OWA yagi tapering dependency...

wrote:
I built some 15m and 10m owa's a few years ago and used slightly different
tapering. What I did was to first find the resonant frequency of each
element as designed, then match the resonant frequency of the element with
the new taper by adjusting the tip length. The overall design came out very
close to the original specs, so I didn't worry about further optimization.

I used K7NV's yagi design (Yagistress) and EZNEC, but you could probably
use a variety of tools to do the same.

Hi Tor, thanks for the help
....it seems to be proven method as I did quick check and
F/B shifted very close to the original and impedance curve was quite ok.
This was very quick as I already had both sw's.
Actual impedance measurements must wait the monster is up probably next summer...

thanks Kari B
