915MHz Spring Antenna for RF95 LORA Module

This 915MHz spring antenna is a compact, low-cost solution for adding reliable RF connectivity to LoRa-based projects using the RF95 module and similar 900MHz transceivers. Its helical spring design packs an electrically effective length into a tiny footprint, making it ideal for space-constrained enclosures where a full-size whip or fiberglass antenna simply won’t fit. The antenna solders directly onto the PCB, giving a permanent, low-profile connection without the bulk of a connector-mounted alternative.

Tuned specifically for the 915MHz ISM band, it pairs naturally with RFM95/RF95-based LoRa transceivers, RFM69 modules, and other sub-GHz radios operating in the 900MHz range, commonly used in LoRaWAN nodes, remote sensor networks, and long-range telemetry projects. With a 50-ohm impedance matching most RF front ends and a gain of 2.15dBi, it delivers dependable performance for typical hobbyist and IoT communication ranges. This antenna is a great fit for makers building LoRa gateways, sensor nodes, weather stations, and any DIY project that needs a small, solderable 915MHz antenna without the cost or size of an external mount option. Its simple two-lead soldering interface makes installation quick, even for those new to RF design.
