My husband loves big erections. Don't get me wrong, I'm not speaking here about Viagra, I'm talking about tall towers made of metal, long wires strung high in the sky, and tall antennas protruding from car roofs. He loves anything that broadcasts or receives those elusive radio waves, the bigger the better. That is because he is a ham, also known as an amateur radio enthusiast, and all hams love antennas.
Amateur radio has been around since the early 1900's, shortly after Marconi's first transatlantic wireless transmission in 1901. Initially, radio amateurs communicated using Morse code, as did commercial radiotelegraphy, but voice transmission quickly gained in popularity. In order to broadcast on the ham radio frequencies, hams must obtain an amateur radio license from the FCC, and a unique call sign, their ham “name.” Proficiency in Morse code was required in order to obtain an amateur radio license, but this requirement was finally dropped in 2003, which opened up the field to many more interested radio amateurs, my husband being one of them. As a result, the hobby is becoming popular again. There are local clubs to join, as well as national get-togethers called “hamfests” where there are lectures, demonstrations, equipment swap-meets, and licensing exams.
What do hams do? They communicate by radio. They use everything from a battery-powered hand-held transmitter to a massive collection of specialized radio equipment located in a corner of their home or garage, which they call their “ham shack.” (See picture of my husband's ham shack, above, in his library). They talk to other ham radio operators, and participate in conversations that may be local or span the globe, depending on the radio wavelength, the power of their transmitter, and their antenna. And they erect large antennas, perhaps on an outside tower or the roof of their home.
Like Marconi, hams learn early on that it's relatively easy to send out a radio signal, but the distance it travels depends as much on the size and configuration of the antenna as it does on the signal strength. There is an art to constructing an antenna, and hams spend a great deal of effort on it. That is why hams are fascinated by antennas. They are the quintessential “homo erectus.”
