  TV Antenna Band Pass Filter (UHF/VHF Band)



Antenna Band Pass Filter is device that can eliminate all spurious and other unwanted harmonics before they have been transmitted coming through antenna system and transmission Line.

Antenna Band Pass Filter must be installed at high power level of TV Transmitter, especially for final power that used Mosfet or Solid State, because of their nature characteristics.
