Of all the columns I've written, the ones describing do-it-yourself antennas always bring the most response, sometimes years after the original column was written. You shouldn't have to worry about infringing on someone's patent building this antenna. According to the Web site describing the antenna, www. Hoverman originally secured a patent in and
The Pennyloop UHF antenna offers high performance in a very simple and cost effective design. It is also a very compact design lending itself well to a variety of mounting options and locations inside and outside. Outside will give the best performance. The Pennyloop antenna started out as a single loop antenna and could be used with a reflector. It was found through extensive testing, at least in my area, that the UHF signal strength is very "layered". A single loop antenna, or even a simple thick element dipole for that matter, would pick up all of my distant stations - Just not at the same height! A new design emerged from this common issue with UHF signals.
Amateur Radio Stack Exchange is a question and answer site for amateur radio enthusiasts. It only takes a minute to sign up. What would be the difference between a two-bay antenna designed like this:. Assuming that everything about these two antennas are identical aside from the number of bays, what exactly does "adding more bays" do for a bowtie antenna?
To ensure that the best performance is obtained, it is necessary to align or point the antenna in the right direction. This antenna alignment or orientation is an key part of any antenna installation. Incorrectly aligned and pointing in the wrong direction, the antenna will perform poorly. Whether a professional installer, caravaner, or DIY enthusiast installing a television antenna, it is necessary to be able to accurately align or point the TV antenna to provide the best reception. Antennas, particularly those used for television reception have a directional pattern and when they are installed they need to be orientated or pointed towards the television transmitter if the best reception is to be obtained.
