100_1007To all that were interest in how i made my 40 foot vertical, it was made from junk tubing that was given to me from a local scrap yard (n9bmu) known by most of us as Stuart at west side recycling. The mounts were made from diamond plate aluminum and the mount going into the ground was a 5 foot 4 x 4 ceder post sunk into the ground 3 feet with a cement base poured around it and a steel channel next to it for extra support. The matching network is a unan from dx engineering, it is a 4:1 and enables you to tune up better on 80 and 160   meters. Since the original build i have incorporated aloading coil at the bottom and with the use of a ameritron atr 15 manual tuner, I can tune up on most HF bands from 10 through  160 meters with a SWR that is less then 1:8:1. I have around 350 feet of 12 gage wire in the ground for a ground plane and taped in the 135 foot chain link fence for a little extra grounding.

 

The antenna is also made to tilt over for maintenance work when needed. Total cost to build  $ 128.00.
