2 element wire yagi for 80m band

Wire antennas are easy and cheap to built. Many amateur radio operators are using for low bands simple wire antennas that are hanged too low to the ground. Radiation angle is 90 degrees, antenna is radiating most of energy to the skies. This is the main reason why is their perfomance decreased by many dB.

There are two solutions: move antenna higher than actually is hanged or use an other antenna. The first is hard to made. But try to take a think about the second: the ARRL Antenna Handbook says in the chapter about two element yagi antennas: the most powerful antennas. Adding only one element to the dipole we got an advantage of lowering radiation angle, good feedpoint impedance and directional radiation. We have deigned a 2 element wire yagi for 80m band as an answer for this request...

Ham Operators Connect Plantation to World:

PLYMOUTH - The Whitman Amateur Radio Club conducted a two-day special event at Plimoth Plantation the weekend following Thanksgiving. Twenty-two area amateur radio operators (or HAMs) set up six base stations and portable antennas and exchanged contacts with 216 other amateur radio operators in 32 states, 8 foreign countries and 3 Canadian Provinces, according to club President Paul Burbine (N1VTI). The HAM operators spread the word about Plimoth Plantation over the airways, explaining about the living museum and the amazement of visitors who interact with interpreters trained to explain the realities of early Colonial life, in the language of 17th century without acknowledging life beyond the 1620s.

107 in the log. Iâ€™ve no idea what my score was since I used N1MM’s DX Serial Contest template to do the logging and the miscellaneous field for logging random text did a hopeless job of being able to edit long club names efficiently. The last time I entered this contest, my log was called into [...]
