New rubber duck antennas offer small size and big reach

L-com, an Infinite Electronics brand, has added a new line of rubber duck antennas. These omnidirectional antennas are compact and flexible for simple installation and adjustment, ideal for low-power applications and are cost-effective.

They come in three main frequency bands of 2.4GHz, 433MHz and 916MHz. The 2.4GHz antennas are commonly used to extend the range of Wi-Fi routers, improve the signal strength of Bluetooth devices and improve the function of cordless telephones. The 433MHz antennas are a good match for industrial remote controls, tyre pressure monitoring systems and keyless entry systems. The 916MHz antennas extend the reach and reliability of short-range radio applications, such as wireless alarm systems and industrial telemetry.

These new rubber duck antennas are small and lightweight, making them easy to carry, store and fit into tight spaces without sacrificing performance or aesthetics. Some are less than an inch tall. They are simple to install, typically attaching to devices utilising screws or basic connectors that do not need special tools or expertise. Their tilt/swivel flexibility permits them to be bent and adjusted for optimal positioning. Their omnidirectional radiation pattern delivers consistent signal coverage in all directions, minimising dead spots.

The new flexible antennas are durable to minimise maintenance costs and downtime associated with antenna replacements. Their operating temperature range is minus-40F to +140F (-40C to +65C).

Applications for the company’s new rubber duck antennas include Wi-Fi, Bluetooth, IoT, both fixed and mobile devices, LPWAN, ISM, LoRaWAN, Sigfox, Weightless-P, Wi-Fi HaLow, Zigbee and more.

“Our new line of rubber ducks helps round out our already extensive selection of compact omnidirectional antennas,” said product line manager Kevin Hietpas. “The newly designed mini antennas with solder posts are perfect for direct-to-board applications.”
