INSTALLATION NOTES
The 50 Ω cable between antenna and diplexer should be kept as 1.
short as possible (preferably not over 1 m).
Some communication antennas have insufficient height to ensure
2.
satisfactory broadcast reception. Antenna whips with loading coils or
matching networks may affect broadcast reception.
Tuning: The antenna is tuned for best SWR at the operating
3.
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).
