GENERAL INFORMATION
Does your automatic antenna tuner have limited matching range? Can't auto-
tune your antenna on all bands? Do you have to pre-tune your antenna with a
manual tuner?
The VEC-514 AutoTuner Extender

greatly extends your automatic tuner's
matching range. Now you can match nearly any antenna automatically!
The VEC-514 s a heavy duty, wide range impedence transforming device. It has
been carefully designed for the flattest frequency response and the lowest loss.
Vectronic's AutoTuner Extender
   
transforms your antenna impedence -- up or
down -- by as much as 10 times! The VEC-514 puts nearly any antenna into the
matching range of your automatic tuner!
Extend your power range by transforming your antenna impedence so your tuner
can be used in a higher power Low-Q mode. The VEC-514 also extends
manual antenna tuners.
You can use any tranceiver from 160 through 10 meters with up to 300 watts.
INSTALLATION
The VEC-514 connects in-line between your transmitter and antenna. Connect
your transmitters antenna output to the SO-239 connector labeled Transmitter,
and your antenna to the Antenna connector. For maximum protection of your
tranceiver, a 50 Ohm dummy load should be connected to the plug labeled
Dummy Load, and the Ground stud connected to a good RF ground.
OPERATION
The VEC-514 AutoTuner Extender is easy to use! First, bypass your
transmitters auto-tuner. Then, while transmitting at a low output power, adjust
the knob (from position A through G) on the VEC-514 until you see minimum
SWR on your transmitter. Now you're ready to autotune. The Off / Dummy
Load position on the knob protects your tranceiver by connecting it to an
external dummy load, and by grounding your antenna to bleed off static. The
switch position D provides a through connection from your transmitter to your
antenna.
