GNSS IP67 Waterproof Positioning Antenna
The Maswell Communication Tech. GNSS antenna delivers IP67-rated waterproof protection for outdoor positioning. It covers GPS L1, GLONASS G1, Galileo E1 and BeiDou B1 bands with right-hand circular polarisation. A 5 dBic zenith gain and 28 ± 2 dB active gain support reliable satellite reception. The ASA radome resists UV and harsh weather across a -40 to +85 °C range.
SMA Connector with 3 Metre RG174 Cable
The antenna terminates in an SMA male connector on a 3 metre RG174 coaxial cable. This cable type introduces higher attenuation than thicker alternatives, so cable length should be kept to the supplied 3 metres for best signal integrity. The 50 ohm impedance matches standard GNSS receiver inputs. Mounting uses both screw holes and 3M adhesive for flexible installation.
Active Gain and Voltage Requirement
The integrated low-noise amplifier provides 28 ± 2 dB gain with a 1.5 dB noise figure while drawing power from a 3 to 5 V DC supply. Receivers must supply this voltage on the centre conductor; passive-only inputs will not power the antenna. The 3 dB maximum axial ratio maintains polarisation purity across the 1561.098 to 1602 MHz band.

Questions about this item
Which mounting method should I choose between screw and 3M adhesive for the Maswell GNSS antenna?
Both screw and 3M adhesive are included; screw gives a permanent fix on flat surfaces while the adhesive allows quick installation without drilling.
What does the 28 dB gain figure mean when the antenna is connected to a GNSS receiver?
The 28±2 dB active gain amplifies weak satellite signals at the antenna, improving lock time and position accuracy in obstructed environments.
How does the SMA connector and RG174 cable affect signal loss in practice?
The 3 m RG174 cable with SMA male connector adds modest attenuation; keep the run short and avoid sharp bends to preserve the 28 dB gain.
