Comparison Data between Patch Antenna and Film Antenna
Patch Antenna Film Antenna (Angle of Screen)
Average Number of 5.269 5.449 25?br>
Satellites locked 3.697 3.926 30?br>
3.594 3.027 35?br>
4.194 3.926 45?br>
※ Due to the different condition of Satellite receiving will be depended on the measuring location and time, the above data is not an absolute value, just a comparison between Patch Antenna put on the Rear Tray and Seal Antenna.
Installation Conditions
(1)
Stick the Film Antenna on windshield at least 50mm from the Metallic frame of a car. Stick on any location on Glass is available if the location of stick is approximate 50mm far from Metallic Frame of Car. (Please refer (1)~(6) of Drawing 1) (If Film Antenna sticked on Glass location at around 20mm from Metallic Frame, Average number of satellites locked will be reduced by 0.3~0.5)
(2) Do not stick on the defogger line.
(If do so, the Average Number of Satellites locked will be reduced by 0.3~0.5)
(3) The Film Antenna can be oriented either Vertically(See: Drawing 2-a) or Horizontally (See: Drawing 2-b).
