• 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.

• Homebrew 5/8 Wave HF Vertical Antennas - The advantage of 5/8 wave antenna is that it has the lowest angle of radiation and has about 1dB more gain when compared to 1/4 and 1/2 verticals. So the 5/8 should be the favourite choice for DX.
