I have searched the web unsuccessfully for a simple antenna design for receiving low vhf HDTV signals (channel 3, 55 miles away). With information from ham radio sites and from (google cheap and easy tv antenna because I am not allowed to post url's), I decided on the following design based on a simple folded dipole.
3/4" or 1" tape measure
3/4" pvc tee
1 1/4" hose clamp - 2 ea.
foam thread spools - 2 ea.
wire - 20"
electrical tape - 12"
reusable zip ties - 2 ea.
I used these items because I had them on hand. The tape measure I used was broken but inexpensive ones can be purchased for $2.00 from harbor freight. The spools and zip ties are not required if you are going to fold your antenna or leave it extended. I prefer being able to roll it up.
1. Cut two pieces of the metal tape measure to length according to a cheap and easy tv antenna website. Cut the entire length first and then cut it in half because the tape measure may recoil.
2. Tape the spools to one end of each piece of the tape measure.
3. Scrape 3/4" of the paint off the other end of each piece.
4. Cut the wire in half and strip the ends.
5. Clamp everything together as seen in the pictures. Make sure the wires are contacting the scraped area of the tape measure.
6. Connect the free ends of the wires to the pick up point of your antenna. Mine can be seen attached to my coat hanger antenna.
It actually works for me. I am able to maintain a 75% signal strength for channel 3 at a distance of 55 miles.
