Transmitter with internal antenna.
Gps antenna metal sheet or not.
Route through a 3 4 inch drilled hole into the building.
Antennas are located around the device with minimal ground clearance ground clearance.
For the best results use the antenna in the centre of a metal roof away from any roof bars or radio antennas.

Low band main antenna implementation.
The gps antenna was integrated into the top metal frame above the watch lower metal frame and utilized the system ground which was encircled by the said lower frame as part of the loop resonant path.
Assemble and mount the gps receiver unit to either the inside of a window not low e glass or to an outside pole or rooftop.
2 4 ghz wifi sheet metal antenna sz0401c.
Ism gps bt stamp metal ethertronics antenna specifications gps single band antenna ethertronics produces a wide variety of standard and custom antennas to meet user needs.
A gps antenna needs to operate with signals from as low as 10 degrees above the horizon 80 degrees from normal incidence and at this angle even a thin sheet of plastic has a significant effect.
If there is no flat metal surface to mount the antenna you can create a ground plane by putting a 12 22cm diameter metal sheet directly below the antenna about 1 2 the signals wavelength which gives 1 4 wavelength per side.
3mm at the bottom and 3 4mm on the sides at the farthest point antenna pattern made with lds and covered with visual painting.
Placement of the gps antenna is crucial to the quality of the data recorded.
Route through a 5 8 inch drilled hole into the building.
Antenna solution for full metal mobile device chassis metal box construction.
Do not mount the antenna close to the edge of the roof as reflections from the ground may interfere with the signals.
Some fancy antennas do not require that you add a ground plane.
0 2mm no vias on transmission lines.
