The Cyfre CA-819 Direct Connect (inline) Bi-directional Amplifier improves RF coverage in areas with no signal or low signal strength. The unit amplifies both 800MHz and 1900MHz cellular and PCS signals  

Works with all Cellular/PCS Service Providers except iDEN (Nextel/Southern LINC/Mike) and 1700MHz AWS (T-Mobile US 3G)

How the unit functions:

The 800MHz and 1900MHz cellular signal from the cell site is received by the Rooftop Cellular antenna (sold separately). The signal is then amplified and transmitted to your phone through the Device specific phone adapter cable (sold separately). When the phone transmits, the signal is sent to the amplifier through the adapter and then amplified and sent to the cell site through the outside antenna. Compatible with:

All US Cellular/PCS carriers except iDEN carriers such as Nextel, SouthernLinc, Mike (Canada). iDEN users should use the 3 Watt Direct Connection Amplifier for Nextel/iDEN. Not Compatible with 1700MHz AWS (T-Mobile US 3G).

Compatible carriers include: Verizon, AT&T GSM/GPRS/TDMA, Cingular, Alltel, Sprint PCS, T-Mobile (850MHz, 1900MHz), Cellular One, US Cellular, Metro PCS, Virgin Mobile, Cricket, Qwest, Boost Mobile, etc.

Ideal for use with car kits requiring an external antenna. Adapter may be required to connect to your particular car kit.
