433MHz 2.5dBi Omnidirectional Folding Antenna

Yes, this antenna is directly compatible with any RF module featuring a female SMA or RP-SMA connector tuned for the 433MHz ISM band, such as the SX1278 (LoRa) or nRF24L01+. Ensure your module's connector type (SMA or RP-SMA) matches the antenna's male pin. The 50-ohm impedance and 433MHz center frequency are optimized for maximum power transfer and range in LoRaWAN and other sub-1GHz telemetry applications.

SMA connectors have a male pin in the plug and a female socket in the jack. Reverse Polarity SMA (RP-SMA) reverses this: the plug has a female socket, and the jack has a male pin. This antenna is supplied with a standard male pin. You must verify your device's port: if it has a center hole (female socket), use an SMA antenna; if it has a center pin (male), you need an RP-SMA variant or an adapter to avoid damage and ensure proper connection.

Screw the antenna connector firmly onto your module's RF port to ensure a solid electrical connection. For omnidirectional coverage, orient the whip vertically. The folding design allows you to adjust the angle if needed, but a vertical position typically provides the most uniform horizontal radiation pattern. Avoid placing the antenna near large metal objects or enclosures, as this can detune the frequency and significantly reduce effective range and signal quality.
