multi directional coat hanger HD TV antenna.AVI

So, speaker wires can substitute for a copper wire if you don't have any on hand?

@starcar1980 I started using 100 feet clothes line wire that I purchased at Walmart for about $4.00. The basic foam board one I did use speaker wire to connect all the clothes hanger elements. Now I just make everything out of the clothes line wire. I have some more videos about some newer designs.

@Shaunbrough You need a 3-way splitter, 3 cables going into it from the 3 antenna transformers, and one cable out from the splitter into the TV, it's that simple, you can pick one up at a Dollar store for cheap!! Other than that, GOOD JOB Buddy!!

[Shaunbrough]

@hailherrosner I believe that you get a better single without using combiners or splitters and you save from not having to purchase the 2 extra transformers and the 3 cables. Some of my newer videos have 2 large phase lines that span over the entire antenna instead of connecting 3 pairs of them.

[starcar1980]

The camera movement is a little too much & slightly dark, can't see the details how you wired the elements. Overall it's a great job! I'm actually planning to make one similar to this, using Greek Life paddles (an ideal college student design).

I d'ont want to slip and fall on this thing ! it's like a cactus

[Shaunbrough]

@bobbygraine Yeah you have to be careful if your face gets too close to it too, it can poke your eyes out. It would be nice to have something to cover the ends of the whiskers up if it is not on a pole in the air.

Please describe more clearly what you called a "Combiner" Do you mean a three (3) way coax spliter going to a single output?

Thank you.

[Shaunbrough]

@RRAYBE A combiner is like a splitter but you can have multiple sources going into it and one single source going out. Most combiners will also work as splitters but a lot of splitters don't work well as a combiner.

how do you get the dimensions of your design? are you using formulas? can you pls. share it to me...im currently working on my project..and i need the calculations for my defense....you'll be a great help for sharing your knowledge...tnx in advance

[Shaunbrough]

@0923rio The whiskers (elements) are 7 inches long and have a gap of about 3 inches in between them. Check out my video about 2 home made multi directional antennas for more information on the dimensions. I have redesigned the antenna a few times and those 2 are my latest design. Also the smaller design that has 12 elements instead of 24 does pretty well and might work better than the other one during storms I am using the smaller one more than the other one right now.

[0923rio]

@Shaunbrough ok...starting in what frequencies can your antenna catches signals?...tnx

[pwojdyla77]

Do you have schematics you can post for how you linked the elements. If I understand your comments correctly you built a newone with just two cables connecting all of the elements together.

[Shaunbrough]

@pwojdyla77 Check out my video How to wire 3 coat hanger antennas together to make one. Someone asked me how to wire them together and I knew I did it incorrectly on this one so I made a video of how the phase lines should be. I drew the 2 sets of phase lines in different colors. When I built a new antenna I used bare wire and used 1 inch pieces of straws to keep them from crossing. Hopefully sometime soon I will post a video with the new antenna.

This looks like a very interesting design! So, this one works well in all directions. Are there any advantages with overall gain as opposed to a normal, flat db4 design? I'm looking to make the highest power antenna possible and have it also be omnidirectional. 

[Shaunbrough]

@gschnettler It works pretty well I can pick up a lot more stations than a db4 antenna. I use to use 2 antennas connected together that I would adjust all the time and this one works much better. I just wish that I could put this outside up in the air instead of having to use it in my screened in porch. Currently I have created another model where the 3 antennas share 2 phase lines instead of having to connect 3 sets of 2 phase lines.

[JackassCommentaries]

you forgot to mention anything about its performance when you connected it to your TV. so, did it work?? how well?? also, i notice that your design would be good for mostly UHF. but what about VHF transmitting channels??? did you pick those up as well with this design??? as you can see, you left out lots of critical information for us the people watching your video expecting to learn something. if you are kind enough, i am sure many would appreciate a part 2 to this video where you elaborate.

[Shaunbrough]

@JackassCommentaries It works pretty well. Unfortunately I can only use it in my screened in porch because I have a condo but it works better than my antenna array that I had previously. The one that I built for my dad probably works better it is 3 feet tall and has 4 pairs of elements on 3 sides with no elements on the inside. As far as VHS is concerned 2 is the only channel in my area that is VHS and it picks it up great. It has been hit or miss before with my other antennas.
