[FoxHunt] Old Homing In Article

[R. Simmons]

It appears the article is on his website :

http://www.homingin.com/newdopant.html

He claims 20-30% BW but really it is much greater. ( if you disregard loss
of RF sensitivity ) The PicoDopp MiniAntenna "design" frequency is around 1
GHz, but I have used it at 146 MHz, others have used it even lower. ( but a
fairly strong signal is required to compensate for small antenna size )
That = several octaves of span.

Hello Foxes and Hunters,

I am looking for a copy of the Homing In article from April 1995.  It
contains information on design decisions for k0ov's new Roanoake
antenna system. Joe points the user to it at
<http://homingin.com/newdopant.html> and Bob Simmons ( WB6EYV )
alludes to the content at
<http://www.silcom.com/~pelican2/PicoDopp/PICO_MORE.html>. It appears
to deal with the need for maintaining the impedance at the antenna's
for repeatable performance.

Any insight would be appreciated.

Charles
