Antenna theory: The FrSky receiver antenna puzzle (part 1)
Why does the FrSky XSR receiver have 26mm antennas but the X4R (and many others) have longer 32mm antennas? Is it important that these antennas are exactly 1/4 wavelength or not?
Here's a bit of antenna theory and I also take a look at the circuitry in these receivers for more clues.
Stay tuned for the practical tests.
Here is a link to Joshua Bardwell's video on the subject:
