dB. With its super low insertion loss, the filter can be used as a receiving filter before any low noise preamplifier with ATF, PGA, SAV, or SKY chips.
