Details

The Alpha 1A is a slim, low profile, T-Bar antenna. With its thin shaped design, measuring 104 x 10.8 x 4mm, this antenna will mount discreetly onto most surfaces, whether that is on top of an energy meter or on the side of telemetry equipment, this antenna will suit a variety of environments and applications. Supplied with an adhesive base, the Alpha 1A is perfect for quick and simple installations onto a number of different surface materials such as: metal, glass, wood and plastic. More so, the use of an adhesive base takes away the need to drill holes or apply adhesive substances - simply ‘peel & press’ the antenna into its desired position.

Optimised for use on all 4 GSM / GPRS frequencies, it also offers 3G, WiFi & ISM functionality for mobile broadband users

The Alpha 1A is tuned to quad band GSM / GPRS, 2G, 3G / UMTS, WiFi & the 868Mhz and 915MHz ISM frequencies, and performs to high level on each of these frequency bands. Its superior dipole design is the secret behind this compact antenna achieving high levels of gain across a wide operating frequency range. Furthermore, having this wide operating frequency range allows for worldwide cellular applications over the quad band GSM / GPRS & 2G networks and also high data transfer rates via 3G / UMTS. The Alpha 1A achieves a respectable peak gain of 3.8dBi, providing good signal reception/transmission which is further supported by its superior T-Bar dipole design.

The Alpha 1A is supplied, as standard, with a 1 metre or a 2.5 metre RG174 coaxial cable, terminated with an SMA male connector. Custom cable lengths and alternative connector types can be supplied for volume requirements.
