DELTA 1 & DELTA 2 Quad Band GSM/GPRS Stubby Antenna, Siretta The DELTA 1 and DELTA 2 families are direct connect, stubby antennas tuned to the quad band GSM / GPRS and 3G frequencies. DELTA 1 antennas have a straight connector and DELTA 2 have a right angled connector.

The C versions of both families are tuned specifically to quad band GSM / GPRS and the A versions add in 3G / UTMS and ISM bands (868 MHz / 915 MHz).

The DELTA 1 and DELTA 2 ranges offer small, cable-free antenna options that are ideal for use with wireless terminals and modems within the M2M industry. Attaching directly to antenna ports simplifies installation. These antennas are commonly used for applications such as: car park metering, utilities metering, road traffic monitoring and other M2M applications communicating using GSM, 3G or ISM frequencies.

They are tuned generally to quad band GSM / GPRS, 3G / UMTS and the 868 MHz and 915 MHz ISM frequencies. Each version is tuned differently so you can optimise for your application.

The wide operating frequency band allows for worldwide cellular applications over the quad band GSM / GPRS networks and also high data transfer rates via 3G / UMTS.
