Build the Pennyloop UHF Antenna 3 Steps with PicturesThe Pennyloop UHF antenna offers high performance in a very simple and cost effective design. Blazblue Continuum Shift Full Pc'>Blazblue Continuum Shift Full Pc. 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. 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.

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. As with all antenna designs, there are compromises. Some antennas are omni directional with little gain, and some are very directional with high gain. My antenna design, the Pennyloop, offers fairly high gain and is bi directional without a reflector. It will work equally well, in both directions, which is great if you have antennas on each side of your location. The Pennyloop antenna was designed to be very easy to construct with basic tools and skill levels and the design is for coax feed through an appropriate ground block to the television set. This makes for a very easy and straightforward connection. A few building and performance notes Do not use any more coax than necessary to connect your antenna to the TV. Roughly speaking, you can expect about a. B loss per foot of coax RG 6 at UHF frequencies. In a 5. 0 ft. run of coax this equates to a loss of signal of about 2. B. A loss of 3d. B is half of your signal The prototype of the Pennyloop, pictured, has 5. RG 6 that runs through a 3 GHz ground block to the TV and it is mounted at a height of 1. I do not use an amplifier. Also, all connections, especially those going through splitters, will reduce your signal to the TV. If you have to feed a couple of TVs or have a very long run of coax, it may be necessary to have an amplifierbooster near the antenna. If a connection is necessary between lengths of coax, be sure to use a low loss splice barrel connector. These are available, like the ground block, for 3 GHz. A search on www. tvfool. It will be necessary for you to aim the antenna towards the best, or desired, signals you wish to receive. The broadside or flat side should be pointing to the transmitting antenna and you should be able to look through the hole in the loops towards the transmitting antenna direction. If you have multiple transmitters in one direction, or transmitters on both sides of your location, you can average it or you can point more in the direction of the lower powered stations. The antenna has a null off each edge, much like other loops, dipoles and yagi designs, but has a wide beamwidth front and back without a reflector installed that makes it very nice for most installations. The mast mount described in this Instructable makes it very easy to mount and aim your Pennyloop Antenna. Be aware that OTA Over the air television signals can be influenced by a number of things to include obstacles, terrain, weather, time of day and year, antenna height and aim, quality of build, etc. The 6 gauge bare copper wire is really great to work with. It is large enough to make an efficient element while still being easy to bend into shape by hand and with common pliers. Bending the ends of the wires, for attachment to the feed points, is where it gets tough if you choose the heavier wire. Many different materials and possibilities are available for this build and what I have presented in the plans is what has worked best in the interest of simplicity and ease of construction. Be creative and experiment if you choose to do so. It is great fun to play around with element thickness and lengths, connections, etc. Many other websites have detailed information about mounting, aiming, grounding requirements, NEC requirements, etc. The Pennyloop antenna requires very little hardware and offers great performance. Here is a list of what is needed for the build. The list includes everything to build the Pennyloop as shown in the photos. You may choose to mount it in different ways and all the listed items might not be necessary. It is mounted about 34 of a wavelength from the mast. This distance is not critical and I have mounted horizontally polarized loops very close to my metal mast. Test the antenna in a few temporary setups to see what works best for you. Coax RG6 2.

The Pennyloop antenna is a very simple loop antenna to build and offers very high performance. Only simple hand tools are used for construction and NO SOLDERING is necessary to build the antenna. A hacksaw or wood saw can be used to cut the PVC, a metal file to clean up the ends of the wires, a drill, a knife, regular andor needle nose pliers. Construction of the Pennyloop Antenna Please be safe Use safety glasses and gloves to cut and shape the wire. First step is to measure and cut 2 pieces of 6 gauge bare copper wire to a length of 2. If you are using something other than a hacksaw to cut the wire, leave the wire just a little longer than necessary like an 18 or so. After the pieces of wire are cut, use a file to clean up the ends of the wire. Cutting with pliers will leave some very sharp edges so be very careful with the ends until they are smoothed out. Once the wires are at the correct length, use a pair of needle nose pliers to bend the small loops at each end of the element for attachment to the feed point. It is best to grip the wire with about 38 of wire going into the pliers from the side. You will end up with too large a loop to attach to the feed point, and the overall length of the element will be reduced, if you grab too much wire to start the bend. A close look at the photo will reveal what you are looking for As small a loop as possible on the end of the element to secure it to the feed point stud. With one of the small end loops completed, bend the other side in the same direction and in the same plane. It will make it easier in the next steps. You wont have to twist the wire into shape. From that point you should be able to lay the wire elements on a table with all of the wire touching the table. Not one end loop laying flat and the other loop standing up. Now the big element loops can be bent into shape. They can be formed easily by hand. Just take your time as you go around keeping the smaller attach loops in the same plane as the large loop.
