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.)
