I am using a WWVB receiver for a project I am working on. The ferrite antenna that the receiver came with has terrible gain and I want to make one that is several times larger.
I know how to make a loopstick antenna resonant for a frequency I want...
What I am concerned about is if the receiver IC has an input impedance that the antenna needs to match. I would assume the inputs just feed into an opamp or a transistor and it doesn't matter.
I remember in my Antenna class constantly talking about impedance matching but I'm pretty sure that was in regards to matching to a coax feed line.
