L14204 900 MHz 0 dBd 1/2 Wave Omnidirectional Antenna with RPSMA Connector


The 14204 is a 0 dBd gain 1/2 wave antenna with an RPSMA (reverse polarity 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 RPSMA antenna jack, such as the RF401A. 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.

Additional Compatibility Information

The 14204 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 14204 can only be directly connected to a radio product or cable with an RPSMA jack. Adapters such as pn 28477 and pn 18686 can be used to adapt this antenna to an RF connection other than RPSMA.
