Summary
[edit]DescriptionAnother broken north american television antenna.jpg |
English: Antennas designed to receive the wide array of North American television channels had to span many frequencies and were thus very large. Many of these frequencies have been abandoned, and so have the antennas that receive them.
This example is fairly typical of designs from the 1960s through the 1980s. It actually consists of two separate antennas, a Yagi-Uda at the front (left) that is designed to receive UHF channels 14 through 81, and a log-periodic antenna at the rear (right) designed to receive VHF channels 2 through 13. Both designs are linear, so they can be placed along a single boom. The downside is that the antenna is highly directional, and requires the rotor to point it at the desired source. This example also has some uncommon features, including additional elements in the Yagi section that appear to have loading coils near the boom. The antenna is no longer used, and the wires were clipped off just below the lower edge of the photo. The mast is still in use though, mounting two satellite receivers just above the roofline of the home. |
