The Delta 5A is a direct connect stubby antenna measuring 100mm in length. It is a ¼ wave, helically wound, omni-directional antenna dedicated to 868MHz. With a centre frequency of 868MHz, this antenna resonates on 868MHz that is far more focused than wide band antennas, such as quad band GSM, providing far superior performance. Common applications for ISM antennas are low power short range applications such as: wireless sensory monitoring, street light control, smart metering and security systems, just to name a few.
The bottom of the antenna and the connector are 'flush' with one another, in other words, there is no 'skirt' or over-hang. This antenna can however be built with a skirt to meet the needs of those who require the antenna to sit flush to the mounting surface.
The Delta 5A is supplied with a BNC male connector and can be built with a connector of your choice with volume only orders.
