9.3 dBi Yagi TV Antenna 470-800 MHz

I build this Yagi antenna , using material that I have in home. I used boom from stainless steel , with boom length 583 mm. And using copper wire with diameter 1 mm as elements and reflector and driven element. 

For wire length of elements and elements spacing. I used software for Yagi Antenna from K7MEM online Yagi Antenna calculator from Martin E. Meserve. 

Thanks to Martin who has been simplest the process of calculating and designing in Yagi Antenna. Just enter the center frequency of Band frequency we want for antenna to cover, enter boom length  or gain we want to get. Driven element diameter, parasitic element diameter and click the calculate in menu and get the result for Yagi antenna design in another page.

As my design in Yagi antenna, I design for Digital and Analog TV for frequency 470 MHz - 800 MHz Band.

I choose center frequency in 635 MHz.

See the attachment result of my Yagi Antenna design. 

Because my design using Metal Boom Insulated , I used yellow plastic as insulated material and plug in the copper wire to this plastic and tight it with tape plastic.

As seen in picture , I am not yet connect the driven element to balun. The Balun design also calculated with K7MEM calculator in another page.
As seen in design picture, this antenna yagi have gain approximately 9.3 dBi.
My goals on this experiment to make sure that this design works in reality and can received TV signal more good than small antenna I have built later as Indoor antenna. I will publish later. I don't now how much gain this antenna have, but have good reception in several channel and also with no noise in several channel.

I will get back to connect this antenna to balun and connector and will see how the result in this week.
