3.3.3.2 Outdoor 2G/3G/4G Directional Antenna
The Outdoor 2G/3G/4G directional Antenna (3HE12344AA) features a frequency
range of 698 to 960 MHz and 1710 to 2700 MHz and nominal gain of 6 dBi at 698 to
960 MHz and 8 dBi at 1710 to 2700 MHz. The impedance is 50 Ω. See Outdoor 2G/
3G/LTE Directional Antenna Specifications and Outdoor 2G/3G/4G Directional
Antenna Installation Overview for more information.
On the back of the antenna are two N-Type (female) connectors. The antenna is
waterproof, vented, and rated at IP67 for indoor or outdoor use.
The antenna is shipped with a heavy-duty articulating mounting bracket that supports
horizontal polarization, vertical polarization, or a 45° diagonal slant. The bracket can
be fixed to a mast measuring 1.63 to 2.3 in. (41.4 to 58.4 mm) O.D. using pipe
clamps. Pipe clamps and installation instructions are included with the antenna.
3.3.3.3 Indoor LTE Omni-directional Antenna
The indoor LTE omni-directional Antenna (3HE12371AA) is a dipole terminal
antenna with a hinged SMA (male) connector suitable for direct mount on the
7705 SAR-Hm in an indoor facility.
The antenna operates in a dual frequency of 698 to 960 MHz and 1710 to 2690 MHz,
a nominal impedance of 50 Ω. See Indoor LTE Omni-directional Antenna
Specifications and Direct-mounting the Indoor LTE Omni-directional Antenna for
more information.
3.3.3.4 LTE Surge Protectors
The LTE surge protectors are designed to offer sufficient protection against lightning
surges and are highly recommended when installing outdoor antennas.
Nokia offers three variants, which are N-Type (female to female) for indoor to outdoor
applications, and N-Type (female to male) or 4.3-10 (male to female) for
7705 Outdoor Enclosure applications. The frequency range is from 698 MHz to
2700 MHz.
