Hereyou ll find simple verticals and dipoles, as well as quad and Yagi Projects and other Antennas thatyou can build and amount of available space should be high on the list of factors to consider when selecting anantenna. Those who live in urban areas often must accept a compromise antenna for the HF bandsbecause a city lot won t accommodate full-size wire dipoles, end-fed systems or high supporting struc-tures.
