The final stages of assembling the tower.

 

Here are several views of the antennas.

You can see the 4 ft x 4" steel extension to hold the 6' pully. The pully has 28 needle bearings and a grease fittting.

The OCF on the pully is 135 ft long total length. The balun is a 4 to 1 balun made of powered iron cores and #14 enamel coated wire. It is a true 4 to 1 as proven by my RF analyzer. It gives a great match on 80, 40, 20, 17 10, and the top of the 6m band.

The yagi is 10 elements, no traps, one feedline. I took some pointers from Force 12 and from Bencher. It's wind compensated and gives a great match on 5 bands. On 10 meters it is 3 elements below 28,5 but 4 elements above there. No elements are attached electrically to the boom. This provides no vertical properties what-so-ever for the yagi. It has a very low take-off angle and really doesn't begin to do well until about 4500 miles, appears to be optimum at about 9000 miles. It's very quiet. All elements are 1 1/4" OD at the center and taper from there.

I designed this antenna just for this solar maximum. Yay! It's finally here. It's not let me down.
