Alpha 3: Quad band GSM & 3G (EOL part Inventory stock only)

Alpha 3A: Quad band GSM, 3G, ISM & WiFi

The Alpha 3A is a slim, low profile, blade antenna. Its compact and stylish design means this antenna will fit 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 a 3M adhesive base, the Alpha 3A 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.

The Alpha 3A is tuned to quad band GSM/GPRS, 3G/UMTS, WiFi/WLAN & the 868/915MHz ISM frequencies, making this antenna a very versatile performer. Its 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. Aside from this, the Alpha 3A can be used solely for WiFi / WLAN or ISM purposes, such as improving a wireless router’s signal transmission/reception or for your short range license free application.

The Alpha 3A is supplied, as standard, with a 3 meter RG174 coaxial cable, terminated with an SMA male connector. Custom cable lengths and alternative connector types can be supplied for volume requirements.
