The only way triple f yagis work well is if the elements are swept

Well known in the VHF and UHF design world, probably almost unknown here.


That's too bad, since I've described that technique on this group a
number of times in various contexts. It allows you to make a very nice
40/15 meter antenna, for example. Bending the wires of a 40 meter dipole
in 30 degrees aligns the lobes on 15 meters, but doesn't alter the 40
meter pattern much. And of course it's widely used for TV antennas,
where the upper VHF bands are about three times the frequency of the
lower ones.

I should have known you would have stated it already. My bad.

There is also an interesting 2 meter antenna for sale on the net that
uses that method. 3 3/2 wavelength elements made as a sort of yagi as I
remember. I have no idea how well it really works.
