14203 900 MHz 3 dBd Omnidirectional Antenna without Mounting Hardware


The 14203 is a high gain (3 dBd) omnidirectional antenna for our 900 MHz spread-spectrum radios and dataloggers. It does not include antenna mounting hardware and is intended for customers who want to construct an antenna mounting bracket that fits their specific application. Customers who want antenna mounting hardware should purchase the 14221, which provides a 3 dBd omnidirectional antenna with antenna mounting hardware.
