Cell phone antenna
Being able to talk on a handheld gadget without wires crossways the
world is really a great achievement in technology. Few people stop and
imagine about this minor miracle. However, when someone stuck somewhere
unable to make a call because of a poor cell signal, the appreciation
for this technology can be tested. Regrettably, cellular service
providers have yet to create the perfect, seamless wireless network
that covers every inch of the world. There are many small and large
pockets where their radio signal is weak or non-existent. For most
people, it is not a big worry.
However many have come to rely more and more on their wireless mobile
phone and being able to make a good connection is a soaring priority.
Some have even eliminated their landline phones in favor of their
wireless service. These users may at times need help getting a better
cellular signal. That is where an external cell phone antenna can help.
What is a cell phone antenna?
Simply, a cell phone antenna is an antenna tuned to electromagnetic
waves and also referred to as radio waves that can be physical attached
through a coax cable, to the cellular phone. Cellular signal waves can
be sent and received from the cell phone to the cellular service
provider's towers using an external antenna. Several wireless service
providers now offer wireless broadband service for high-speed. Many Air
Cards offer a way to connect an external antenna to them thus enabling
to improve the reception and speed of the Air Card broadband
connection.
Connecting antenna to wireless devices:
Many of wireless mobile phones are equipped with RF ports that enable to connect an external antenna to the phone. RF ports may be located on the back, bottom, top or side of the cell phone. Sadly some phones have no port that would enable to attach an external antenna to. DB gain generally refers to power gain. Since antennas do not generate power, dB gain is used to determine an antenna's ability to focus energy in space. 0 dB gain antenna radiates extra energy higher in the vertical plane to reach radio communication sites that are situated in higher places. Therefore they are more useful in mountainous and metropolitan areas with tall buildings.
