New Station Plan

Notes on proposed re-organisation of the radios and antennas.

Antennas / Tuners

Centre-fed

  • Relocated the Ranger tuner to under the balcony;
  • Couple ladder-line to the tuner using the existing balun (replace PL259 with ring terminals);
  • Replace coax feeder with single piece of RG213;
  • Provide power connection for tuner;
  • Improve earth connection for tuner (possibly not necessary given its feeding a balanced antenna);
  • Connect antenna to Antenna Socket 1 on IC-7400.

20m Dipole

  • Replace coax feeder (RG213 from radio to outside, RG400 in air up to antenna);
  • Connect antenna to Antenna Socket 2 on IC-7400.

End-fed

  • Replace Ranger tuner with ugly balun (RG400 looped through ferrite ring);
  • Connect shield side of balun to roof;
  • Replace coax feeder with single piece of RG213 (kept as short as possible);
  • Connect antenna to LDG AT-7000 automatic tuner;
  • Connect tuner to IC-718.
