Broadcast High Power FM HDR Bandpass Filters. Mega Industries bandpass filters are field tunable, easily maneuverable and have various hanging options.
Each factory tuned unit may be easily re-tuned in the field for optimum performance or to allow the unit to be used for any other frequency desired.
Mega’s bandpass filers are Cross Coupling compatible with 800 kHz spacing when using the cross coupling option available for our 3 or 4 cavity filters.
The Mega-Tempâ„¢ compensated filter design allows for convection cooling without supplemental blowers. Please Contact Mega Industries if you do not see the Broadcast High Power FM HDR Bandpass Filter your high power application requires.
