I currently have a 3ft parabolic broadband UHF antenna at 60 ft with a Blonder Tongue UHF preamp pointed at the CN tower and receive CBC 5.1, CBC French 25.1, analog Global 41 and CICA 19. I’ve had intermittent reception on , OMNI.2 44.1 off this setup.
No luck with CTV 40.1, 53.1 Citytv, 64.1 OMNI.1, 65.1 Global.
I’d also like to pick up CHCH 18.1, Crossroads 35.1. but have not pointed anything but a small UHF antenna at Hamilton yet with no results.
As I said above my antenna location is 60 ft high (I could get to 70 ft with a mast) in Amherst, NY. It is above the tree line and I can see the towers on Grand Island from where the antenna is. Any suggestions on improving reception on OMNI.2 and picking up the ones I’ve had no luck with yet? Also, would it be worth while getting another expensive UHF antenna for the Hamilton stations or just wait till they move like CHCH to 11.1?

Thanks
