MFJ 993 B, IntelliTuner Automatic Antenna Tuner

Automatically tunes unbalanced/balanced antennas,
ultra fast. It has 20,000 memories, an antenna
switch, and is an efficient L-network. You can
select 300 Watts (6-1600 Ohms) or 150 Watts
(6-3200 Ohms). It covers 1.8-30 MHz, and includes
a 4:1 current balun, a Cross-Needle and Digital
SWR/Wattmeter, and an audio SWR meter. It has
a backlit LCD display, and a remote control port
for interfacing with your radio.

When you transmit, the MFJ-993B automatically
tunes for minimum SWR and remembers your
frequency and tuner settings. The next time
you operate on that frequency and antenna,
these tuner settings are instantly restored
and you’re ready to operate in milliseconds!

The MFJ-993B is a compact 10W x 2¾H x 9D inches,
and uses 12 –15 V DC at about an amp.
