FL3BPMH Diplexer/Triplexer
The FL3BPMH is a passive bandpass filter/combiner with 1,2 and/or 3 inputs. It is designed to pass standard TV bands with an insertion loss of
< 2 dB, whilst rejecting unwanted out of band signals, including AM, 26/27 MHz CB radio, FM radio (switchable), paging, police radio, 477 MHz CB radio and mobile phones CDMA and GSM. There is also a -12 dB low band attenuator included.
The FL3BPMH may also be used backwards as a low insertion loss band separator.
The FL3BPMH is designed to fit in the MHB001 for outdoor use prior to a masthead amplifier or it can be screwed to a wall in the plastic housing via the 4 pre-drilled holes. The unit can also be removed from the plastic housing and mounted using the KB001 bracket.
