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.

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. (Sold as complete systems.)
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.)
