· Horizontal antennas verse vertical antennas-which is best?

· Top loaded and helical antennas for the low frequency bands.

· Five high-efficiency Marconi antennas for the 80 and 160 meters.

· Is TVI worse with a vertical antenna? What can you do about TVI?

· The effects of ground on vertical radiation; how to make an effective "radio ground", and how it improves radiation.

· The extended Ground Plane; phased arrays for outstanding DX signals.

· All about multiband verticals; "sloper" and vertical loop antennas.

· How to equalize your antenna for optimum performance.

· All about " Radio grounds" and electrical grounds-the differences.

· The radial ground screen-is a ground screen better than buried radials?

· L-networks, shunt-fed systems, and the gamma match for verticals.

· Antenna test equipment to adjust your antenna for best performance.
