The Alpha 14 is Siretta’s MOST COMPACT adhesive antenna, with a slim and extremely low profile design, measuring at an impressive 33.5 x 39.9 x 3mm. It can sit almost unnoticed on top 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 14 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 14 is easily implement due to its adhesive based mounting. The user simply peels the cover off of the adhesive padded based a places the antenna on the surface it is to remain attached to.

The Alpha 14 is tuned to quad band GSM / GPRS, 2G, 3G / UMTS and the ISM frequencies 868MHz & 915MHz, making this antenna a very mainstream performer. Its wide operating frequency band allows for worldwide cellular applications over the quad band GSM / GPRS & 2G networks and also high data transfer rates via 3G / UMTS. In addition, the Alpha 14 is suitable for use with ISM based applications that operate on either 868Mhz or 915MHz. The Alpha 14 achieves a respectable peak gain of 2.7 dBi from a small form factor, making this antenna Siretta’s most recommended Alpha for GSM / 3G / ISM applications where space optimisation is at a premium.

The Alpha 14 is supplied, as standard, with a 2.5 meter RG174 coaxial cable, terminated with an SMA male connector. Custom cable lengths and alternative connector types can be supplied for volume requirements.
