EM-900/2400 (Dual-Feed ISM)

Dual-Feed ISM Embedded Antenna


The EM-900/2400 provides separate 863–928 MHz and 2.4 GHz feeds on one flexible internal antenna strip.

  • Provides dedicated 2 dBi feeds for 863–928 MHz and 2400–2500 MHz.
  • Maintains 18 dB low-band and 7 dB high-band isolation between the two connections.
  • Uses two six-inch RG-178 cables terminated with U.FL connectors.
  • Fits narrow internal spaces with a 0.60-inch-wide flexible element.

Customization: Cable type, cable length, and connectors can be configured for specific installation requirements.

Product Description

The EM-900/2400 combines two independently connected ISM ranges on one flexible internal element. One feed covers 863–928 MHz for compatible sub-GHz devices, while the second covers 2400–2500 MHz for 2.4 GHz radios.

This separation lets a device route each antenna connection to the appropriate radio. Mounting tape secures the thin circuit inside an ABS or similar enclosure.

Ideal applications:

  • Dual-radio IoT devices
  • Sub-GHz and 2.4 GHz gateways

Example Model Configurations: EM-900/2400-0R0R-6
