[TowerTalk] Questions about the HyGain HyTower theory of operation

[w2cdo at comcast.net]

Dan,

Back in the mid-70s I had a Hy-Tower up at my then-midwestern QTH without the concrete base (but guyed) and it went over in a wind event (guys failed, obviously) and it landed on my neighbor's AC service line.  Removing it was a life-threatening exercise and the next day I was bending rebar and pouring concrete.  After that, no problems.
Neighbor stayed friendly after that.

Best of luck,

Peter W2CDO

Subject: [TowerTalk] Questions about the HyGain HyTower theory of operation

Hello to the group.

I am considering making a homebrew HyGain HyTower.
My first questions is this:
The stinger at the top is not electrically connected to the top of the tower? It is insulated and there is a wire that runs from the base to the stinger. In the manual, it is called the "80 meter wire".

I am wondering why they did this instead of just electrically connecting the bottom of the stinger direct to the top of the tower.
Does anyone know the answer?

Next question: Has anyone tried to make a 60 meter stub for this antenna?
Last question: Does one really need 3 x 3 x 3 ft of concrete to hold up a tiltover 100 lb. tower and stinger such as this antenna?
