Creating a Yagi Antenna
Parts Needed
- (2) 2x4x8'
- (~16) metal coat hangars
- Matching transformer (like this one for example)
- (2) small washers
Tools Needed
- miter saw to cut 2×4's to length
- strong wire cutters to cut metal coat hangars
- pliers to straighten wire cutters
- screwdriver and a few wood screws
- stapler and ~30 staples
- coax crimper and wire end
- small piece of sandpaper
Procedure
- Go to https://www.antennaweb.org/Address to map out direction and distance to towers.
- Decide on a target RF channel (for Zeeland I used RF channel 8 for 3.1 CBS because that was the most difficult to pick up).
- Figure out the frequency associated with that RF channel (e.g. http://otadtv.com/frequency/index.html). I used 183.
- Measure available space and verify availability of a coax cable to connect.
-
- Enter your target frequency.
- Change “Diameter of parasitic Elements [mm]” to 3.
- Increase the number of elements until you reach the desired boom length. 11 elements will probably be about a 14' boom length.
