Antennas : 6M : 6 meter Yagi Antennas
  • 6el LFA Yagi for 50MHz - This six element LFA Yagi for six meters has a 1.5 inch square boom with a 1.5 inch secondary boom beneath the first. This ensures the 7.3 metre long boom will not sag and will not require any guying. This antenna has 12.3 dBi Gain and just over 23dB F/B.

Antennas : Active
  • PA0RDT MiniWhip - When experimenting with the WellGood Loop antenna, I came across the PA0RDT MiniWhip design referenced in several places. The construction of the PA0RDT MiniWhip is simpler than the WellGood Loop since there are no inductors to wind, but during my testing, I have found the loop to have slightly better performance.
