# Multi band H.F. antennas

After building a 4:1 Unun vertical antenna for 20 -10 meters and liking the way it worked I decided to build a multi band inverted V antenna using a 4:1 Unun that would cover 80 through 10 meters.

The vertical antenna is made of 3 six foot sections (18 feet) of aluminum tubing I got from DX Engineering and a 4:1 Unun. The four radials are 18 feet of #14 wire. The first vertical I built I used five 18 foot wires. One for the driven element and four for the radials. I pulled the top of the antenna up in the trees about 28 feet so the radials were at a 45 deg. angle and it worked just fine.
