USEFUL INFORMATION ON ANTENNAS
NMO Mount:
NMO mounts are used to connect your antenna to your vehicle. Most NMO mounts are installed by drilling a hole in the roof of your vehicle. NMO mounts are typically offered as roof or lip mounts. Both types must be mounted on a metal surface.
Wilson Bi-Directional Amplifier / Repeater
The Wilson Bi-Directional Amplifier / Repeater greatly improves signal strength inside a building. It does this without physical connection to your cell phone allowing you to walk around freely during a call. Its advanced electronics are very sensitive and able to receive small signals which would go undetected by most cellular phones. The signal is received by an outside antenna, amplified, then repeated to an inside antenna where it is picked up by your cell phone.
Wilson Cellular Amplifier
The Wilson Cellular Amplifier / Repeater has a better receiver than what's in your cell phone. Its advanced electronics are very sensitive and able to receive small signals which would go undetected by most cell phones. It also has a better transmitter with double the power of your cell phone. This allows your voice to be heard by distant cell sites, increasing coverage up to 50 miles or more.
A cell phone using our amplifier is safer and will use less battery power because the phone thinks it's much closer to a cell site than it actually is. Phones vary their power output based on their proximity to cell sites. Therefore, your phone transmits less power - resulting in safer use and longer battery life.
Antenna Type/Frequency Range
Cellular service bands in the U.S. are usually 800MHz range (806-894 MHz), 1900MHz range Digital PCS (1850-1990 MHz), Nextel (806-821 MHz Tx and 851-866 MHz Rx) and GSM 1900MHz. Although a phone can work on multiple bands, they only work on one band at a time. You may work near a 1900MHz range tower and live near an 800MHz tower. If you want to make sure your covered wherever you go, consider a dual band antenna. If you're not sure of the type of phone network (800MHz, 1900MHz, GMS Range) you're using or having reception problems in, contact your cellular phone Service Provider or local dealer. They will be able find out for you.
Connecting To Your Phone
First off, you will need a way to connect an antenna to your phone. This can be done using an external antenna adapter to connect an antenna directly to your phone. Also, some hands-free kits have external antenna adapters built into them. If there is no way to connect an external antenna to your phone, you might consider a Wilson Amplifier/Repeater. They boost a wireless signal and do not require a direct connection to your phone. Click here for information on how to connect an external antenna adapter to your phone.
Type of Terrain
Terrain can have a lot to do with selecting the right antenna. For flat, more open areas, look for higher gain antennas in the 3db to 9db range. They have flatter, wider radiation patterns. For more hilly areas or areas with obstructions such as trees or buildings, consider a lower gain antenna in the 0db to 3db range. If you travel within different types of areas, consider a 3db to 5db range antenna. |
