GPS/GLONASS ACTIVE MAGNETIC MOUNT ANTENNA High performance operates at GPS L1 and GLONASS L1 frequenciesFlexible installation can be mounted using internal magnets or screw mount holesHigh gain, low noiseLNA 30 dB 40 dB gain typical; low noise figure 1.5 dB 2.0 dB FAQ Q:The picture is real product?A:Yes,all product pictures are real product.Q:If stock quantity is not enough from link, how to do?A: Contact/Leave message to us, we will reply and help check exact stock within 12 hours. If go to bulk ordering, usually lead time 10-15 days.Q:when I go to bulk several items, and find shipping cost is different, how do I do?A: Shipping cost depends on unit weight, but if you find shipping cost very high,Contact/Leave message to us, we will check whether shipping cost can be reduced.Q:How can I get commercial invoice for company finance?A: Contact/Leave message to us,leave billing address, we will send PDF version there.Q:Is the antenna has different length cable or connectors?A:Yes, can be custom-made, Contact/Leave message to us, we can quote for you.GPS is for SMA Male/Fakra C(blue), which are normal.Fakra C has straight and right angle(90 degree).Wellcome to tell us of your requirements.Q:Is GLONASS better than GPS?A:The 2 systems also differ somewhat on accuracy. GLONASS position accuracy is 5-10m while GPS is 3.5-7.8m.Therefore, GPS outweighs GLONASS in accuracy as lower error numbers are better.Q:Should you use GPS with GLONASS?A:Actually only gps should do its job in case satellite reception is perfect.The combination with another system will improve accuracy when the signal gets weaker.Q:Does GPS work without an antenna?A:GPS (Global Positioning System) systems work by receiving signals from satellites.That isn't possible without an antennaQ:Where to put a GPS antenna?A:In most cases, you can mount the GPS antenna near the top of the underside of your dash (behind or above the receiver).
