Hi John,

Any pictures of this monster?

Using a 9" line, they must be putting a few hundred kW into that stick.

Attached photo, as seen in blurb in October "High Frequency Electronics" magazine.

With 9 3/16 inch coax, this could be one of the sites with the Continental transmitter using 8974 tetrodes. One can product a megawatt I believe.

I am running 9 3/16 at work up to 3 MW peak power and about 450 kW average.

A megawatt would take care of any fading.

Funny about these April Fool's type antennas. Never any picture but a lot of verbage about the company.

I read the whole thing and don't understand why this ant would be any better than WLW's afer they lopped the top off. Maybe it's me.

I have a Thomson engineer on site but I'm afraid to ask.

I have a 0.5 WL dipole. Is it anti-fade?

Does Qatar have a Wolfman Jack to go along with this setup?
