QUANTUM  Q X  LOOP v2.0 
The Quantum QX Loop v2.0 is a 7.5" ferrite rod antenna that covers 530-1800 kHz.  It features a double-balanced JFET/JFET amp, a tilting loophead, and Q-multiplication.  The Quantum QX Loop v2.0 replaces the original QX Loop and QX Pro Loop and also accepts loopheads for the LW and Tropical SW bands.  It has an external antenna connector so that the loop's circuitry can be used as a preselector.
Price:  $199 plus S+H

QUANTUM  Q X LOOP v2.0 Plus+ 
The Quantum QX Loop v2.0 Plus+ is identical to the Quantum QX Loop v2.0 with the exception that its amplifier is of the JFET/MOSFET design and the Q-spoiling control is continuously variable (as opposed to having a 3-position switch).  The JFET/MOSFET amp provides increased gain (but with a slightly elevated noise floor) compared to the v2.0 model.  The Q-spoiling control permits finer Q adjustment for use with a phaser or to prevent overloading if the loop is used as a preselector.

QUANTUM PHASER 
The Quantum Phaser is a broad-band phasing unit that combines the signals from two antennas to create a steerable null.  It is optimized for use in the 530-2000 kHz frequency range.  When used with a Quantum Loop and an external antenna, a cardioid receiving pattern can be achieved.  Ergonomically designed, it also functions as an antenna switch.

QUANTUM STICK PLUS+
Known as the Q-Stick+, this unamplified antenna booster is designed for use with portable radios.  By placing it in close proximity to the radio, a boost in signal is obtained.  It can also be used to optimally couple the signal from an external antenna to a portable radio's front-end circuitry.  The Q-Stick+ covers both LW (150-530 kHz) and MW (530-2000 kHz).
Price:  $52 plus S+H

QUANTUM COUPLER 
The Quantum Coupler is designed to optimally transfer the signal from one of the Quantum Loops to the ferrite rod of a portable radio (thereby bypassing the filtering circuitry usually present in the external antenna circuits of portables).  The result is generally a much greater signal level.
Price:   $15 plus S+H

BATTERY PACK 
This is an external battery pack that holds 8 D-cells to provide 12VDC for powering any of the Quantum Loops or Quantum Phaser.  It comes with two removable patch cords that are fitted with 2.5mm phone plugs to power two Quantum devices at once.  Batteries not included.
Price:  $15 plus S+H

ACCESSORY PACK 
The Accessory Pack includes one 12V AC/DC adapter fitted with the 2.5mm plug required to power either the Quantum Loops or Phaser.  The Pack also includes a 3-foot UHF-UHF patch cord to connect the loops or phaser to a standard UHF jack on a receiver.
Price:  $10  
AVAILABLE ONLY WITH LOOP OR PHASER PURCHASE
