Antennas Direct ClearStream Juice Preamplifier System
Adding an preamplifier at the TV antenna increases available signal strength. For city, suburban, and rural locations, the Juice Preamplifier System overcomes weak signals and rejects interference from cellular and wireless data services. Use with a 100 ft. or more of coaxial cable from the antenna to the TV and the use of a splitter.
Antennas Direct PA18 Preamplifier Kit
The PA18 Preamaplifer is designed for rural TV antenna installations to provide consistent signal performance for reliable picture quality and reception. Use for weak signals, a 100 ft. or more of coaxial cable from the antenna to the TV, and the use of a splitter.

Receiving (or not receiving) a particular station is the sum total of:
The quality of your receiver (your TV)
The quality of your cable
The length of your cable
and all devices and connectors between the TV and the antenna.
This amplifier addresses mostly only one problem. It is designed to compensate for the reduction in signal strength that happens as the signal travels through the cable. The longer the cable, the more loss you have. You will also have loss as you go through couplers and splitters.
The JUICE captures the signal at the antenna before any losses occur and boosts it to compensate for the expected losses down the line.
If the signal is no good at the antenna, boosting it will not make it better. It is possible it might make a bit of difference on a marginal signal sent to a poor receiver. If you paid $400 for a no-name big screen TV, chances are that TV's tuner is not the greatest.
It is also possible to have too strong a signal. In experimenting, I found that the JUICE made things worse (on my TV) if the cable length was less than 50 feet and no splitter in line.
If you have more than 100 feet of cable and don't get all the stations you want, you definitely want an amplifier, and this is a good one. If your cable run is less than 50 feet, I would try other things first, like a bigger, better antenna.
The JUICE got me more stations and I'm happy with my purchase, but unless you have a long cable run, you can't count on it helping you get that elusive station. Every installation is different and sometimes you just have to use trial and error to find out what works.
I decided to try and cut the cord. For years I had cable, and then I switched to directv. My directv bill averaged $98 per month and really all I watched were the ESPN’s and the network channels. I decided to cut the cord. I have AT&T Internet so WatchESPN streams on my Roku and AppleTV’s at home perfectly. I thought that if I could get the network channels then I could cancel Directv.
The problem is, I am located about 50 miles from the broadcast tower and 2 of the 4 network channels are broadcast in VHF while the remaining channels are UHF. This would mean that I would need 2 antennas. So I went to antennasdirect.com and began researching.
2 websites that were a huge help were
Both websites have data on the closest television towers at your address. They show the frequencies and the direction in relation to your home. Over the air (OTA) television is directional meaning you antenna must be aimed at the tower broadcasting the channels you plan to pick up. (Especially the further you are from the broadcast tower).
I decided to order 2 antennas. UHF and VHF.
VHF antenna (Clearstream 5 – I highly recommend. It works great): https://www.antennasdirect.com/store/vhf.html
UHF antenna (DB8e – This antenna worked wonderfully as well): https://www.antennasdirect.com/store/DB8e-Ultra-Long-Range-Outdoor-DTV-Antenna.html
The clearstream came with a VHF/UHF antenna combiner. So I used the combiner to combine the two antennas. A combiner is nothing more than a splitter used backwards from what I could gather.
I intended on splitting my signal to 4 different televisions. Everything I read said that when you run long runs of coax cable, the television signal is diminished drastically. So, I purchased a pre-amp and a powered 4-way splitter.

I decided I would install my antennas in the attic. I felt like I would get more life out of the cables, antennas, and splitters if they were out of the elements. I wasn’t sure if the signal strength would be strong enough but I thought I would try it, and if it didn’t work then I could mount onto the roof.
I installed the antennas in the attic and hoped I wouldn’t need the pre-amp or the powered splitter. The first thing I did was hook up a regular 4-way splitter and ran a channel search. All the desired channels came in, but the signal strength was too low and there was a lot of buffering. I decided to hook up the powered 4-way splitter and that increased the signal strength a bunch but still it was in the 65-70% range and that was not what I wanted. I then hooked up the pre-amp and boom! I had a 90% or more signal strength on all channels.
I also made sure to use only RG6 coax cable and cut the cables to be as short as possible.
Here are the RG6 cable tools I purchased.

I also used two mounts in the attic. They worked great. Here is the link: http://www.amazon.com/gp/product/B000WOVD1Y/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
That’s it…that is all you need to get free OTA television. I was able to receive all the channels available in my market. WMAB 2/WMAE 12 (x.1 PBS/MPB, x.2 PBS HD, x.3 Create) WCBI (4.1 CBS, 4.2 MNTV, 4.3 The CW) W07BN-D (IND/TBN) WTVA (9.1 NBC, 9.2 ABC) W25AD (TBN) WLOV (27.1 Fox, 27.2 Me-TV, 27.3 This TV) W34DV/W39CA (UBN) WEPH (49.1 CTN)
The best part of all this, was calling Directv and canceling my service.
It got VERY hot VERY quickly - within minutes. I am concerned that it will overheat and start a fire.
It did not seem to amplify the ONE outgoing cable I had hooked up.
It is being returned.

Besides all that, this works as expected for my setup with 100' of RG6 cable from the Antenna, through a surge arrestor, and finally to the TV.
