from a position of knowledge and understanding about

your products. Anything you can offer to assuage my

ignorance would be appreciated. I'd like to add

this technology to the discussion on antennas when

the book is updated.


	


     I received a pleasant phone call from Mr. Victor.

     He was unwilling to share any test data . . . backed

     by the notion that such sharing left his venture

     open to competition by folks who might exploit

     his IR&D efforts.



     This is a real risk for simple, easily fabricated

     products. He did offer the idea that the Miracle

     Whip was not an end-fed but center-fed half-wave

     dipole. He explained that the dipole is formed by

     exposing 1/4-wave of center conductor of the far end of

     the feed line. One then moves 1/4-wave toward the

     transmitter and inserts a high efficiency, common-

     mode choke. That's what the 7-turns of coax through

     the torroid core is all about.



     This inserts a discontinuity in the shield. The

     effect is that the INSIDE of the coax is a feed-line

     out to the center and the outside of the coax shield

     beyond the choke becomes one-half of the dipole.

     This means that the "wire" we see wrapped through

     the core in . . .

     is actually an unbroken length of coaxial cable. The

     magic comes from core selection for high permeability

     while offering the lowest possible losses at VHF

     frequencies. No doubt a high quality ferrite material.



     When I get the RF bench running fully and have the

     time, I'll fiddle with the concept a bit and see what

     I can confirm with the test equipment.

Folks;  

From the 'for what it's worth' dept --  

I bought a plane that had a standard Comant antenna mounted on the bottom on an almost all metal plane. Sitting on the ground, I was unable to receive weather. I replaced that antenna with a miracle whip placed in a small fiberglass portion of the plane at about the same distance from the ground. I was amazed at the results in reception and also the cleanliness of reception. Friends told me my radio coms were crystal clear. I am a happy Miracle Whip user. The antenna is also in one piece, so if you don’t glue it in place, it will serve as a great rubber duck replacement for a handheld.
