I'd suggest it isnt worth attempting. The frequency change is more than
3:1 from the original TV use.

There are a lot of simple 2.4GHz designs out there that are worth
looking at.

Hi Group,

I looking at convering a TV UHF antenna to 2.4 GHz, the antenna has a
yagi part with elements spaced every 3 inches and the elements are the
same lenght of about 3 inches.
