Ham Radio Antennas

An antenna is designed to transmit or receive air waves.  It converts electromagnetic waves into electrical currents or the other way around.  Most people think of antennas as working in air, such as for radios, televisions, and automobiles, but they can be adapted for use under water or under ground.

There are many factors that affect an antenna’s performance.  Concerning ham radio antennas, efficiency and bandwidth are important to consider when determining what you need.  Most antennas are designed to operate at a particular frequency.

Who knows what the future holds for antennas?  Rooftop antennas are gone.  In February 2009, televisions with inside antennas will be non-functioning, and vehicle antennas have evolved from protruding outside of the vehicle to running along the windshield.

Nevertheless, a wide assortment of ham radio antennas is available on eBay.  New, used, vintage, and magnetic models for half wave to dual band radios are offered at affordable prices.  Check out the vintage antenna books on eBay as well.
