By itself, this doesn't do anything to boost the signal. It only powers an amplifier.
486829
No. It will not improve the signal by itself. This device only "piggybacks" DC voltage on the coaxial cable to power a remote amplifier.
486830
this is only intended to power remotely amplifiers and other devices. Does not improve signal at all wo amps.
486831
This does not improve signal. One leg is a pass through to provide a remote connection to a 120v AC wall outlet, thus backfeeding the required power back to the amplifier. This is helpful when the amplifier is mounted outside the house where there is no power source.
486832
You can certainly try using it without amplifier, since you live so close to TV stations. I live 45 miles a away from TV antennas. So I used the amplifier.

Between the antenna & the TV; easiest to do right behind the TV. It takes 3 cables: One cable goes to the small power transformer that's provided, that plugs into a 120 outlet. The second cable goes to the TV. The third cable goes to the antenna (or simply connect the 3rd connector to the antenna RF cable). It's not a cure-all, but definitely helps. I get a number of over-the-air HD channels clearly, that previously would not come in at all, or if they did, very poorly. I don't use any "exotic" rf cables, seems as if any will work OK. It has worked perfectly for several years. Between the antenna & the TV; easiest to do right behind the TV.

These are coaxial cables splitters...the thick, round cable from the wall with the copper center wire (usually for satellite or cable tv) can be split to distribute to other tvs in the house. Generally, there is one in and 4 out. It is not necessary to use all 4. All you need to do is loosen the coaxial cable for the source (usually a splitter is located in an attic or basement - where the source comes in and the cables can be routed above ceilings or under floors). Then, buy the additional coaxil cables to split off with. Tighten them to the outs and lead them to the tvs or modems or whatever. BTW - The less you split the signal and the shorter the run, the stronger the signal will be. Sometimes you need to buy an amplifier splitter that boosts the signal if there is a problem with the line - don't do this until yo have a service person check the signal.

The amp has to be close to the antenna no more than 10 ft for maximum performance. From there you can split the signal 4 ways no problem

Unless there is a splitter internal to the unit, RF amplifiers only have one output. The output cannot be split without some signal degradation. Whether degradation is a problem depends on amplifier output signal to noise ratio, gain flatness, antenna gain, cable and connector losses between the antenna and amplifier, RF environment, and a host of other concerns. You basically won't know how much it degrades until you try. To connect more than one device use an RF splitter/combiner, and they only split in half: half the power gets routed to one port and half to the other. (A four way splitter is just three two-way splitters cascaded.) Every split drops the signal + noise power by half (by 3dB), or more, depending on connector and internal losses, which may be another dB or so. Splitting also adds a small amount of noise from various sources including reflection from one port to another. In order to keep additional noise to a mininum, it is best to terminate an unused port with a matched load, which for RG cable would be a 75ohm load. Lastly, minimize cabling, particularly between amp and antenna, avoid cheap cables, connectors, cable bends under 3-4" radius and unnecessary connections. It is a tricky science. BTW, do not buy this cheap, poorly designed amplifier; do some research, spend more and buy from a name brand in RF like RCA or Weingard. Good luck & have fun.

I was going to use a preamp but saw a video for installation. The preamp interfered with the signal. So I am not using a preamp. Watch YouTube brian shaw's, how to install two hdtv antenas. That will give you a better idea.

We had to get a booster box. We mounted the antenna and booster box in our attic. The farther away from the TV's the number of stations were fewer. It solved everything when we got a booster box.

ALL the stations I get are 60 miles or closer, with some less than 30 miles and there is no over-amplification apparent in any of them; from the bottom to the top. I have a long run of cable with 2 connectors and have split to a second TV with NO issues at all. One TV is HD 1080P and the other is not. The clarity on all channels is excellent. It can't improve a poor signal but will give you all that is received.
1883836
Yes - there is no need for any other cable. Just be sure to get the preamp as close to the antenna as possible. Be sure to use a top quality coaxial cable, and keep its length under 100 ft. If you are going to use a splitter, for more than 1 TV, that can be in the house.

