No Compromise
Communications
trap the QMS on your favorite family or business vehicle. You’ll
find it gives any HF-SSB superior frequency agility and
exceptional performance.
The SGC Smartuner automatic antenna coupler, the SG-303
extended full-range antenna, and the special exterior QMS mounting
package comprise the QMS. Mounting coupler and antenna outside
the vehicle reduces engine noise and interference.
It can be quickly installed and easily moved from vehicle to
vehicle). No drilling or vehicle modifications are required. Industrial
suction cups secure the QMS to the vehicle, without damaging the
finish, and high strength straps and buckles complete the job and give
structural integrity.
he SG-303 is a durable and lightweight antenna designed for
mobile applications. It’s a high efficiency radiator, by virtue of its
dual element design. In construction, a single fiberglass whip, helically
wound, has a primary resonance at 10 MHz and a secondary resonance
at 22 MHz. So at lower frequencies—those under approximately 20
MHz—the SG-303 will vastly outperform a conventional 9-foot whip
antenna. The QMS puts the entire antenna system outside the vehicle
for high efficiency and low noise.
he Smartuner HF antenna coupler is the working brain inside the
QMS system. It automatically evaluates and switches 64 input and 32
output capacitance combinations, plus 256 inductance combinations in
a π network. The result is over a half-
million different ways to ensure a perfect
match between the transceiver and the
antenna. Smartuner remembers the cho-
sen frequency and tuning values and will
automatically reselect these values—in
less than 10 ms—each time you transmit
on that frequency. It operates with any
HF transceiver.
