Found on a forum and it’s pretty cool: uhfhdtvantenna.blogspot.com/

If you don’t want to spend upwards of 70 bucks like I did on a not so great performing Yagi style antenna. Then build this diy hdtv antenna for almost nothing and get better results. My Yagi style antenna I got from ebay was pulling about 60-85 signal strength on most channels and ALWAYS would have continual dropouts making it impossible to watch Free OTA (over the air) digital HDTV. It always dropped out at the most inconvienent time. Another thing I hated about the yagi was it came with a rotor but the rotor had NO INDICATOR! You had no way of telling when the antenna was pointed in the right direction!!! That might work for analog signals you can watch come and go but is just ridiculous for digital signals! Digital signals are choppy, latent and very slow to respond with a moving antenna. Pointing must be very accurate for a strong digital signal. I found it was quite impossible to use a rotor without an indicator when positioning for a certain station. That is why you can see I have an old timey rotor in the setup. I built this bowtie style antenna in about an hour and can’t believe the way it out performs that other antenna. Swear to GOD! I am hitting 88 to 99 signal strength on all my channels now with NO DROPOUTS AT ALL!!!!
