Antenna Photo Gallery PurposeThe purpose of the photo gallery
Antenna Design & Construction is a major challenge for most radio amateurs. That is not because they don't know a lot about antennas. It is because of property lines, neighbors, power lines, trees, city ordinances, land-use covenants, spouses who fail to appreciate the beauty of antennas, legal liabilities, limited funds, limited time, and other issues. Radio handbooks and engineering texts have plenty of information about huge rhombics, broadside arrays, end-fire arrays, Beverages, parabolic reflector arrays, towers, and other antennas that would be wonderful if they were not excluded in many cases by one of more of the previously mentioned constraints.
How have others Overcome these Problems?
Everyone doesn't have the same set of problems. Some have acres of land, relatively unlimited funds, plenty of time, and everything else required for a first-class antenna farm. However, most people don't have all that. Most are faced with similar problems to some degree or another. That is one reason the antenna installations of others tend to be so interesting. How did they manage to install a 160-meter antenna on a small city lot, or even a decent 80-meter antenna? What did they use for supports? How did they guy a tall tower, or if they didn't guy it, how did they secure the base? Does it tilt-over, crank-down, or do they climb it? What lightning precautions did they take? How did they get an open-wire feed-line into the shack? Do they rotate the tower or mast, or only the antenna on top, and how? What kind of balun did they use, where did they install it, and how did they support it? What kind of insulators did they use? How did they orient the antenna with respect to power lines? Questions like these are practically endless in the minds of those faced with the practical implementation of antennas.
Antenna photographs can help answer questions like these. They also can stimulate creativity. Someone else's solution may not work for you, but a variation might. Beyond practical construction ideas there can be theoretical understanding rewards. How does that strange antenna work? Can it work? Is it a breakthrough design or a design based on someone's theoretical misunderstandings? If it can work, how can I use what I just learned from realizing how it works?
