Choose the product that fits your application.
Determine your application by deciding if your
primary need is voice communication (cell phone) or
data communication (computer). If your primary need
is data communication, a direct connect (inline) amplifier
will provide the best, most reliable connection
possible.
The Digital Antenna brand cellular amplifier and
repeater products below are dual-band 800/850 and
1900MHz and support all US cellular and PCS carriers
and technologies. They are not compatible with iDEN
(Nextel, SouthernLINC, Mike.) iDEN users should see
the links on the bottom of the page.

FAQ
Do you have an existing cellular signal to boost?
Existing cellular signal of -70 to -90dB (easily complete calls with few
dropped calls) at the location of the outside antenna is required to use a
repeater. If the cell signal outside is below -90dB and as low as -110dB
(difficult to complete calls) a direct connect cell phone amplifier should
be used. An amplifier or repeater cannot amplify a cell signal that is not
present. A direct connect amplifier is recommended for use in areas where
there is extremely low outside cellular signal or to enhance data and
Internet connections. In addition, optional directional and higher gain
antennas will give increased performance to your amplifier or repeater in
low signal areas.
Should I use a direct connect amplifier or repeater? What is the difference?
Both amplifiers and repeaters boost cell phone signals up to 3 watts and
will deliver similar benefits. A direct connect amplifier will provide a
range of up to 50+ miles from a cell tower and supports a single
phone/device. A wireless repeater offers a range of up to 30 miles from a
cell tower and can support multiple phones/devices simultaneously.
How does a direct connect cell phone amplifier work?
Your cell phone is physically connected directly to the amplifier by an
adapter cable. The amplifier then connects to an outside cell antenna. (Cell
phone antennas and adapter cables are sold separately.)
How does a wireless cell phone repeater work?
An advantage of a wireless cell phone repeater is that no physical
connection is required to your cell phone, however, a stronger outside cell
signal (-70 to -90dB) is required and specific installation guidelines for
outside and inside antenna must be followed. The outside antenna receives
the signal from the cell tower, the signal is amplified by the cell phone
repeater unit and repeater to your cell phone through the inside antenna.
This technology also allows the user of multiple cell phones simultaneously.

Options:
Recommendations
are based upon achieving proper antenna separation when using cellular
amplifier/repeater and outside signal strength of -70 to -90dB.
Separation Requirements:
Wireless
amplifier/repeaters (all cell carriers except Nextel/iDEN):
-
DA4KMR-10A (40dB Gain): Requires 2' separation and metal automobile roof
-
4KPR-15R (40dB Gain): Requires
10' separation
-
DA4KMR-30U (40dB Gain): Requires 20' and roof/wall structure
-
DA4KSBR-50U (60dB Gain): Requires 40' and roof/wall structure
-
4KMR-30M (50dB,
RV/Marine): Requires 12' and roof/wall structure
-
4KSBR-50M (70dB,
RV/Marine): Requires 25' and roof/wall structure
All
amplifier/repeaters require the outside antenna to be installed outside
of the structure (house, car, office, building, boat) and the inside
antenna be installed inside of the structure. Wireless
amplifier/repeaters can not be used with both antennas in open air (i.e.
convertible car or open air.)

Recommendations by vehicle type:
The above dual-band cell amplifiers and repeaters are for cellular and PCS
carriers only (Cingular Wireless, Verizon Wireless, T-Mobile, Sprint PCS, Qwest
Wireless, Virgin Mobile, Midwest Wireless, Cricket, US Cellular, Alltel,
Cellular One, Western Wireless, etc). Not compatible with iDEN: Nextel,
SouthernLINC, Mike.
