Telescoping Antenna (200-0006) Operation Faxback Doc. # 6823
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.
