security alarm phone,etc.(Special statement:it is strictly prohibit-
ed to interfere with other lllegal purposes such as remote control
signals,offenders are responsible for themselvesl)
ABOUT REMOTE DISTANCE:
The remote control distance we are talking about is the maximum
decodable distance measured on a straight line on open ground
under rated conditions when the transmitter/receiver modules
work alone,and are equipped with a quarter-wavelength metal an-
tenna,and work in a vertical state under rated conditions. Working
in the UHF frequency band,electromagnetic waves propagate
along a straight line,and obstacles will be greatly attenuated,and
the remote control distance will be significantly shortened. There-
fore, when usingit,try to avoid obstacles ortry to raise the anten-
na as much as possible.
