Does your HF rigs automatic tuner have limited range? Cant auto-tune your antenna on all bands? Have to pretune your antenna with a manual tuner before your automatic tuner will work? Vectronics latest innovation greatly extends the matching range of your automatic antenna tuner -- you can match nearly any antenna automatically!
Vectronics new AutoTuner Extender transforms your antenna impedance -- up or down by as much as 10 times! Puts nearly any antenna to the matching range of your automatic tuner. 
Its easy to use. Just bypass your auto-tuner and turn the VEC-514 knob for minimum SWR. Thats it -- youre ready to auto-tune. Never manually pre-tune with an external tuner again!
By transforming your antenna impedance so your tuner can be used in a low Q mode, you can handle more power without arcing your tuning capacitors. It also extends the range of manual antenna tuners. You can use any transceiver from 160 through 10 Meters with up to 300 Watts.
An OFF position grounds your antenna to bleed off static and protect your receiver. OFF also connects your transceiver to an external dummy load for safety. The VEC-514 also has a bypass position.
VEC-514 is a heavy duty, wide band, wide range, impedance transforming device. It has been carefully designed for flattest frequency response and lowest loss.

VEC-514 AutoTuner Extender  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.

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.
