20 Use of antennas
When listening to SW, CB, FM, AIR, VHF, WB or UHF, pull out the extendable rod
antenna of the RF919 and align its length for best reception. Try
different directions and find a position with the best receiving effect.
Tip: Shorten the extendable rod antenna if the received signal is distorted by very
strong radio interference, resulting in crosstalk.
The below block diagram is intended as a reference to the building blocks of the
RF919 as seen from a technical point of view.
