How to avoid the mobile phones Signal Booster vibration
signal
As can be seen from the above description, the distance between the outdoor
antenna and the indoor antenna is too close to the cause of the amplifier
oscillation signal. For the wireless amplifier, it is necessary to ensure that the
distance between the outdoor antenna and the indoor antenna is long enough. It
is best to have wall isolation between the indoor and outdoor antennas. A lot of
engineering problems with amplifiers are caused by the fact that the antennas
are installed too close to each other and the enhancer system is self-excited.
When the host detects the shock signal, it will activate the shock signal
cancellation function. Activating the shock signal cancellation function will lead
to a smaller coverage area of the equipment. If the distance between the indoor
and outdoor antennas is too close, the system isolation is very poor, and the
host cannot eliminate the shock signal. In order to avoid the shock signal
interfering with the base station, the main machine will shut down. So it is very
important to keep enough distance between the indoor and outdoor antennas for
the amplifier system to work. The vertical distance between the indoor and
outdoor antennas is more important than the horizontal distance. The minimum
vertical distance between the two antennas should be more than 25 feet and the
minimum linear distance should be more than 40 feet.
