Magnetic Mount Omni Mobile Antenna: 4 dBi 850-920MHz

  • For LoRa / LoraWAN, Helium, GSM, ZigBee, and any other wireless protocol that uses a frequency in the 850-920MHz band.
  • See all 900MHz Antenna options:  LoRa, Helium, LoRaWAN, GSM, 3G options
  • With 6.5 feet (2-meter) cable to RP-SMA-male or SMA male connector. Compatible with Wireless Access Points & other devices that have SMA antenna jacks.
  • Customizable: with a different length of the cable, or with a different connector type, we can customize this for purchases of large qtys.  Contact customer service.
  • Double-shielded, low-Loss Cable: LMR100-equivalent low-loss cable is of much higher quality than the typical pigtail cables for antennas of this size (typically RG174). The cable color is black.

Magnetic Mount antenna very firmly attaches to metal surface - at a height or position where it can maximize signal strength.

  • Lightweight and portable
  • Put the antenna high or on top of a vehicle for much better signal strength.

Compatibility with wireless standards & applications:

This omni directional antenna's range of frequency band compatibility in the 850 MHz to 920 MHz frequency band range, its low broadband VSWR, and impedance matching to 50 Ohm gear, makes it suitable and compliant for all the above applications.


Gender of RP-SMA is counter-intuitive in two ways:

1.The gender is referring to the connector's pins and not the threads. RP-SMA male has threads on inside.

2. "RP" stands for reverse polarity: The pins are female when they appear to be male, and vice versa. Click here for more details regarding RP-SMA gender determination.

Put the antenna outside and on top of the vehicle where it can pick up more access points. Comes with 1.5 meter (5 ft) pigtail with RP-SMA (male) connector.

Cable is LMR100-equivalent, which is low-loss cable of much higher quality than the typical pigtail cables for antennas of this size (typically RG174). The cable color is black. The higher quality of the cable of this antenna translates into lower loss/better performance. Lightweight and portable. Brand new, high quality connector from ISO 9001 facilities.


  • Frequency: 850~920 MHz
  • Gain: 4.0 dbi
  • Impedance: Antenna, cable and connector are impedance-matched-matched to 50 Ohm gear.
  • VSWR: < 2.0 : 1
  • Maximum Input Power: 50 Watts
  • Dimensions: Length: 10.43 in (265mm). Width of the base: 1.18 in (30mm).
  • Cable Length: 2 meters (6.5 feet). Some "gain" (signal strength) is lost with length of cable (1.27dBi is lost per meter of cable).Therefore the best choice of cable length is the shortest length that meets your needs.
  • Cable type:The cable is a very high quality double-shielded low-loss cable (LMR100 equivalent), which is far superior in quality than the more commonly used cables (RG174, which has one layer of shielding) of a similar diameter.
  • Polarization: Vertical
  • Weight: 1 ounce
  • Beamwidth: H-Plane: 360-degrees: The omni dipole antenna receives and sends signals from 360 degrees all around it.
  • Lead-free and compliant with RoHS and REACH: All of our antenna cables and RF adapters are RoHS compliant and REACH compliant.
  • ROHS & REACH compliant: Heavy metal content and other material content is in compliance with ROHS 3 and REACH (connector and antenna).

RP-SMA and SMA Connector Characteristics:

Data Alliance's high-quality soldered terminations of RP-SMA and SMA connectors with soldering provide a low-loss connection with discontinuities kept to a minimum.


All of our antennas pass QC test before we ship them.
