Default Another Home brew 6 meter antenna

Was not much going on at home today. So I was in the shack on 20 meters.
And looking at my home brew 6 meter rig when it dawned on me.
I need a good antenna for this.

So I grabbed my calculator, tape measure and a pile of tubing.
Did this on the fly. Just wanted to see what I could come up with.
Sort of an old school antenna.
The elements are from old cb antennas. The clamps are from a discount store. The aluminum angle pieces came from exess door frames.

Boom- 1 1/2 X 16
Elements- 5' X 3/4 with tapered down tubes.

Ref= 115 1/2 in
Driven= 111 in
D1 = 106 1/2 in
D2 = 102 in
D3 = 97 1/2 in
D4 = 93 in

Spacing is 34 1/2 inches all but the last director. It is 45 inches.

Feed: Gamma Match
Tube is 14 inches.
Center conductor from RG-8 is 15 inches.

Gamma is made but not yet installed.

Will install in the morning and start testing
