QUANTUM COUPLER
The Quantum Coupler is a device that optimally transfers the output of any of the Quantum Loop models to the internal ferrite rod in portable radios. This effectively bypasses the attenuation/filtering circuitry that usually is present in the external antenna jack of portables. Similarly, the Quantum Coupler will transfer signals to portables that have no provision for external antenna connections. The result is usually a much greater signal to the portable; some degree of control over tuning sharpness is also achieved.
DESIGN
PHILOSOPHY
There
wasn't a great deal of engineering acrobatics needed to design the Quantum
Coupler. It is nothing more than a coil mounted on a Plexiglas base. Its
cable is terminated in a PL-259 UHF plug (to mate with the Quantum Loops) and an
impedance patch allows the loops to "see" a 50 Ohm impedance.

TYPICAL USE
The Quantum Coupler is connected to the output of a Quantum Loop and then placed near and parallel to the portable radio's internal ferrite rod. It can be moved closer or farther from the radio to control the degree of coupling and, therefore, the degree of tuning sharpness and signal level.
Interestingly, with many radios, the output of the
Quantum Loop/Quantum Coupler combo is sufficiently high that it over-rides
the ability of the radio's internal ferrite rod antenna to gather signals on
its own. That is, it is usually possible to use the Quantum Loop to
determine the direction of reception by rotating the loop's head instead of
rotating the portable radio.

ASKED QUESTIONS
"Does
the Quantum Coupler work with all portable radios?"
As
far as I know, the Quantum Coupler works with all portable radios. The
only thing you have to worry about is the front-end of the portable you are
using it with. That is, the high output of the Quantum Loop/Quantum
Coupler combo can overload (or radiate to nearby radio circuitry) of radios
with less than robust front ends. The solution to this is to simply
reduce the gain of the Quantum Loop or to move the Quantum Coupler either
farther from the radio or to turn the coupler so that it is no longer
parallel to the radio's internal ferrite rod. In addition, some radios
have their internal antennas oriented in unconventional ways. Don't be
afraid to change the orientation of the coupler to obtain the best
performance.
