G'day,
I have a copy of the ARRL "Yagi Antenna Classics" on order but also 
thinking about getting a copy of "Physical design of Yagi Antennas" by 
W6QHS.

Now if I could only get the software of the 20th edition without having to 
replace my 18th edition rather earlier than is reasonable.

Why not download a (free) copy of one of the NEC based programs (4nec2 or MultiNEC) and it will crank out the feedpoint impedances, etc. quite nicely?  They'll even do some optimization.
