StudentSA Member Jul 18, 2012 #1 Good Day, I have a Narrow Band FM Receiver that I am experimenting with. I wanted to find out why it has two equal lengths of wire as the antenna? When inspecting the PCB one wire in connected to a point marked "ANT" and the other to "GND". Why would we need to take the ground point as part of our antenna? If reception is weak would it be possible for me to replace this with another antenna that would boost signal? Thanks

StudentSA Member Jul 18, 2012 #3 Thought as much. In terms of orientation would it be better to run them outward from each other in a vertical or horizontal direction?
