E9E04:

What is the purpose of the series capacitor in a gamma-type antenna matching network?

  1. To provide DC isolation between the feed line and the antenna
  2. To cancel the inductive reactance of the matching network
  3. To provide a rejection notch that prevents the radiation of harmonics
  4. To transform the antenna impedance to a higher value
