Right antenna for the job

This Rfwel Infra rubber duck antenna is built for 5G NR, 4G LTE, CBRS and IoT devices that need a compact replacement. It suits engineers, installers and hobbyists who want a single antenna covering a very wide frequency span without swapping parts.

Frequency range decides fit

The antenna operates from 615 MHz up to 7150 MHz, covering low-band cellular through mid-band 5G and unlicensed spectrum in one whip. If your radio works outside this window the antenna will not perform, so match the device's operating band before buying.

Simple SMA-Male twist-on

Installation is a hand-tight turn onto any SMA-female jack; no tools, soldering or adapters are required. The only common issue is confusing SMA with the similar-looking RP-SMA connector, so verify the jack gender and polarity on your equipment first.

Questions about this item

What does the 5 dBi gain actually do for my 4G or 5G signal in practice?

The 5 dBi figure means the antenna focuses energy more than a basic dipole, giving roughly three times the effective radiated power in its main direction, which can improve range and data rates for 4G LTE, 5G NR and CBRS links.

The SMA-Male connector — does it fit standard SMA-Female ports on routers and modules?

Yes, the SMA-Male plug mates directly with any standard SMA-Female jack found on most 4G/5G routers, USB modems and IoT gateways, so no adapter is needed.

Will the rubber duck body clear the casing on a compact USB modem or router?

The flexible rubber duck design bends to avoid obstruction, and the SMA-Male base adds only the connector length, so it fits tight spaces on USB dongles, indoor routers and small IoT enclosures.
