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. Only antenna whips with a height of
at least 25 cm are acceptable.
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).
