15731 900 MHz 0 dBd 1/4 Wave Omnidirectional Antenna with RPSMA Connector

Overview

The 15731 is a 0 dBd gain 1/4 wave helical antenna with an RPSMA connector designed for use with radios operating at 900 to 935 MHz. The 15731 is typically used with one of our 900 MHz radio products with an RPSMA antenna jack, such as the RF401A and RF411A. 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 stripe on the antenna indicates that this antenna operates with a center frequency of 916 MHz.

Omnidirectional antennas pick up signals from all directions. (That is, they don't need to be pointed directly at the source of the signal to pick it up.)

Additional Compatibility Information

The 15731 covers the frequency bands used by some of our spread-spectrum radios operating in the 900 MHz range. Because it has an RPSMA plug connector, the 15731 can only be directly connected to a radio product or cable with an RPSMA jack. This includes, but is not exclusive to, the RF401A, RF411A, CR206X, CR211X, AVW206, and AVW211. Adapters such as pn 28477 and pn 18686 can be used to adapt this antenna to an RF connection other than an RPSMA.
