I am designing a 2 element 40 meter yagi in the spirit of the Force 12 N
element yagi's. The goal is not to be less than full size, the goal is to
avoid unwanted interactions with a near-by (13' down the mast) tri-bander.
Rather than using linear loading, I am using capacity hats to load the
The question is, how far do I need to move the '21 mhz' resonance to avoid
interactions with 15 meters? I currently have the antenna set up so that
the secondary resonance near 15 meters occurs at 22.800 mhz. The antenna is
62 ohms - j130 at 21.450. Is that good enough? I assume that it is, but
any thoughts would be helpful...
Yes - this is yet another question related to my Boonville project :-)
