The ABF128 provides additional selectivity to any receiver's front-end by reducing a multitude of unwanted strong signals from reaching and saturating the receiver's first mixer stage. Pyramid Communications designs and manufactures a complete line of high selectivity Band Pass Filters and narrow bandwidth Notch Filters for use with the SVR Series Vehicular Repeater. VHF and UHF in bandpass and band reject designs. Band Reject Filter (Band Stop Filter) features: Band Reject Filters are available as fixed and tunable, narrowband filters or wideband filters, supporting bandwidths from 1% to 200%, in configurations and topologies. The proposed filter is based on quarter-wavelength helical resonators which allow for improved results in terms of volume occupation with respect to traditional coaxial cavity resonators, while maintaining relatively high Q-factor values. CF7W 174-216/470-806 is low loss pre-selector filter that passes VHF chs 7 thru 13 and UHF chs. The ionospheric multiplication happens usually in the lower part of the VHF wave, mostly frequencies lower than 70MHz. Our dual-band vertical antenna was on the Mission Control Center roof in the antenna farm. Filters can be constructed in x to x sections with an available Q range of x GHZ to x GHz , in tunable bandpass or band reject notch designs. 01 to 40 GHz (L band, S band, C band, X band, Ku band, K band, Ka band) ERI offers a series of high rejection, low-pass harmonic filters for transmitter power levels up to 45 kW for high band VHF applications.
