All the questions answered? Any topic is eventually tiresome, but not
everyone tires of it at the same time. Gain per unit length is likely
not a straight line at any particular frequency. There is probably much
more to be said about best coupling for maximum gain.

There was an article by Joe Reisert, W1JR in the December 1986 issue of
"Ham Radio" about a 28-element, 21-foot boom, 432 MHz (about 70 cm WL)
Yagi Joe built. The gain was about 19 dBi, or about 0.9 dB per foot at
432 MHz.

The pattern shown and gain are said to come from MININEC.

Hi Richard
Unfortunatly shortly after making his last post Art was
rushed to hospital and underwent emergency surgery to remove a
miss-behaving gall bladder.
At the time of writing I have been informed he is recovering and
hopes to be home in about a week or so.
