Range wise: I saw ALOT of those "multi-directional" disk antannas in Wainfleet Ontario while on vacation. I guess the distance from there to Buffalo and Toronto is close enough for those antennas to work & pick up both areas. Not sure how you would go about fixing one though..

The weather is still nice so "experiment". Put the "disk" up for a few days, then put something else up for a few days. That's the only way you know what is best for you in your area. Best of all, you have a tower and the antennas already. What not to do; do not combine them! Good luck and let us know how you do.. . Bill
