Antennas : 160M
  • Single support gain antennas for 80-160 meters - On 80 and 160 meters an antenna with modest gain and good front-to-back (F/B) ratio, along with a steerable pattern, can be very effective for contesting.

Antennas : 2M
  • ZR6KMD 2M Beam Antenna - This design was adapted from an article in the ARRL Handbook and built with simplicity and duplicity in mind. This antenna is a vast improvement over a standard dipole with a forward gain of around 8db with a front to back ratio of 10db.
