If the RT20A is left in the same location for a longer period of time
without being dismantled, turn the antenna's elevation angle to
approximately 90° in order to decrease the wind resistance. If the antenna
is dismantled after the sounding, turn the antenna's elevation angle to
approximately 2 or 3 degrees, which makes it easier to detach and set up
the antenna elements.
3. Switch OFF the RT20A power supply.