I live between to major cities that broadcast. I have it pointed in the direction of the closest city. It picks up well, but I also have an amp on it because of my cable run. I can pick up the other city to the back side of the antenna as well but not as strong. If I turn it to face the other city it does have better gain. The 2 cities signals are basically the same distance apart, within 5 miles. It is sort of multi-directional, but it does have a weaker side of reception if you are between 2 cities. I just pointed it in the direction of the signal and that was it. You really shouldn't have to move it if your broadcast towers are in the same relative area. So, I guess in that respect you could say it is multi-directional.

I just wanted to confirm what Jeffrey said as I have done exactly that. I installed my antenna in my attic and ran a cable down from it to the box outside my home where all the cables come together. I then disconnected the cable coming from the road and connected the antenna cable. Done. I had a strong over-the-air signal being broadcast to all my TVs.If you are planning to keep your internet access through your cable provider, you'll want to do one extra step. Use a signal detector to find out which cable in the box outside is connected to the terminator being used by your cable modem. Then, take your cable provider's line (coming from the road) and connect it straight into that cable. I just wanted to confirm what Jeffrey said as I have done exactly that.

yes, your cable comes from the amp on the antenna into the house and then goes to the power suppy that's plugged in the the wall before any splitters. It's a great amp as long as your not to close to a transmitter, then it might overload your signal
1152273
as for the cable it self. you want to use the shortest run possible (the longer the run the more chance for signal degradation and interference) You can mitigate some of this by using a "quad shielded" cable. Again, try to get the least distance between your set and the antenna. If you run more than one set or you are farter from the TV station than 50 miles. You will need a antenna booster.

Ray: Just go to Home Depot and purchase a 15' length of 1 1/4 " diameter aluminum pole. Any pole will do however. This antenna works best in the attic. Just mount the pole on the crossbeam somewhere and then aim it in the appropriate direction. In my case I bought a $10.00 pre-amp to give the signal a boost but I probably would not need it. It sounds like it will be outside. That's ok. Just a utility pole of some kind will work. I assume you will anchor it with a cement foundation, which is why mounting it inside(in the attic)works better. It is a Great Antenna and delivers HD pictures. You save money too. You won't need Cable or Satellite Dish anymore. Ray: Just go to Home Depot and purchase a 15' length of 1 1/4 " diameter aluminum pole. Any pole will do however. This antenna works best in the attic.

You've probably made a decision by now, but I'll answer anyway. Yes, it will improve signal power levels, but it's unlikely to improve quality with such a high SNR already. I'd leave it be unless your cable company suggests that your return signal needs improvement. You'd likely end up with a +7 dBmV, an SNR of 35-38, and a return level of 38 dBmV.I'd see if your cable company can come troubleshoot the signal first. Amplifiers should only be used for low signal at the point of entry or for a home with many outlets and splitters.

If it turns out that a preamp is needed (due to longer distance to transmitters and therefore lower signal strength), placing the preamp close to the antenna means that you're boosting TV signals rather than boosting noise along with the TV signal. On my setup, I actually have an antenna-mounted preamp AND a distribution amplifier inside the house. But my reception area is quite problematic (and I also split the signal to two TVs), so you might not have to do that. But it's always best to get primary signal amplification as close to the antenna as possible, in order to minimize the amplification of relative noise. (Even good quality cable can have some amount of noise induced into it from stray interference sources, so if you can amplify close to the antenna end of the cable you gain an advantage in signal-to-noise ratio.)

I don't know how else you'd do it. I'd recommend amplifier(s) as well. My splitter is approx. 10' from the antenna and splits to 2 TVs, which are approx. 40 and 50 feet from the splitter. Each TV has an RCA 10dB video signal amplifier 50-900 MHz model VH100 (Walmart, approx. $13) - works great!
