Product Brief ANT-868-MHW 868 MHz Helical Dipole LPWA Antenna MHW series antennas are durable remote-mount adhesive-backed dipole antennas that can be attached permanently to a variety of non- conductive surfaces such as windows, drywall, ceiling tiles, and most plastic surfaces. Providing excellent performance for low-power, wide-area (LPWA) wireless applications, the MHW series antennas are available with either, 2.0 m (78.7 in) or 4.6 m (181.1 in) of RG-174 coaxial cable terminated in an SMA plug (male pin) connector. Features Applications Performance summary Low-power, wide-area (LPWA) applications VSWR: 1.3 LoRaWAN Peak Gain: 4.0 Sigfox Efficiency: 54% Remote sensing, monitoring and control Omnidirectional pattern Security systems Rugged & damage-resistant Industrial machinery Durable adhesive backing Internet of Things (IoT) devices Available with 2.0 m or 4.6 m of RG-174 coaxial cable SMA plug (male pin) connector Ordering Information Part Number Description ANT-868-MHW-SMA-L 4.6 m (181.1 in) RG-174 coax cable terminated in an SMA plug (male pin) ANT-868-MHW-SMA-S 2.0 m (78.7 in) RG-174 coax cable terminated in an SMA plug (male pin) Available from Linx Technologies and select distributors and representatives.ANT-868-MHW Product Brief Electrical Specifications ANT-868-MHW 862 MHz to 876 MHz VSWR (max) 1.3 Peak Gain (dBi) 4.0 Average Gain (dBi) -2.8 Efficiency (%) 54 Polarization Linear Radiation Omnidirectional Max Power 10 W Wavelength 1/2-wave Electrical Type Dipole Impedance 50 Cable 2.0 m (78.7 in) or 4.6 m (181.1 in) of RG-174 coaxial cable Connection SMA plug (male pin) ANT-868-MHW-SMA-S: 44.0 g (1.60 oz) Weight ANT-868-MHW-SMA-L: 76.5 g (2.70 oz) Dimensions 138.0 mm x 15.5 mm x 9.2 mm (5.43 in x 0.61 x 0.36 in) Operating Temperature Range -20 C to +70 C VSWR Figure 1 provides the voltage standing wave ratio (VSWR) across the antenna bandwidth. VSWR describes the power reflected from the antenna back to the radio. A lower VSWR value indicates better antenna performance at a given frequency. Reflected power is also shown on the right-side vertical axis as a gauge of the percentage of transmitter power reflected back from the antenna. 5 40 4 30 3 20 2 10 1 0 858 860 862 864 866 868 870 872 874 876 878 Frequency (MHz) Figure 1.
