19512 900 MHz 0 dBd 1/2 Wave Omnidirectional Antenna with SMA Connector

Overview

The 19512 is a 0 dBd gain 1/2 wave antenna with an SMA connector and articulating base. It is designed for use with radios operating at 900 to 930 MHz. It is typically used with one of our 900 MHz radio products with an SMA antenna jack, such as the RF450. This small, low-cost antenna is typically used in applications where space is constrained and antenna gain is not required to maintain a strong RF link. 

Note: The yellow stripes on the antenna indicate that this antenna operates with a center frequency of 916 MHz.

Detailed Description

The 19512 is a 0 dBd gain 1/2 wave center-fed dipole antenna with an SMA male plug connector. It has an omnidirectional radiation pattern and a center frequency of 916 MHz. The articulating base allows the antenna to tilt 90 degrees and rotate 360 degrees. The antenna’s internal counterpoise eliminates external ground plane dependence. The internal O-ring seal on the connector improves the antenna's ruggedness when used in harsh conditions.

Note: The yellow stripes on the antenna indicate that this antenna operates with a center frequency of 916 MHz.

Compatibility

The 19512 covers the frequency bands used by some of our spread-spectrum radios operating in the 900 MHz range. Because it has an SMA plug connector, the 19512 can only be directly connected to a radio product or cable with an SMA jack, such as the RF450. An adapter is required to connect this antenna directly to a radio or coaxial cable with an RPSMA jack.
