I am thinking of giving it a go and building this Yagi:
http://www.mncarg.org/projects/uhf6el.jpg
It is designed for 430-440MHz.
Question: If I am using this just for Scanning is it critial that I tune it for the freq I am shooting for?
To answer my own question.. I currently use a Larsen 2/70 antenna that works fine so I would assume this Yagi would pull in 450-460 just fine even though it is cut for 430-440. I just wonder if I would notice the difference.
Question: Anybody know how I would scale this for 450-460? If I shorten the Driven Elelment do I need to shorten the Directors and Reflector? What about the spacing?
Thanks!
