Home Brew 80/40 Meter Vertical Antenna
The total height of this antenna is 33 FT,the coils were make from 1/4 aluminum tubing
Installation 5BTV ground mounted with radials
This discussion serves to relate my experiences with quarter wave vertical antennas
Mono band antenna on 40 meters
The antenna itself is built with 4 sections of electrical conduit. 1 1/4, 1, 3/4 and 1/2 inch pipes were nested together to the right length and screwed together with stainless self drilling screws
