Silver Car Mobile Signal Repeater Dual Band GSM Repeater
Why Signal is Weak inside the Car?
There're two reasons for poor signal on your mobile phone while
you're inside your car. The first factor is the distance from the
nearest cell tower. The farther you are from the site, the weaker
the signal you will get. This is true in rural areas where the cell
sites are spaced far apart from each other.
The second reason is an obstruction between your location and the
nearest cell site. Cell phones communicate through radio waves, and
the waves cannot travel through buildings or hills. And even if the
signal is not blocked, it can be reduced or attenuated by glass,
metal, or even trees. This is the reason why getting good signal
can be hard when you're in a basement parking garage.
Introducing the latest in cellular booster technology.
Eliminate dropped calls, extend coverage & increase data speeds
The Vehicle Booster is a very powerful signal amplifier for vehicle
application and is compatible with all mobile phone networks. The
external magnetic mount aerial connects via cable to the booster
unit which is located inside the vehicle. The booster has an
on-board whip aerial which re-transmits a strong and clear signal
within the interior of the vehicle. This booster kit provides
enhanced mobile coverage while traveling in low signal areas.
The repeater improves mobile signals with no negative impact on
1. Specially designed to resolve the problem of weak signal inside
vehicle and yacht.
2. Elegant appearance, Light weight, low consumption, easy
3. Effectively improve communication quality, reduce inside
4. Reduce mobile phone output power, pro-long mobile battery life.
5. uplink high output power, extend communication distance and
enhance performance remarkably at mountain area, forests, high
building area etc.

Question: Will booster increase the RF radiation?
A: No, it will decrease instead.
As it can be searched easily through internet, the tower would
“order” the mobile phone to increase its output power, in order to
ensure successful connection, smooth communication and clear phone
call when the mobile signal bar is few, there will be stronger
mobile output power level when the mobile signal bar is less and
the strongest one can reach 2W; moreover, the mobile phone is
usually as near as less than 5cm to human body when people are in
phone calls. Not only it influences on the human bodies, but also
run out of the battery power much more quickly. Usually the mobile
phone gets hot in such status.
The maximum power level of the booster is 10dBm~30dBm, and it
decreases to be maximum 0.05W when reaching server antenna. And
since the server antenna is installed over the ceiling or onto the
wall, there are usually more than 3 meter away from the human body,
3meter away means at least 40dB propagation loss, or 10000 times
less, 0.000005W, therefore it is too weak to influence human bodies
though it is still a very good signal for mobile phones.
And when a booster is installed, it improves the mobile signals in
the coverage, and the successful phone call can be connected easily
with a much less power level of the mobile phone, thus it will
reduce the RF radiation of the mobile phone tremendously.
