This being an April issue
of Popular Electronics magazine, I am not sure whether this is an April
Fools gag article of the real McCoy. The
Iron Curtain was in full
force, the Cuban Missile Crisis was a mere five years earlier
and the Gary Powers
U−2 incident just seven years hence, so anything related to the
USSR (aka Soviet Union)
was considered mysterious and possibly nefarious. Seeing Ruskie text was a real
attention-getter. The article entitled "НЕОБЫЧНАЯ ТЕЛЕВИДЕНИЕ АНТЕННА" reportedly
appeared in the April 1966 issue of the Soviet Union's "Radio" magazine (still in print). I did a
search for it and could find the March and June 1966 issues, but not April. BTW,
if you plug the Russian text into the Duck Duck Go translator, it does indeed come
back with "Unusual
TV Antenna," just as author Joseph Zelle claimed in 1966. Now, as to whether
the article's claim is legit or not, I can't say.
An Unusual TV Antenna
 Literally "An Unusual TV Antenna"
If you are an inveterate experimenter and if you read Russian - especially the
Soviet electronics hobbyist journal, Radio - the title of this article may stir
a memory. The antenna described here was originally presented in the October, 1966,
issue of Radio on page 56. The Editor of Radio stated that he had received a letter
describing a "tiny antenna" constructed by a railroad worker which was reported
to be faithfully capturing TV signals 35 and 65 miles from the worker's home.
The dimensions shown for this TV antenna would be suitable to receive American
Channel 6. From the meager information presented in the Soviet magazine, the iron
filings might act as a crude ferrite.
At first glance, the strange antenna in the drawing above appears to be a simple
dipole in shunt with a crude ferrite antenna. The dimensions given are for Soviet
Channel 4 (84−92 MHz), and according to Radio, the dipole section may be ordinary
copper or aluminum tubing. The large tube of insulated material can be 3/4" to 1
1/2" in diameter. This larger tubing is filled with iron filings and plugged at
each end with insulating washers. The length of the insulated tubing appears to
be approximately two-thirds of the length of each dipole element. No dimensions
were published in Radio for any other TV channels.
The impedance would appear to be between 50 and 70 ohms, since a coaxial cable
is connected to the antenna. Further improvements could probably be made by introducing
a balanced feed line and matching the antenna input to the feed line. Despite its
exotic structure and the obvious skepticism of the Soviets, there are reports that
this TV antenna works remarkably well. - Joseph Zelle
