USING THE ANTENNA FOR TRANSMITTING

For transmitting, you must set the antenna length as close as possible
to the transmitting frequency's 1/4 wavelength.  This ensures the best
possible transmission by use of the proper standing wave ratio.

Caution:  When you use the antenna for transmission, you must always
          collapse the section located just above the loading coil.  If
          you do not, you might damage the antenna and/or your radio.

To calculate the proper length for a 1/4 wavelength transmitting antenna,
use the following formula:

2834/Freq. in MHz=Antenna Length in Inches

   Example: 2834/147 MHz=19.3Inches

Caution:  When you use the antenna for transmitting, you must calculate
          the 1/4 wavelength and adjust the antenna length accordingly.
          If you do not do this, you can damage your transmitting
          equipment due to an improper standing wave ratio.
