Boost Your Cell Phone Reception by 80%! Here is what you can do:
Portable Antennas (for use anywhere, vehicle, home etc.): a range of phones can be used in conjunction with a small (approx 3") portable antenna that connects to the phone via a cable.
Handsfree Kit Antennas & Boosters (for vehicles): these items can operate in conjunction with a vehicle handsfree kit. The antenna can either be mounted inside or outside the car window and usually is more powerful than portable antennas.
Fixed Antennas (for home/office, vehicles, boats etc.): the phone connects to a "fixed" antenna via a connecting cable. This antenna can either be internal or external and usually is more powerful than portable antennas.
