- The Gamma Match
- The gamma match was originally invented as a means of feeding vertical monopole antennas for medium wave broadcasts, which were earthed at the base for lightning protection- Hams are more likely to use a gamma match to feed a dipole or loop element, but the basic theory is easier to understand for the case of a quarter wave monopole.
