Build the Pennyloop UHF Antenna

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 antenna is about 18″ tall and 9″ wide. The Pennyloopantenna 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. The antenna did not need to be excessively tall, but needed some additional height to cover each of the signal layers at the same time. This design goal was achieved in the Pennyloop by having a second loop installed on the original feed point. It served several purposes. It increased the gain substantially, focused more on the horizon where the signals were coming from, and gave the additional height needed to be in each of the signal layers simultaneously.
