The pocket-sized RF1 is designed to check and adjust antennas,feedlines,
and RF networks. It includes a microprocessor,A/D coverters, and a low-power
"transmitter" with 4 digit frequency readout, continuously variable
from 1.2 to 34 MHz in 5 bands.
It measures RF values of true impedance (0-2000 ohms),SWR (1 to 15:1),
C(0-9999 pF), and L (less than 0.04 to 300 uH).
All parameters are read out digitally for highest accuracy.
The RF1 is extremely easy to use. Its large 1/2" LCD display is not washed
out in sunlight..it loves sunlight. And it can cycle between several
measured values so you can watch them together.
L and C are measured
at the RF frequency of interest, not at 1 KHz or 100 KHz as on other meters.
So the effects of stray capacitance, toroid parameters, and other
frequency-dependent factors are taken into account. The RF1 can even
measure the inductance of less than 1/2" (1 cm) of straight wire!
The RF1 is truly pocket size. 4.5 x 2.5 x 1.5 in. The battery pack
on other units is
actually larger than the entire RF1! The RF1 runs off a
single 9 volt battery in a real battery compartment on the
back with a pushoff cover...similar to a TV remote control.A
standard 9 V alkaline battery has a life of about 5 hours,
and can be replaced in seconds. In addition, the unit turns
itself off after about 20 minutes if no buttons are pushed.
(The auto-off feature can be disabled if desired.)
The illustrated instruction manual discusses many applications in
detail, not just instrument operation. Whether you're an expert or
novice, the manual will show you many of the things you can do
with the unit.
Besides its use by Amateur Radio operators, this unit is in use all over
the world at antenna manufacturers, production lines, and laboratories.
