Here are 2 sites I found with information on how to make Television Baluns.
However, depending on your situation though, You might just go to the Deseret Industries and pick a professionally made Balun for 50¢.


Step 1: Find Parts and Start DIYing

The websites I have found so far are below.

<p>Was Googling around for baluns and found your Instructable. You may want to double check the transformer schematic. On the 300 ohm side where the two windings #2 &amp; #3 connect, I think that net should float, not connect back to the 75 ohm ground. As it is shown currently, winding #2 is shorted.</p>
<p>What is the Deseret Industries?</p>
<p>Sorry, Its a Thrift Store that the Church of Jesus Christ of Latter Day Saints owns. I worked there when I wrote this Instructable so it was the first thrift store that came into mind. I've seen them for about the same price at other stores since (EG Idago Youth Ranch, Savers, etc.).</p>
<p>Thank you for the referral links. They have been very helpful in filling in details between electronics theory and specific application.</p>
You're welcome, I figured that someone might need it eventually. Thanks a lot DTV for making our public TV viewing experience a pain in the butt. Until I built my first antenna I was practically doing the little antenna dance to get PBS's small for my siblings. (^_^)
