900MHz ISM Band Directional Yagi Antenna 11 dBi with Weatherproof Applications.
- A Directional Yagi design radiates a signal pattern in the direction in which the antenna is pointed. See the radiation pattern in the images. Directional antennas have less interference than omnidirectional antennas because they focus the signal in a single direction, thereby eliminating much of the signal noise.
- For LoRa / LoraWAN, Helium LongFi, GSM, ZigBee, Wi-Fi HaLow and any other wireless protocol that uses a frequency in the 850-920MHz band.
- See all 900MHz Antenna options: LoRa, Helium, LoRaWAN, GSM, and 3G options
- Data Alliance's high-quality soldered terminations of Type-N connectors with soldering provide a low-loss connection with minimal discontinuities.
- Nickel-plated brass body for enhanced corrosion resistance: Nickel plating is the most weather-resistant, corrosion-resistant metal plating.
Mount Options: See our mount options for antennas with an N-connector (Type-N connector)
Compatibility with wireless standards & applications:
- LTE / 4G & GSM /3G: Broadband design for 4G / LTE and 3G / GSM systems: 4G networks
- All antennas in our Wi-Fi HaLow Antennas subcategory are compatible with Wi-Fi HaLow devices. They include LoRaWAN access points.
- LoRa / LoRaWAN.
- 900MHz ISM Band can also 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.
- IoT wireless & M2M: Compatible with many machine-to-machine communication applications, remote monitoring, and telemetry applications using LTE-m, 4G / LTE, and 3G / GSM. (Compatible because it is vertically polarized ).
This directional Yagi antenna's range of frequency band compatibility in the 824 MHz to 960 MHz frequency band range, it's very low broadband VSWR at ≥1.5, and its impedance matching to 50 Ohm gear make it suitable and compliant for all the above applications.

TEST RESULTS for FREQUENCY RANGES:
The antenna exhibits very favorable performance over the frequency range from 860 to 952 MHz, with impedance matching clearly optimized toward the upper end of the band. S11 measurements indicate an excellent matching point around 951.8 MHz, where the VSWR decreases to approximately 1.11 and the Return Loss reaches about −25.8 dB, demonstrating very efficient power transfer and minimal reflection losses.
Note: The antenna is equipped with an N-Female connector. For measurement and characterization purposes, an N-Male to SMA adapter was used to connect the antenna to the VNA antenna analyzer during testing. This adapter is also available from Data Alliance.
| Frequency range | Assessment | Rating | Compatible technologies |
|---|---|---|---|
| 0.860–0.952 GHz | Very good | ★★★★ | Cellular 850/900 MHz bands (GSM 850/900), LTE Band 5 and Band 8, NB-IoT / LTE-M deployments in the 850–900 MHz range, ISM/IoT links around 915 MHz (LoRa, FSK telemetry), UHF RFID systems (regional 860–960 MHz), industrial telemetry and monitoring systems, and wideband sub-GHz wireless communication platforms. Optimized impedance matching toward the upper end of the band, with a clear resonance around 951.8 MHz, where VSWR reaches approximately 1.11 and Return Loss approaches −25.8 dB. Across the full band, impedance matching remains stable, ensuring efficient power transfer with minimal reflection losses. |
N-type female Connector Characteristics and Details: Durable, weatherproof connection
- Nickel-plated brass body for enhanced corrosion resistance: Nickel plating is the most weather-resistant, corrosion-resistant metal plating.
- Our N connectors, known for their reliability, consistently deliver high performance from 900MHz to 12.5 GHz. N-Female diameter is 0.620 inches (1.57 cm). N-male inside diameter is 0.620-inch (1.57 cm)
- N-connector gender is counter-intuitive.
- N-Type connectors are the largest RF connector types, usually found on large antennas, especially for outdoor use.
Our N-Type connectors, meticulously designed with threaded coupling mechanisms, are fully interchangeable with N-Type connectors made to the MIL-C-39012 specification. These connectors are a staple in all systems where excellent RF and mechanical performance is critical.
Common Applications
- Cellular signal boosting (4G/LTE/5G)
- IoT Gateways and Backhaul
- LoRa / LPWAN Systems
- WiFi Bridging (2.4 or 5.8 GHz if designed for it)
- SCADA / Telemetry / M2M Communications
This kind of antenna is typically used in professional wireless installations where directional signal strength and longer range are desired
