Fractal TV Antenna VS The Ultimate TV Antenna

This video is where i am comparing 2 tv antennas in identical conditions from 60 miles away from the broadcast stations.Fractal TV Antenna VS The Ultimate TV Antenna here the power pack link    • How To Make A  Power Pack  .How to make a tv antenna.how to make a fractal tv antenna. Then a fractal antenna may be your answer. And you can make one yourself, right at home! Fractal antennas uses a fractal design to maximize the perimeter of the material that can receive and transmit electromagnetic radiation within a given total surface area or volume. Sounds complicated, right.This antenna design grew out of my attempts to build an indoor HDTV antenna using fractal patterns after I had watched a TV show and had read a magazine article on the use of fractal patterns in cell phone antennas, My goal was to design an antenna that not only worked well, but one that was easy to build and could be built from easiliy obtainable materials.

The result is an antenna that is somewhat omnidirectional, and performs well receiving digital TV signals at my home from the low end of the VHF high-band (i.e Channel 7 at 174 MHZ) to the high end of the 600 MHz UHF band. (There are no channels in the 700 MHz band in my area, but Channel 51 at 692 MHz is one of the strongest signals here. diy fractal tv antenna for hd digital tv. The first thing I would like to discuss is a little history, theory, and uses for fractal antennas.

Fractal antennas are a recent discovery. First discovered back in 1988 by Nathan Cohen and later published and patented in 1995. A fractal antenna has a few unique attributes as seen in this definition from Wikipedia:

"A fractal antenna is an antenna that uses a fractal, self-similar design to maximize the length, or increase the perimeter (on inside sections or the outer structure), of material that can receive or transmit electromagnetic signals within a given total surface area or volume."

What exactly does that mean? Well, you need to know what a fractal is. Also from Wikipedia:

"A fractal is generally a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole,a property called self-similarity."

So basically, a fractal is a geometric shape that repeats and appears over and over no matter how far out or how far in you zoom magnificatio
Fractal antennas have been found to be approximately 20% more efficient than normal antennas. Which could be useful. Especially if you want to make your own TV antenna to pick up over the air digital or high definition video, increase your cellular range, wifi range, FM or AM radio reception, and so on. Most cell phones already have built in fractal antennas. If you noticed in the past few years that cell phones no longer have antennas on the outside. That is because they have a internal fractal antenna etched on a circuit board which allows them to get better reception and pick up more frequencies such as bluetooth, cellular, and WIFI all from one antenna at the same time
"A fractal antenna's response differs markedly from traditional antenna designs, in that it is capable of operating with good-to-excellent performance at many different frequencies simultaneously. Normally standard antennas have to be "cut" for the frequency for which they are to be usedand thus the standard antennas only work well at that frequency. This makes the fractal antenna an excellent design for wideband and multiband applications."

The trick is to design your fractal antenna to resonate at what ever center frequency you wish to receive. Which means it will look different and be sized different depending on what you want to receive. A little math can be used to figure this out. (Or a online calculator)

In my example, I am going to make a simple one but you may want to make a more elaborate one. The more elaborate the better. I will use a spool of 18 Gauge solid core wire to make a antenna as an example but you could go as far as to etch your own circuit boards for aesthetic reasons, to make it smaller, or more elaborate with more resolution and resonance.

I am going to use the example of making a TV antenna for digital or high definition reception for over the air broadcasts. It is easier to work with these frequencies and they fall around half a foot to a few feet in length for half wavelengths of the signal. I am also going to base it off a common dipole antenna for simplicity and cheapness of parts for VHF. For UHF you may want to add a director or reflector which will also make it more direction dependent. VHF is direction dependent as well but instead of pointing directly at the TV station like UHF you want VHF rabbit ears (dipole antenna) to be perpendicular to the TV station. But there is a little more design to that. I want to keep this as simple as possible as it is already a very complex subject.
