900 MHz 4dBi Magnetic-Mount Omni Antenna
Magnetic Mount Omni Mobile Antenna: 4 dBi 850-920MHz
- For LoRa / LoraWAN, Helium, GSM, Wi-Fi HaLow, ZigBee, and any other wireless protocol that uses a frequency in the 850-920MHz band.
- See all 900MHz Antenna options: LoRa, LoRaWAN, GSM, 3G Wi-Fi HaLow 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 quantities. 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.
Compatible with Wi-Fi HaLow devices, as are all antennas in our Wi-Fi HaLow Antennas subcategory
- Wi-Fi HaLow Antennas and LoRaWAN access points.
- LoRa / LoRaWAN.
- 900MHz ISM Band. Can also be made to operate on other VHF and UHF frequencies within the ISM frequency bands .
- Non Line of Sight (NLOS): 900 MHz band is best for passing through trees and forests.
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 DETERMINATION:
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.

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.
TEST RESULTS for FREQUENCY RANGES:
The antenna exhibits stable performance over the frequency range from 900 to 1000 MHz, with moderate impedance matching and consistent behavior across the band. S11 measurements show VSWR values ranging approximately from 1.48 to 2.41, with Return Loss levels close to −14 dB at the lower end of the band and around −7.7 dB toward the upper end. This indicates acceptable power transfer with controlled reflection losses.
| Frequency range | Assessment | Rating | Compatible technologies |
|---|---|---|---|
| 0.90–1.00 GHz | Good | ★★★ | Cellular 900 MHz bands (GSM/EDGE 900), LTE Band 8 (partial overlap), regional/private sub-GHz cellular systems, ISM/IoT links around 915 MHz (LoRa/FSK telemetry), UHF RFID systems (regional 902–928 MHz), industrial telemetry and monitoring links, and wideband sub-GHz communication platforms near 1 GHz. Impedance matching improves toward the lower end of the band, with VSWR ranging from ~1.48 (≈900 MHz) to ~2.41 (≈1000 MHz) and Return Loss from approximately −14.2 dB to −7.7 dB, providing acceptable power transfer with moderate reflection losses |
