2. In-Building Cellular Enhancement System - Wikipedia

   en.wikipedia.org/wiki/In-Building_Cellular...

   A passive system is less expensive to install and is best suited for smaller buildings where one or possibly two MNOs need to be enhanced within the building and are not usually installed in spaces over 100,000 square feet (9,300 m 2). Passive systems require the RF power to be balanced among all the coverage antennas so there is uniform signal ...

3. AN/FLR-9 - Wikipedia

   en.wikipedia.org/wiki/AN/FLR-9

   The antenna array is composed of three concentric rings of antenna elements. Each ring of elements receives RF signals for an assigned portion of the 1.5 to 30-MHz radio spectrum. The outer ring normally covers the 2 to 6-MHz range (band A), but also provides reduced coverage down to 1.5 MHz.

4. Cellular repeater - Wikipedia

   en.wikipedia.org/wiki/Cellular_repeater

   A cellular repeater (also known as cell phone signal booster or cell phone signal amplifier) is a type of bi-directional amplifier used to improve cell phone reception. [citation needed] A cellular repeater system commonly consists of a donor antenna that receives and transmits signal from nearby cell towers, coaxial cables, a signal amplifier, and an indoor rebroadcast antenna.

5. Bars radar - Wikipedia

   en.wikipedia.org/wiki/Bars_radar

   The design of the N011M Bars antenna like the earlier N007 antenna consists of two separate electronically controlled arrays, an X band radar and an L band IFF transponder with a total weight of 100 kg and a diameter of 960 mm. [1] The radar has a peak power output of 4-5 kW [2] and is capable of positioning beams in 400 microseconds, [1] a ...

7. Antenna amplifier - Wikipedia

   en.wikipedia.org/wiki/Antenna_amplifier

   In electronics, an antenna amplifier (also: aerial amplifier or booster) is a device that amplifies an antenna signal, usually into an output with the same impedance as the input impedance. Typically 75 ohm for coaxial cable and 300 ohm for twin-lead cable. An antenna amplifier boosts a radio signal considerably for devices that receive radio ...
