I guess I could say you go flip burgers at McDonalds for 4 hours & take the $20 to Radio Shack & buy their basic yagi. While I admire your interest in building an antenna, you'll spend more money building something that probably won't work as well as what Radio Shack offers. Or...find someone with a VHF TV antenna who now has cable & offer to take it down if you can have it. That will cost zero & will likely still outperform anything you'd likley build up yourself. I'm not trying to be a wise guy, but with how cheap yagis are, it makes no sense to attempt to build one. If you have nearly $100 to spend, I suggest you Google the APS-9 antenna. It's a 9 element yagi that will far outperform any TV antenna of the Radio Shack yagi. And it's on sale now at Stark Electronics...If you have $200 to spend, the best yagi available is the APS-13...But if all you want is 100KW stations at 80 miles, the APS-9 will amaze you & the Radio Shack yagi will probably suffice. Let me know what you settle on & how pleased you are...
