MFJ-801 FIELD STRENGTH METER

The MFJ-801 Field Strength Meter is ideal for reading relative field strength
from your antenna. It is a compact unit that fits in the palm of your hand and can
be taken anywhere. The best part of using it is that you now can tell if your
antenna is radiating or not by simply holding the unit near your antenna and
adjusting the sensitivity. Also, by taking measurements, you can find out
relatively how strong your antenna field i s .

Operation

The MFJ-801 Field Strength Meter is very simple to use. It requires no power
because your antenna field provides the power necessary to run the meter.
Simply raise the single whip antenna on your unit, stand several feet away, and
adjust the sensitivity knob on the front, it’s that easy. You want to ensure that
the whip antenna is parallel with the polarity of the antenna you are reading.
Also, ensure that the ground screw on the side of your MFJ-801 Field Strength
Meter is in good contact with your hand (you provide the ground for the unit.)
Now you can read the relative field strength of your antenna.
