• Antennas for 160m - The best results work when you have an antenna with a large vertical component. It is difficult to get a horizontal antenna (dipole) high enough to be an effective antenna on 160. However, there are several easy things you can do with your present antenna to initially get on the best amateur radio band

• 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.
