Wanting rejection to fend off P25 simulcast distortion, I thought I would check out what it takes to build a cantenna for 800Mhz, based on online calculators 10" seems to be a sweet spot for a 700-900 Mhz cantenna.
This seems like a good candidate for the "can".

I need to find a way to seal the back. I can't find any specifications on what kind gain out the front and more importantly, what of rejection to expect to the sides and back.
Has anyone tried this with any success?
