The multi-directional elements offer the power and efficiency normally found in antennas up to 10 times its size.

Plus, it's Amplified!

The FLEX includes our new ClearStream 20dB USB In-Line Amplifier System that provides added range and maximum signal reception to ensure consistent signal performance for reliable picture quality and reception.

ClearStream FLEX Ultra-Thin Amplified Sure Grip Indoor HDTV Antenna is rated 4.5 out of 5 by 15.
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 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 For indoor antennas this is the best Tried nearly every antenna Target sells, and none worked very well. I have used antennas direct in the past, with great results, and this time was the same. Very easy to install, and get over 40 channels in our area, more than we expected. Very good purchase.

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 3 out of 5 by from I bought 3 One of them helped a lot . There was a window we put it in and it really helped . The other 2 did not help at all . The adobe walls seemed to block them . I would only recommend if you have easy access to line of sight of them broadcast tower and nothing impeding the signal

Rated 5 out of 5 by from ClearStream Flex vs Mohu Leaf 50 Bottom Line.....I wish I could return my Leaf barely worked with or without the I purchased the Flex from Antennas Direct and it works great, never even had to try the amp. I'm connecting to a Tablo device and my TV services cost is no $0.....Thanks guys!

Rated 5 out of 5 by from Improved my reception! It was very easy to set up and install. I noticed the difference at once. Stations that were weak before now come in very clear. The only suggestion I would make is to make available an optional/extra "stand" to sit it on a bookshelf instead of the wall.

Rated 2 out of 5 by from ClearStream Flex Disappointment Very disappointed with antenna after all the good reviews. Antenna would only receive 8 channels in the Orlando area. Had use velcro to make it stay up as the tape provided did not do the job. If you can use an outside antenna, do so.
