Wideband Replacement Antenna

This rubber duck antenna covers 615 to 4200 MHz with up to 4 dBi gain and an SMA-Male connector. It is built as a direct replacement for 5G NR, 4G LTE, CBRS, IoT and Wi-Fi devices that use the same fitting. The omnidirectional pattern suits fixed or mobile installations where a single wideband element is preferred. New condition ensures full electrical performance from the first use.

Installers needing one antenna for multiple bands

Technicians maintaining mixed fleets of cellular routers, IoT gateways or Wi-Fi access points will appreciate the broad coverage. Buyers who require higher gain for long-range point-to-point links should look at directional alternatives. Anyone whose equipment uses a reverse-polarity SMA or a different connector type cannot use this unit.

SMA-Male connector and 615-4200 MHz range

The SMA-Male plug and the stated frequency span are the only specifications that determine fit and function. Verify that the host device presents a standard SMA female jack and operates within these limits before purchasing. No other parameter in the data overrides this compatibility check.
