The Ebyte TX490-BLG Series is a specialized line of omnidirectional fiberglass antennas optimized for 470MHz and 490MHz Sub-GHz bands. Purpose-built for LoRaWAN, private radio networks, and industrial meter reading (AMR), this series offers reliable gain configurations: 2.0 dBi (120mm) for compact installations and 5.5 dBi (400mm) for high-sensitivity long-range gateways.
Encased in a heavy-duty, UV-resistant fiberglass radome, the TX490-BLG is engineered for permanent outdoor mast mounting. The N-Type Male (N-J) connector ensures mechanical stability and low-loss RF performance, even in high-humidity or high-vibration industrial environments.

Primary outdoor antenna for 470MHz LoRa gateways, ensuring stable connectivity for thousands of nodes.
🏭 Smart Metering (AMR)
Reliable signal backhaul for water and gas meters operating in the licensed or unlicensed 470MHz bands.
🌾 Smart Agriculture
Remote irrigation control and soil moisture monitoring where long-range Sub-GHz penetration is essential.
🏙️ Municipal IoT
Outdoor environmental sensors and smart street lighting controllers requiring weatherproof infrastructure.
Frequently Asked Questions
1. How do I connect the TX490-BLG to an Ebyte E22 or E32 LoRa module?
Since the antenna uses an N-Type Male (N-J) connector, you will need an N-Female to SMA-Male pigtail cable. You can find compatible low-loss RF cables directly at ebyte to bridge the gap between your module's SMA interface and this outdoor antenna.
2. Can I use this antenna with a Raspberry Pi LoRa HAT?
Absolutely. For developers using GitHub open-source LoRaWAN stacks on a Raspberry Pi (like ChirpStack), this antenna provides the professional-grade gain needed for a robust base station. Ensure your Pi enclosure is waterproof or use a long coaxial run to mount the antenna on a roof mast.
3. Why choose fiberglass over a rubber-duck antenna for 470MHz?
Rubber-duck antennas are for indoor use. The TX490-BLG's fiberglass radome is IP67-equivalent, meaning it won't degrade under UV exposure or fail during heavy rain, ensuring your IoT network stays online 24/7 in harsh outdoor conditions.
