| SGC automatic antenna tuners |
On this page you will find:
The US company SGC develops and manufactures radios and accessories for
mobile use on shortwave. The products were developed mainly for commercial users,
and therefore are very solid and easy to operate. Among radio amateurs SGC ist
most known for their robust automatic antenna tuners "SmarTuner".

tuners (english, opens in a new window)
Tuning without power supply? Now possible with the new SG-211, tuning has
never been easier. Just connect a cable to the tuner, connect antenna and go.The
tuner uses four internal AA size batteries, which last usually for five years.
With it's up to date design using latching relays the tuner requires only
extremely low power, and that only while actually tuning. A LED shows the sate
after tuning. The wide impedance range from 0.3 to 6000 Ω matches any antenna.
The SG-211 offers connectors for end-fed wires or paralel wire fed dipoles, with
a few limitations also coax-fed antennas can be used as well. Wires (or rods)
from 2.5m length on can be tuned without problems and even used on 80m, from
7.5m on useable also on 160m. The tuner can be used up to 50MHz (6m). Max.
transmit power is 60W PEP or CW, on low bands max. 30W.
Tuning lasts approx. 2.5 seconds, once found settings are stored in 256
memories, later tuning on the same frequency works much faster.

Suitable batteries: Ansmann maxE rechargeable batteries! 2100mAh capacity,
very low self-discharge. Comes fully charged, ready for immediate use.
A new SGC tuner, very good performance with QRP radios like Yaesu FT-817, K2
or SG-2020. Power range 1.5... 200 watts PEP, 170 memories, manual tuning
without transmitting is poosible! Average DC current 230mA only. Frequency range
1.8-30 MHz, minimum antenna length 3m (9ft.) for 7 ... 30 MHz. This tuner has NO
waterproof housing as all other SGC tuners have, thus a very reasonable price is
possible.
SG-230
SG-235 von innen
|
Automatic antenna tuners suited for all
shortwave transceivers.
Frequency range: 1.8 to 30 MHz. The tuner
automatically matches wire antennas: minimum
length 2.5m starting from 3.5 MHz (SG-235: 7m),
8m starting from 1.6MHz (SG-235: 16m). Wire
antennas up to 100m length can be matched as
well.
The incorporated pi network enables up to
500,000 element combinations; the microprocessor
is built-in. The non-volatile memory stores the
element combinations even without power
connected. The non-volatile memory stores the
last 500 combinations and overrides older tuning
data. Recurrent set time only 10ms for a
previously tuned frequency.
Simply connect the automatic tuner to the trx
and the antenna and forget it! The transceiver
will always 'see' a well tuned antenna. In order
to optimize the performance it is recommendatory
to install the tuner directly at the antenna
feed point. This is an ideal set-up for all
mobile applications - never again exchange
tuning coils when changing bands or frequencies!
The automatic antenna tuner offers an excellent
solution for hams with restricted space for base
station antennas since it is almost anywhere
possible to throw a wire over a tree or mast.
The SGC tuners are built into a waterproof case
for easy installation outside directly at the
antenna base. DC operating range is 10-18V at 1A
current drain.

3-200 Watt PEP, 40x30x7,5 cm |
654.00 |
Mini Smartuner for max. 100 watt SSB/ 40 watt CW, frequency range 1.8 to 60
MHz, dimensions only 23x18x4 cm incl. case! SMD technology based on 4-layer PCB
results in extreme miniaturization. Economy model with reduced number of tuning
elements compared to the 'big brothers'; NOT suited for 100 watt CW/RTTY or FM
operation!
Small control box featuring the following control capabilities for SG-230,
SG-237 and SG-239:
- Blocking of the automatic tuner function in order to avoid
re-tuning in tunnels or in the vicinity of large metal masses
(truck, bridge etc.)
- Reset, initiates a re-tune process
- Operational status indication of the tuner by means of an
LED (e.g. tuning ready)

Used to supply power to antenna tuners or amplifiers or for remote control of
solenoids over the coax cable. Usually a pair of these Bias-Ts is used, one in
the shack to source the DC power, one at the remote end (DC sink).
The MFJ-4117 switch provides an additional switch to interrupt the power supply.
Frequency range 1-60 MHz, max. 1500Watt or 50V / 1Amp. Supplied with connection
cable.
