Out of high school I had a good friend, Jim Brewer, his handle was Double Barrel.
He bought a flat 8 element Yagi with a wire back door on a 40 foot boom.
It was a real monster, had a stub mounted above the boom with support wires to hold the ends of the boom level.
It took several of us and a crew from General Crane service to get it on the tower.
Old Green Hornet had a set of horizontal stacked 3's and the guy's down in Fresno all said the stacked 3's out talked the 8 element.
That big long boom destroyed 2 rotors before Jim gave up on it.
Last I seen that antenna his wife was using the back door to dry clothes on.......
The stack 3's stayed up for years untill old hornet passed and his family sold the house.
The best working set-up I have ever personally seen was two lighting 4 quads stacked on a 100 foot tower owned by Steve, Farm Boy west of Madera CA.
He worked as a broadcast engineer and had the connections to put them up right.
Ran a old Golden Eagle radio and a homebrew 3-500z amp.
He could hear a gnat fart on a screen door 100 miles away with that setup.
When DX started to fade for everyone else he worked stations long into the night with those quads that we could not hear....
