MFJ-934 combines a versatile antenna tuner with an artificial ground.
It turns a random wire into an effective antenna that works. it's great for
traveling, emergency or as a makeshift antenna.
You get all the best features of the MFJ-941E Cross-Needle Antenna Tuner and
the MFJ-931 Artificial Ground in a single compact 10 5/8W x 3 1/2 H x 8 D inch
cabinet -- and the MFJ-934 cost less.
You get a 300 watt full featured, general purpose antenna tuner that covers
1.8 - 30 MHz. It has a two range, lighted Cross-Needle Meter that lets you
read SWR, forward and reflected power all in a glance and a 4:1 balun for
balanced lines. Plus you get an efficient airwound inductor, special high
current/voltage 12 position inductor switch and two 1000 volt air-variable
capacitors. It tunes all types of antennas and feedlines including random
wire, coax and balanced lines.
The MFJ-934 is unique because it has a built-in artificial ground. A ground
matching knob lets you switch in inductance to bring an attached wire to a low
impedance current point to form an artificial ground. A push button lets you
use the cross-Needle Meter to monitor for maximum ground current.
With an artificial ground to work against, you'll be surprised to see how well
a random wire can work. Don't be surprised if you can work the world without
hours of calling CQ. When you don't need the artificial ground feature, you
can use the MFJ-934 as a full featured tuner. |
