TYPICAL RESPONSE CURVES

 

INSTALLATION NOTES

  1. The 50 Ω cable between antenna and diplexer should be kept as short as possible (preferably not over 1 m).
  2. Some communication antennas have insufficient height to ensure satisfactory broadcast reception. Antenna whips with loading coils or matching networks may affect broadcast reception.
  3. Tuning: The antenna is tuned for best SWR at the operating frequency as usual. The filter is factory-tuned and ready for installation. The car radio is tuned for optimum reception on the MW-band by means of the antenna tuning screw (if present).
