Ted became a Ham
(W5QJR) in 1948 and was assigned a JA call
as part of the Occupational Forces of Japan
in 1950. Unfortunately, he was sent to Korea
before the license was issued. He is also
licensed as TA2TGM as a result of
engineering activities in Turkey. Ted has
traveled extensively as an Electronics
Engineer for Collins Radio, Omega T Systems,
Scientific Communications, and the Harris
Corporation in association with satellite
communications and electronic intelligence
systems. Now he travels for his own company
developing applications of the EH Antenna. |

After retirement in 1996, Ted formed EH
Antenna Systems to develop the EH Antenna
concept. One patent has been granted and two
more are in process. His interest in
antennas goes back to crystal radio set
days. His continued interest in antennas is
evidenced by inventing the Antenna Noise
Bridge in 1967 to allow detailed
measurements of antennas on a Ham budget.
The Antenna Ohm Meter is another design
example. He also wrote the book on small
loop antennas in 1984.
Ted has numerous patents, but most belong to
the companies he worked for except the big
one that got away because it was ahead of
its time. The Collins Radio Company could
not see a use for an “Infinitely Variable
Pulse Width Generator” that was developed
for telemetry to a radio controlled airplane
(another hobby), so Ted entered the design
in Electronic Design Magazine in 1964 and
won the idea of the year award in
international competition. Others saw use
for the circuit – currently used in all
power supplies and many other circuits where
there is need to convert analog to digital
signals.
Continuously active as a Ham, Ted bought a
farm in Georgia where he planned to grow
large Ham antennas after he retired. Fate
showed its humor where Ted’s EH antennas
offer performance that exceeds all other
antennas in every performance parameter, and
just happen to be smaller than any other
antenna. The farm now grows EH Antennas and
Pecans.
