For me, a Yagi with no amp receives a very good signal with no cut outs whatsoever. An amp may help in certain situations where the tuner isn't sensitive enough to the incoming RF I suppose, but it could also amplify stuff you don't want, including noise.
Tried a huge custom Yagi, and it was good for "UHF" stations located in the Antenna farm, but terrible for the others (some no where near the farm). With 23 digital channels here (including subs), the standard Tampa Bay Special is best. Since I am about 40 miles from farm, amp is needed for best results.
True, many amps are junk, but the channel master 7777 is always rated at or near the top, and is less than $50 on ebay. Combined with a Tampa Bay Special (I'm sure other cities have their own version) excellent signal with no dropouts, from 23 digital channels, at a cost of less than $120.
The biggest piece of cheap junk (included with AccessDTV PCI card) tested was the Zenith Silver Sensor that many rave about. Useless this far out, as it picked up about 3 channels, even when mounted outside. It does fit into laptop bag, and I still use it when I am in cities very close to the antenna farm. Otherwise useless.
Other bad antenna's:
Radio Shack High-Definition Amplified Outdoor TV Antenna Model: 15-2185
Terk TV55 Indoor/Outdoor Amplified HDTV Antenna
Those bad antenna's are in comparison to plain jane combo antenna with no amp, that was installed on house 12+ years ago. While they worked somewhat, they were no better than old antenna. Testing done on 4 homes in the area. ( Since they didn't work well here, I tried to sell them to others, but didn't work there either). Channel master antenna with amp always did the trick. Actually in many cases, simply leaving old antenna up and installing 7777 amp was good enough to get great signal strength and quality.
