3G Repeater (zesilovač) Signal 3G-500
The included accessories
Signal 3G-505 A67105 amplifies 3G signals inside buildings. The device is ideal for locations where the range of a cellular network allows for use of UMTS/3G terminals (for high-speed data transmission - video calls, mobile Internet services etc.) out of buildings, but is insufficient for indoor operation. Such locations include some remote places (long distances to base stations), but more often rooms in old buildings with thick walls or in basements and cellars (e.g. pubs, coffee shops). Another barrier can be modern windows with panes covered with metallic layers.
Distinguishing features:
  • Support for 3G phones and modems operating in 1920-1980 MHz, 2110-2170 MHz bands
  • AGC (ALC) - automatic gain/level control
  • MGC - manual gain control (attenuator)
  • Gain suitable for the coverage area
  • Indoor coverage area up to 500 m2
  • Easy installation (Plug and Play)
  • The packaging does not contain antennas (they should be selected depending on local conditions - outdoor: A741030 or A741020; indoor: A741001 or A741002)
  • 24-month warranty
Contents of the set:
  • 3G repeater,
  • Mounting elements,
  • Power supply (230 VAC / 9 VDC 3 A),
  • User manual.
This product can solve 3G signal problems in hotels, boardinghouses, and various buildings, ensuring smooth communication and Internet access.
Large systems (with several indoor antennas) require to use splitters ( A6812 or A6813 ).
Important features:
ALC. Automatic gain/level control with dynamic range of 20 dBm, optimizing operation of the device to the actual conditions.
MGC. Manual gain control (input signal attenuator) allows manual setting of signal strength (independently in downlink and uplink directions) to keep signal levels within desired limits.
Installation of the Signal 3G-505 A67105 repeater:
  • find a place outside building with a good 3G signal ,
  • mount the outdoor antenna ( A741030 ) so that it is directed toward 3G base station,
  • choose a location for installing the repeater somewhere inside the building to place the indoor antenna in the central part of the building/hall/room to be covered,
  • check if the distance to the place outside is not longer than 10 m,
  • install the Signal 3G-505 repeater in the suitable place in the hall/room (away from heaters etc., ensuring natural ventilation),
  • be sure that the two different antennas are connected to the dedicated marked sockets,
  • connect the AC power plug to a wall outlet (230 VAC).
The repeater Signal 3G-505 A67105 connects with outdoor and indoor antennas with coaxial cables, which provides flexibility in selecting the place of its installation, taking into consideration the connection to an AC power outlet.
Below there is an example of using the repeater for better 3G coverage in a house.
