Glass Mount Cell Phone Antenna:

Even though the antennas on this page are rated with their "gain" listed, this type of antenna mounting configuration is the least efficient of all. This type of antenna mounting does not have the benefit of ground plane and transfers the signal by an electrical phenomenon that is called capacitive coupling. There is signal loss between the antenna and the coupling box on the inside of the glass hence this type of antenna configuration will have inferior performance when compared to the same antenna with same antenna cable that is connected directly to the co-ax cable.

example:marine antennas or magnetic antennas or through roof antennas

Smoothtalker on glass antennas include SEMRC205 quad shield low loss co-ax antenna cable. This cable is a flexible cable with a solid center conductor, four layers of shielding and has the lowest loss specifications for cable of its diameter (.205 inches). SEMRC205 quad shield low loss co-ax antenna cable at 15 ft. of length with a connector on each end has less than 1.8 dB total loss at 850 Mhz, and less than 3.25 dB total loss at 1920 Mhz.

NOTES:

1-information listed below shows antenna performance as measured in our laboratory and field antenna performance in the environment listed. Field performance measurements vary with physical location and sometimes show increased performance figures and sometimes show decreased performance figures than those listed below.

2-All Smoothtalker external antennas are available with either FME female or MCT Female connectors. If a SmoothTalker antenna is to be connected to a device or cable with any other type of RF connector, then an antenna cable connector adapter will be required.
