Comparison Data between Patch Antenna and Film Antenna
| Patch Antenna | Film Antenna | (Angle of Screen) | |
|---|---|---|---|
| Average Number of | 5.269 | 5.449 | 25° |
| Satellites locked | 3.697 | 3.926 | 30° |
| 3.594 | 3.027 | 35° | |
| 4.194 | 3.926 | 45° |
※ 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
- 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)
- Do not stick on the defogger line.
(If do so, the Average Number of Satellites locked will be reduced by 0.3~0.5) - The Film Antenna can be oriented either Vertically(See: Drawing 2-a) or Horizontally (See: Drawing 2-b).
