I had bought a Wineguard ultra-flat HD antenna for indoors, but it got 11 11-16 channels at most and they would flick off and on every few minutes (digital artifacts/freeze).
I canned it (Returned to Costco) and then went searching for another replacement for outdoors. I had actually intended to buy the ClearStream 2V, but when I got to BestBuy this was the first thing I saw. I had seen reviews for it, but at 50% more than what I originally wanted to spend, I wasn't looking for it.
Call it lazy, call it.... aesthetics, but once I saw how small it was and how simplistic installation would be... I pulled the trigger and bought it (In fact its just been two hours since I left BestBuy).
BEST ANTENNA I'VE EVER OWNED.
The two websites I went to, to predict how many channels I was capable of receiving for my zip code had me at 91 channels, but I most likely would have to select less than half of them based on direction of the broadcast towers around me (SF Bay Area). This thing is pulling in 107 channels (obviously some are duplicates vs SD and HD)! AMAZING. For a solid hour it hasn't lost any type of signal. Not any, small or tiny. Perfect.
Just accept the price of admission and get on this ride.... its worth it!
P.S. It "might" be because I used to install Satellite Dish service for a living, but I just eyeballed the J-pipe mount (didn't use my level) and stuck the flat side facing what I figured was a tiny bit west of north (the direction The main towers I wanted were in). True to its advertising on the box, it picked up everything in 360 degrees around me.
