Here is the completed antenna, showing phasing lines, elements, impedance
transformer and coaxial feedline to the DTV converter.
For an enlarged view, click on the images.
Simple wood screws and washers hold the phasing lines in place. A piece of insulation (blue) is used to keep the phasing lines from shorting where they cross one another.
An impedance transformer - available at RadioShack and Walmart - matches the antenna's 300-ohms to the coaxial line's 75 ohms.
Here's what the impedance transformer packaging looks like at Walmart.
