For the best results use the antenna in the centre of a metal roof away from any roof bars or radio antennas.
Gps antenna metal sheet or not.
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.
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.
Pin 1 50ω transmission line pin 3 pin 2 r1 r2 r3 r4 through hole through hole antenna outline vias.
Transmitter with internal antenna.
Low band main antenna implementation.
This mount is suggested only if you used a heavy enough gauge sheet metal for the ground plane the thin hardware store variety aluminum will buckle and throw the antenna off its vertical axis.
3mm at the bottom and 3 4mm on the sides at the farthest point antenna pattern made with lds and covered with visual painting.
2 4 ghz wifi sheet metal antenna sz0401c.
0 2mm no vias on transmission lines.
Transmitter with external antenna.
Route through a 5 8 inch drilled hole into the building.
Placement of the gps antenna is crucial to the quality of the data recorded.
Antennas are located around the device with minimal ground clearance ground clearance.
Do not mount the antenna close to the edge of the roof as reflections from the ground may interfere with the signals.
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.
Any metal close to a gps antenna can disturb the signal in an unpredictable way due to interference from reflections of weak gps signals.
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.
Some fancy antennas do not require that you add a ground plane.
The best solution is to have a dome or even hemispherical radome made from the best thin dielectric.
