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.  


FREQUENTLY 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.
