How to make a fractal antenna for HDTV / DTV plus more on the cheap

Step 6Create dipoles

Cut 2 more pieces of wire at least 6 inches long and strip them. Bend these wires around the top and bottom screws going longways and contact the center screws. So all three are contacted. Use the wire cutter and trim unneeded wire.

are you sure that the reception you received could be as well be received by the dipole by itself?

The fractals are the dipoles. The line in between is called the phasing harness. It picks up extremely little.

It is possible, depending on the actual impedance of the dipoles which can vary. I had no way of measuring or easily calculating that so the easiest thing was to use a Balun. Depending on your center frequency it may work. Try it both ways.

sir good day,
if i will use a balun for this fractal antenna ,what impedance should i use?ntx.

A 300ohm to 75ohm Matching Transformer/Balun. Hope this helps.

Good day sir, I already made my prototype of this fractal antenna, I follow your suggestion to put a Balun 300/75 ohm matching transformer.Unfortunately I cant test it here due to that our broadcasting here is still analog,Have you tried this in your country? BTW I live here in the Philippines. Tnx. Best regards.

750 ohm ? or 75 ?... Attention that you did wrong here !!! You know what you say?

Jul 19, 2010. 4:14 AMWeegee097 says:

Don't you know the difference between a o and an 0???????? I clearly said 75ohm! Also consider learning English before correcting me. "You know what you say?".

Sorry if I wrote was wrong, but it can not read well. Makes you a space between words. Sorry of English spoken. I use a programme of automatic translation. Only good news.

Um, if you can't even speak a little English without a convert tool, then don't try instructing me on proper grammar.

Professor you never wrong ? ... You get a perfectly man? at the age which is shown ? To no longer asked in vain Ok.? End !

You, sir, are very insulting, and I suggest you stop spamming my posts.
