Charles KC8VWM and how he made my optimized VHF Yagi Antenna:

ON6MU 9el Yagi Antenna Design

The computer optimized 9 el. homebrew antenna is performing very well. I have
made many long distance contacts using the ON6MU VHF Yagi antenna. I have the antenna
located only 35 feet above the ground. (See antenna photo titled KC8VWM to
see how high it is mounted on my house.)

The very first day I put up the ON6MU antenna, I contacted two stations in
Toronto Canada which is located 507 km. away from me. Other stations I
contacted were located in other states like Buffalo, New York, Pennsylvania,
Indiana,  Tennessee, Michigan, and West Virginia.

I was also picking up weak EME signals later that evening on 144.127 MHz.
using mode JT65B.

 construction of the ON6MU antenna design can be found here:
