I would be interested in whether it is possible to design a 3-element 
HF yagi (with tapered aluminium tubing) that has a frequency 
independent feed.  I am willing to compromise top-notch performance 
for flexibility/simplicity.  My thinking is to feed with a standard 
ratio Balun (eg 50ohm or perhaps 25ohm)

Does anyone already have a model for any of the HF bands (but 20m 
would be preferred if available) that they would be willing to share?

I don't know whether I am asking for the impossible here!!

Second question..  Can I model such an antenna reliably with EZNEC+ 5 
using the NEC 3 engine?   (I have been advised that NEC3 is not good 
enough and NEC4 is really needed.)
