Location: Lower Pacific Heights in San Francisco (ZIP 94115) (TVFool
Mounted on top ridge of peaked roof of 2½ story residential building, coax run 50 ft (triple shielded)
Objective: Major VHF Hi and UHF stations from Sutro Tower (2.3 mi) and Mt San Bruno (7 mi)
HDTV: Vizio M471i-A2
(used to judge reception)Antennas Direct ClearStream 2V
Easy to assemble. High quality construction.
Solidly pulled in all green and yellow stations reported by TVFool, both VHF Hi and UHF.If you need or want the best in this range class, this is the antenna to buy.RCA ANT751
Relatively easy to assemble, except a bolt was missing, purchased replacement from local hardware store.
Also purchased cable zip ties to secure coax to mast and boom.
One element was loose enough to wobble freely due to poor riveting, had to insert shims to stabilize.
Pulled in all green stations reported by TVFool, both VHF Hi and UHF, but not solid on yellow.Good value.Summary
ClearStream 2V definitely more sensitive, clear on yellow UHF channels that break up on ANT751.
ClearStream 2V also picked up a very weak (unwatchable) VHF station not found by ANT751.
Conclusion: ClearStream 2V significantly more sensitive than ANT751, in addition to better construction quality.
However, ANT751 is sufficiently good for my purposes (yellow stations not of interest), and much less expensive ($50 vs $100).
