3.4 Antenna Connector
The antenna connector allows transmission of radio frequency (RF) signals between the modem and an
external customer-supplied antenna. The modem is fitted with a 50
Ω
, SMA female coaxial jack. It is IP65
protected.
The MTX-IND-V2 can also accommodate internal antennas. Just unplug the U.FL connector from Cinterion
TC65i and plug the U.FL connector into an internal antenna. We recommend
EAD
QUINTUS but other
models are available.
The external antenna must be matched properly to achieve best performance regarding radiated power,
modulation accuracy and harmonic suppression.
It is possible to operate with the external antenna and the internal antenna at same time, a special SMA
switch connector must be used (given on request). When the external antenna is screwed, the internal one
is disconnected.
3.5. SIM card reader
The MTX-IND-V2 Terminal is fitted with a SIM card reader designed for 1.8V and 3V SIM cards.
