Ch3 (60-66 MHz) 5-Element Folded-Dipole Yagi, Optimized with nikiml's Python Scripts, analyzed using 4nec2. If using a Metal Boom, be sure to calculate Boom Corrections (see Yagi Intro webpage).
a) AWG12 Copper Wire: On Ch3, Raw Gain = 8.8 to 10.0 dBi, F/B & F/R Minimum = 12.4 dB and SWR (300-ohms) Under 2.7. Boom Length = 136.4-in.
b) Quarter Inch Copper Tubing (QICT) or Braided-Shield in RG-59 Coax (insulation can be left on). On Ch3, Raw Gain = 9.1 to 10.0 dBi, F/B & F/R Minimum = 13.1 dB and SWR (300-ohms) Under 2.0. Boom Length = 160.2-in.
Note there is very little difference between QICT and AWG12 versions.
