From what I've read about fan dipoles, one of their major shortcomings is that they are really good at radiating undesired harmonics. For example, a fan dipole for 40m, 20m, and 15m used on 40m would radiate harmonics nicely on the 2nd and 3rd harmonics of 7Mhz. That got me thinking that a good fan dipole design could be made for non-harmonically related frequencies. A few of the many possible non-resonant dipole band combinations could be: 20m, 17m, 15m 60m, 40m, 30m 15m, 12m, 10m I'm sure this has been tried before, has anybody here worked with such a design? Google found a link to a 20m, 17m, 15m fan dipole by VE2XIP, but the article is no longer online.
