In the making of Yagi Uda

First, we do a measurement of antenna which is made by use suitable dimension for radiator, reflector and director. Table shown the measurement that we use as our reference.

Elements	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15
Length (cm)	6.1	6.0	5.4	5.3	5.2	5.2	5.1	5.1	5.0	5.0	5.0	4.9	4.9	4.9	4.8

Then, the paper clips were straight up. Paper clip should be really straight to avoid any errors!

For the antenna backbone, the popsicle stick was measured equally for each sticks to cut off the curve in the end of stick

After measured the sticks, marked the area to be discard. Then cut the unwanted region of the sticks.

Next, the popsicle stick is attached together by using strong glue. As precaution, the area that has been cut is trimmed by sand paper to ensure the tidiness.

The paper clip that already straightened up was measured as the table requirement for this antenna. The clip was cut according to length of the elements.

The distance between elements were measured and marked before attached all the elements on the backbone.

The SMA connector was soldered to the coaxial cable and we also solder the coaxial cable with the feed or radiator of the antenna.
