8" is more realistic for UHF. The standard large TV antenna usually was
based on 1/2~ (40" give or take per side for the longest elements) log
periodic array. Most of the single elements worked well to make a 2m
1/4~ beam. Trim the aluminum tube down to length, drill the 3/8" holes
through the old mast, and tap them in place with a sheet metal screw.
Add a basic L balun, tune, and we're up and running. I made one of
these nearly 20 years ago that measured out around 13.5dBi on an 8ft boom.

? UHF that uses 8' elements? Uhm? Are they 2 or 3~ elements? 8' at
1/4~ is 10 meters or 28.1mhz. I'm confused?
He probably meant 8".
