Answer (1 of 2): With a multimeter you would use a simple antenna bridge; which has a diode detector to rectify the imbalance of the bridge, the multimeter will show the detected current so you can adjust the bridge for null. If you want to check your GPS antenna's resistance, you need to set the unit measurement of your multimeter to ohms, denoted by the "" symbol. Some cables can be used to So, there can be many reasons why you are getting a blurry picture. There are several alternatives to the NEO-6M GPS receiver module that offer similar functionality, including: The main differences between these alternatives and the NEO-6M are in their performance, features, and cost.
