2.2. External Antenna Connection
Screw the antenna enclosed into the SMA antenna connector. Tighten the antenna
connector gently with your hand - never use spanner!
The antenna for direct connection has a sufficient gain for trouble-free operation in
normal conditions. If the GSM signal is poor, in case of voice disturbance, or if you want
to place your antenna separately from SmartGate, you can use an antenna with an
SMA-connector terminated coax cable. The antenna should be mounted vertically.
For antenna and cable parameters see the “Technical Parameters“.
2.3. SIM Card Installation
Open the SIM card holder on SmartGate’s backside, insert the SIM card and close it
properly. Select the required GSM provider and SIM card services, such as call
forwarding, call barring, preferred networks, SMS service centre, etc. in your mobile
phone before inserting your SIM card in SmartGate.
