ClearStream FLEX Ultra-Thin Amplified Sure Grip Indoor HDTV Antenna is rated 4.4 out of 5 by 32.
Rated 4 out of 5 by from Does the job Piece of cake to set up does what it is designed to do, unobtrusive indoor antenna - crystal clear picture on channels it receives - wish the mountains weren't in the way of other channel's broadcast signals - not the antenna's fault - it's local geography - the lookup tool was accurate in it's estimate of channels that would be available. Getting the antenna to stay 'stuck' on the painted wall was problematic - the dry desert climate where I live quickly dries up anything with any type of glued surface. Would have preferred the option for a picture-hanger type hardware.

Rated 5 out of 5 by from Did not disappoint! Antennas Direct has listed sufficient research on a variety of antenna products which captivated me such that I bought a good half dozen. Some for my personal use and others I gave as gifts to family. They have all been solid performers. While I've not noticed a functional difference in this rectangular ClearStream FLEX amplified grip indoor antenna over my previous two round ClearStream amplified grip indoor purchases. This FLEX brings in as many channels in metropolitan Atlanta as I have need, approximately 28 - 30-ish. Thank you Antennas Direct for always standing behind your products. You've proven your policies to be solid for me a couple times over the years and just recently. Good stuff, this.

Rated 5 out of 5 by from Great for Cutting the Cord My application required a little more length in coax than what was included. So, I decided to upgrade the cable, and replaced with RG6 Quad Shield for both pieces. I am using a 20 foot piece from the antenna to the USB adapter, and then a 6 foot cable to the television. This allowed me to mount the antenna in a window which was aligned more towards the transmitters. To further increase my signal, I removed the screen from the window allowing more signal to be collected. With Fall approaching, I did not see this as a concern, as I would not be opening the window. I am in a rural area with the local transmitters ~ 62 miles away. I knew this was a challenge as my home is ground level. After performing a channel scan, I was able to view the UHF stations from this market. However, the VHF stations would not decode. This makes sense, as the gain on this antenna is higher for UHF. Also, I am using this antenna to pick up stations farther away than what is was designed for. For just placing an antenna in the window, I was impressed. This product is working "better" than advertised. I see this item as great investment for individuals who want to view their local television programming and not purchase a big TV tower with outdoor antennas.

Rated 5 out of 5 by from Excellent indoor antenna for VHF/UHF "Leaf" style antennas are usually unsuitable for my location since most stations of interest here broadcast on high VHF. I was pleasantly surprised to find this one supporting both high VHF and UHF, which allows me to have a relatively unobtrusive indoor antenna. I am getting good performance with it in my 16th floor window, despite the fact that most stations are 2-edge path from my location. It is a little pricey but is the best solution I have found so far.

Rated 5 out of 5 by from This Antenna WORKS! I have used several digital antennas in the past, including the "highly rated" Leaf antenna. This hands-down SHAMES all other antennas. Of course, you need to find an area that gets good reception- all digital antennas are like that. Once you do, though, it is reliable as the sun does rise. Works so well that I bought a second, smaller antenna for the spare bedroom from Antennas Direct. Well done!!

Rated 5 out of 5 by from Great Antenna I'm working on cutting the cable right now. This is the first indoor antenna I have used, since the old rabbit ears. I can say it does the job for me, here in Tennessee. I ended up attaching it to the second floor window for the best reception. The channel I could not get is CBS. though their antenna is right by the other channels. I guess CBS wants you to pay for their streaming service.

Rated 4 out of 5 by from Does The Job Cut the cable on bedroom TVs and bought these to get 'local' stations. Stations are 40 miles away, and this antenna brought in about 20 stations from El Paso. However, a couple of the national networks were missing. I assume this is due to the distance and the fact that my condo doesn't have a real unobstructed view of them. Easy to use. Only antennas I've tried.

Rated 1 out of 5 by from Overpriced piece of junk Why is this $60? It's just a small piece of plastic and a cheap amplifier. Total cost of the parts is about $7 or less, yet it sells for around 10 times this. Don't get sucked in to the hype! If you want a decent antenna, spend the money to get an outdoor one mounted on your roof.
