Dual-band RP-SMA antenna

The Rfwel Engineering RFWRD2435RPS is a flexible rubber-duck antenna with an RP-SMA male connector. It covers 2.3-2.7 GHz and 3.3-3.9 GHz for Wi-Fi, LTE and CBRS applications. Indoor use suits fixed or mobile devices needing a direct replacement antenna.

Gain stability across bands

Gain measures 2.3 dBi on the lower band and 2.7 dBi on the upper band. The tilt-and-swivel hinge keeps the radiator oriented without stressing the connector during extended sessions. Performance stays consistent across the stated ranges rather than peaking only in short bursts.

RP-SMA connector limits

The reverse-polarity SMA plug mates only with RP-SMA female ports on the host device. It does not fit standard SMA jacks, so installers must verify the port type before purchase. Buyers needing a different connector or outdoor-rated housing cannot use this model.

Questions about this item

Does the antenna generate heat or draw power during continuous 24/7 operation?

This is a passive antenna with no internal electronics, so it produces no heat and consumes no power regardless of how long it runs.

What connector must the host device provide for the RP-SMA male plug on this antenna?

The device needs an RP-SMA female antenna port; the antenna mates directly with that connector.

Will this antenna work with older Wi-Fi gear that only supports the 2.4 GHz band?

Yes, the 2.3-2.7 GHz range covers the 2.4 GHz band, so legacy 2.4 GHz equipment can use the antenna.
