No Compromise Communications
SG-303
Specifications
HF Frequency
Ranges:
1.8 to 30MHz
Maximum Output
Power:
3 to 500 watts (PEP)
voice or CW
Dual Frequency Resonance:
at 12 and 22 MHz
Antenna structure:
Two sections, 50 inches each
Mount:
high voltage
insulated 4-way stainless
steel ratchet mount
Base:
heavy duty rubber
encapsulated spring mount
Feed-through:
high voltage wall
feed-through bushing
(hole = .890 in.)
Cable:
3 ft. high voltage
wire, one end termin-
ated by a round lug
Combine an
SG-303 with an
SGC coupler for
HF-SSB mobile
operation with
high radiation
performance
Antenna installation. The heavy duty
ratchet mount attaches to a flat surface.
Mount high voltage cable away from
the metal antenna support. Mount the
antenna at the highest point of the
vehicle. The high voltage waterproof
cable feeds through the vehicle body as
close to the base of the antenna as pos-
sible.
Coupler Installation. The coupler
mounts inside the vehicle and close to
the base of the antenna. Braided straps
make a good ground.
Antenna ratchet mount. The four-
way ratchet mount allows the antenna
to be adjusted for operation when the
vehicle is in motion.
Excellent communication under even
adverse weather conditions can be
achieved when the vehicle is moving.
Reclining the antenna. When the
vehicle is travelling, this will avoid
unnecessary exposure to objects like
bridges or trees.
SG-230 - 200 watts
SG-235 - 500 watts
SG-230PRO - 200 watts
