I am about 20 miles SE of Mt. Wilson and using a RCA ANT751 antenna indoor in my upstair room closet. I get about 115 channels (wished it would tell me how many I currently have!). I did not see anything above 69 as well from previous scans (months ago). No new detected channels since then too. I never hid mine. I just leave them in. Haha. Yeah, too many foreign and infommercial channels!
