When does a GPS antenna need to be active?
Active GPS antennas have additional power requirements which will be drawn from the receiving device’s batteries. To save power the LNA should only be active when the antenna is in use. These simple antennas do not have an LNA or alternate means of signal amplification and therefore do not require supplementary power.
How long does a GPS cable need to be?
The cable length should be kept short, under 1 meter (3.3 feet), with passive GPS antennas as they require proximity to the receiver and minimal losses from the connecting line to perform optimally. Paired antenna systems are known as reradiating antennas.
Can a 4G antenna be tuned to cover GPS?
The 4G antenna can be tuned to cover GPS and the GPS input should be isolated from the LTE/4G antenna. The antennas are connected via an auxiliary GPS antenna SMA connector to which a suitable 50-ohm antenna cable can be attached. This allows the signal to be looped between the two antennas.
How is a GPS antenna connected to a transceiver?
When appropriately connected to a GPS transceiver, the GPS antenna is able to transmit and receive the specific radio frequency signals needed for a GPS device to perform its time, location, and navigation functions.
