Just how vital is the placement of the GPS of antennas to their anticipated level of efficiency? Unlike other devices that you can install just about anywhere you please, wireless antennas may not perform to their utmost potential if you are not too cautious as to how and where you install them. This aspect would have a significant influence on how well they’d be able to carry out their expected functions.

The quality of recorded data is directly proportional to the placement of your GPS antenna. Any kind of metal that is in close proximity to it can disrupt the strength of the signal. This often happens unpredictably and this can be associated with the reflection interference of weak GPS signals.

To obtain nothing less than the best results, veer away from mounting your antenna in close range to the roof edge as ground reflections may run the risk of creating/causing signal interference. Avoid the edges of A-pillars, the reflections coming from them may engender signal disruptions to glitches on your device.

Your antenna can be mounted high up as possible but in the presence of any roll bars, keep it above it. The presence of any metal that is in close range or above the antenna is likely to induce disruptions to the signal.

Mount the antenna as high up as you can and should there be any roll bars, see to it that it is above it. Pieces of metal that are close range to and above an antenna will certainly disrupt the GPS signal.

For non-magnetic surfaces:

Fabric tape or any other kind can be used in securing the antenna, just as long that they are not metallic. Placing on top of the antenna non-metallic tapes will not cause any issues at all. But we recommend that you place the adhesive tape just over the top of the antenna and not underneath it. This way you are assured that it is going to have a good with the aluminum surface.

In case that your vehicle does not come with a metal roofing system, you can have your GPS antenna installed on a piece of metal. However, you must see to it, though, that it is flat and around 10 cm in diameter.

Should this be not at all possible for you to do, go find an aluminum or copper foil. You can use them in creating a ground shaped plane to be placed underneath your antenna. For instance, say that you have a fiberglass roof and you have mounted your antenna on top of the roof, you can install an adhesive-backed foil of metal underneath it, on the roof side.

If there is no possible way you can mount your antenna on a ground plane that is large enough, then chances are high that ground reflections will be coming to it from the antenna ground.

If you have your antenna mounted on something sans a large ground plane, like for example carrying your unit by hand, then what you can do instead is place a sheet of metal just underneath the antenna. This can either be copper foil or silver.

Such GPS antennas come in larger sizes and thus may command a higher tag price as opposed to the standard antenna that comes with a VBOX. You can mount them on a high standing pole so that you can have them as high as possible.
