INSTALLATION NOTES

  1. The 50 Ω cable between antenna and diplexer should be kept as short as possible (preferably not more than 1 m).
  2. Some communication antennas have insufficient height to ensure satisfactory broadcast reception. Only antenna whips with a height of at least 25 cm are acceptable.
  3. Tuning: The antenna is tuned for best SWR at the operating frequency as usual. The filter is factory-tuned and ready for installation.
