Installing an Antenna
Revolve the movable part of the metal SMAJ interface with gentle force until it cannot be
revolved, in which state the outer thread of the antenna connection cable is invisible. Do not
wring the antenna with force by grabbing the black plastic cover.

Note
⚫
IG502 supports dual antenna: ANT antenna and AUX antenna. The ANT antenna sends and
receives data. The AUX antenna only increases the antenna signal strength and cannot be
used independently for data transmission.
⚫
Only the ANT antenna is used in normal cases. It is used with the AUX antenna only when
signal is poor and signal strength must be improved.
