[Niagara-on-the-Lake gal]

Hi I live in Niagara-on-the-Lake and up until recently have been having great OTA reception, since early spring . Now I get nothing, my antenna picks up nothing.

I used tvfool to originally set the direction of my 4 bay antenna and was happy with the 15 odd channels that I got. Antenna is on the roof approx 35 ft high.

I've tried Adjusting the antenna even slightly , thinking that perhaps wind or storm somehow interfered. Still nothing.

I installed it myself with a regular left over from my cable company. Is there something I should have done, like wrap electrical tape around it. The connections were tightened very tightly so there's no way that they could have come undone.

any suggestions.?

Thanks in advance.
