Gps Antennas -The Types Available

A Gps  is only as good as the Gps signals it might probably receive, so why not make sure that you are receiving the very best signals

Gps antennas are useful items of electronic gear however field situations are sometimes tough and might  unfavorably affect them.  Gps antennas are becoming better, and you can certainly get Gps signal indoors, but it   not all the time certain.

Gps antennas are   devices that helps to boost the reception signal to a Gps receiver, whether it’s a standalone receiver or an embedded receiver. Usually a Gps antenna is used in a situation where the Gps receiver itself is somehow faraway from a line of sight to the sky, (as in a car), to help the Gps reciever see the sky without having to be moved. Gps antenna could also be purchased for a spread of budgets .  Cheaper home types can be made with fairly frequent parts.

Gps reception can solely be reliable in case the antenna has a free sight of the sky . Passive Gps antennas do not incorporate a Low Noise Amplifier (LNA). When connected to a Gps , it’s the internal amplifier within the Gps  that  strengthen the weak signal of the passive antenna.

So when should one employ a passive external antenna? In situations  you’ve gotten a clear view of the open sky, however when your Gps receiver  has partly, obstructed view of the sky which means it is put  inside the automobile or hidden somewhere  .

A number of varieties   of internal  Gps Antennas can be found .
Internal Gps antennas:

When Gps antennas are  connected to a Gps, it’s the inner amplifier in the Gps receiver  that amplifies the weak signal of the passive antenna.
Internal Gps antennas  means  they’re constructed into the Gps receiver itself   . External antennas are  an option on various models.  All Gps   come with  an inner built  antenna . The performance of the receiver is straight linked to the antenna size ( the bigger the better) .

One type is the internal Patch antenna , which is a square conductor fixed on top of square piece of metal . The benefit of the Patch antenna is that it reacquire the satellite signal faster if it has been lost  . For finest efficiency with internal patch antenna, hold the Gps units   face up and parallel to the ground.
The second type is  internal Quad helix which is a circular tube wrapped with wire. They’re more sensitive to Gps signals . For best efficiency hold the Gps  so that the antenna is pointing up  .

External Gps antennas:
External means it is not built into or onto the Gps receiver. External Gps antennas are helpful when the Gps  is positioned  in a spot where the view of the sky is blocked like in a car , boat or an airplane.

Reradiating  Gps antennas :
I f the Gps receiver does not have a connecting  jack  for external antenna  you should utilize a reradiating Gps antenna  which include two antennas : One receives the Signal from the satellites and the other one is connected to the first one and is located near the Gps receiver . The effect is like an external antenna connected to the Gps receiver.
