80m full size 1/4 wave GPA
The 18m glassfibre pole from Spiderbeam - see The antenna itself is composed of 12m of heavy flexible insulated copper wire 4mm/2 section + 7m of same but 2,5 mm/2 on the top
A Home Brew HF Vertical From Copper Pipe
I sure have logged a lot of DX from all over the lower 48, Alaska and Canada with it! It's great for portable use or set it up for permanent station operation
A Practical 5-Band Homebrew Wire Beam
The 5-band hexbeam consists of three pieces of wire for each band. Two of the wires are deployed as a center-fed radiating element and the other acts as a director
A quarter wavelength for 40 meters
Vertical antenna 1/4 wavelength 64 radials, with remote tunner
