booster cell phone signal, also known as amplifiers or repeaters, work by capturing weak cellular signal outside your home, office, car, boat, camp, etc., are known him to safety, enhancing and distributing. The most popular products on the market contain four main components: the external antenna, amplifier (booster / repeater), the antenna inside, and wiring to connect everything

l external antenna

The external antenna can be omni-directional (can capture the signal from all directions) or directional (works best if it directly into a cell tower). The advantage of omnidirectional antennas that it is easy to install and collect / transmit signals in a horizontal plane of 360 degrees are. They are ideal for recording and transmission towers for several airlines. You want to climb as high as possible where the signal is strongest. One of the disadvantages of the two omnidirectional antennas: 1) its profits are generally lower than directional antennas. 2) They are more susceptible to other RF interference. TheCellphone-Mate CM100-Sis is a good example for a popular outdoor omnidirectional antenna.

The advantage for the directional antenna (Yagi) is that it generally more signal amplification (power) than omnidirectional antennas. They are also less susceptible to RF interference other. Because they offer more profit, the tower can usually be acceptable far beyond what an omni-directional. The Wilson Yagi 304 411 Wideband is a good example of a popular outdoor directional antenna.

Amplifiers

Almost all amplifiers (or recall), two values it in substance. The first is “volume”. Most amplifiers are classified as single-or dual-band band. Except iDEN (Nextel), refers either single band 850 MHz or 1900 MHz, which means that the amplifier is just one of the two frequency ranges means increased. Dual-band, second to promote the band. There are definitely reasons to buy a band repeater relays are dual-band frequency and compatible with almost all carriers.

The second value is the profit, and appear almost all the signal amplifier in this specification. Without too technical Profit is defined as the ratio of output to input. While the specification of electrical energy, the gain in decibels or dB is measured. DB numbers are derived from a logarithmic function rather simple, but all you need to know is, that every increase of 3 dB doubles the power

0.10 dB = gain of 1013 dB = gain of 2016 dB = dB dB 4019 = 8020 = 10 030 db = 1.00040 = 10.00050 dB gain of amplification = 100.00060 dB = gain of 1,000,000

If you were shopping for a cell phone signal amplifier, while you probably have these numbers hit and did not know exactly what they meant. Well, I hope you have a better understanding

When looking for a special amplifier for your application, please note the following:

20 dB – Cars, boats – 4 ft. .. Antenna separation or a direct connection

40-45 dB – Great car, motor home, large boat – 6ft. to 20 feet. Antenna separation

50 dB – Little House, House, Office – 40ft. to 60 meters. Antenna separation

55 dB – Medium Home, Office – 50ft. to 70 feet. Antenna separation

Please note that this table provides the general rules of thumb and recommended applications and distances can vary by manufacturer vary. Remote antenna is very important and should not be overlooked in the selection or design of your system are. Remote antenna is the straight line distance (in 3 dimensions) of the external antenna, the antenna inside. In practice, these distances are slightly shorter than the distance rule up through ceilings, walls, fireplaces, metal roofs, brick chimneys, etc. to block or inhibit a signal channel Linear. The golden rule antenna distances are to keep to your amplifier to go the vibration. In the audio world, this is analogous to obtaining a microphone too close to a speaker and feedback of production.

Internal Antenna

In the antennas, such as antennas on the outside, in different shapes and sizes to serve different purposes and may be omnidirectional or directional. Many wireless products Extenders (Wi-Ex) have a small omnidirectional antenna mounted the stage itself. While this makes installation easy, the device must be part of your home decor, because it can be installed in a central location and must be visible. Most products in the construction of mobile phone manufacturers such as Mate, Digital Antenna and Wilson Electronics will install internally mounted separately antenna.This difficult sometimes, but with a separate antenna inside more flexibility in choosing a focal point of reporting. The most popular antenna for providing omnidirectional coverage internal antenna is mounted on the ceiling dome, such as mobile phone Mate CM222 Inc.. They even low-profile antenna dome and dome antennas as the same lights that are less bulky and fit well to look into any home decor. can

In directional antennas. Wall panel antennas to provide coverage in general a focused coverage of 90-120 degrees. Although coverage is provided only rough in front of a directional antenna, they usually offer more gain than an antenna dome. That is, the panel antennas are ideal for larger rooms close, but a little bit, or hallways. They are also useful if you are not fully capable to meet the requirements of the antenna separation. If directional indoor antenna is pointed away from the external antenna are you most likely to be able to get away with anything less than the recommended distance antenna.

Wiring

The wiring and connectors are used to connect external antenna to the amplifier and play the antenna inside the amplifier a crucial role in how to run your system. Depending on the product, various kinds of cables and connectors are used. Some Wi-Ex and Wilson Electronics products use standard RG6 or RG59 coax 75 ohms. This is the same coaxial cable for your cable TV or satellite system used. Although this type of cabling is cheaper, there are some drawbacks. For cellular and PCS frequencies, on average, lose RG6 6-10 dB signal 100ft.Depending on the actual length of cable you use, it can sometimes be more signal loss of the external antenna provides a gain. Remember that your amplifier to receive the highest possible signal. For this reason, it is advisable to run with RG6 should not exceed 50 or 60 m. For most other amplifiers in the construction of mobile phone signal LMR-400 50 ohm coax is the norm. In comparison, while LMR-400 is more expensive and heavier, it will lose about 3-6 dB per 100 m for cellular and PCS frequencies, respectively. On this basis, LMR-400 RG6 be used before there was a decrease in system performance. For all systems in three parts (external antenna, an amplifier, indoor antenna), it is recommended that the amplifier is as close to the external antenna installed as possible, use the cable as short as possible. For example, if the external antenna is installed on the roof, it is recommended that the amplifier is installed in the attic as opposed to the basement. The shortest length of cable between the antenna and the amplifier, the better. Remember that there is no requirement of separation between the antennas and amplifiers, only between the antennas.
