Can I use this all by itself, no amplifier anywhere, between my attic antenna and 3 way splitter to improve signal to 3 tvs? It's a left-over from a previous cable tv installation. All my stations are within 10 miles but have a 70 degree spread using a...

this is only intended to power remotely amplifiers and other devices. Does not improve signal at all wo amps.

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.

Yes, you can do that, but there will be some loss through the 2 way splitter. I run everything through this device. I have 3 cable tv dvrs, a cable modem and a telephony modem all hooked up to this device. Normally it is suggested to run a splitter, 1 leg to your cable modem and 1 to the amp. You do not need to do this with this device

If your connections are good, you are probably on the edge of the reception area. Mounting the antenna higher and outside (if in the attic) will help. Go to antennaweb.org to see if the station you are trying to get is in range. If you are using a splitter for more than one TV, a multi-port distribution amplifier will also help. This is a good antenna for people that live in an area where the TV stations are in different directions i.e. 45 degrees are more. If all your stations are within 20 degrees a directional antenna will do better for distance stations. Hope this is useful.

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.

You'll need an Amp as well. The best one I've tested so far I bought at Radio Shack. It has two adjustable amps; one for the line going to the TV's and one adjusts the gain of the antenna mounted unit. Speaking of which, the amp has a unit that will mount at the antenna and another that will mount inside and need power. The indoor portion will provide power through the coax to the antenna mounted unit, so you'll need to make sure any splitters you have in line have a DC bypass. My house in pretty much in the same situation as yours and this antenna wasn't ideal. While all the panels are facing the same direction, the antenna is strong, just like the much cheaper DB8. However, if you try to point the panels in two different directions (like it's supposedly designed to do), you lose too much gain. Once trying that, I lost more than half the channels I was getting.

It's hard to tell not knowing how or where you are setting your antenna up at. I put my antenna in the attic, just needed to splice into the existing antenna cable in the attic, I purchased RF connectors at Walmart, I also added an additional RF output above my fireplace, so I needed an RF HD split-er and some RF HD Cable. Depending on if you have some distance between your antenna and your junction box (place where all your tv cables meet-up, you can add an RF amplifier. Good Luck

Yes you could but you would more than likely be better off installing an in line amplifier closet to the TV. This unit boost the signal from the antenna not the antennas gain ( ability to acquire signal). I would also suggest that you point your antenna to obtain max signal by going online and determining the best direction for your area.

You need the amp as close to the antenna as possible. In my case it is just a 3' cable from the antenna with the amp mounted on the mast holding the antenna to the roof. You are losing signal strength with every foot of cable from the antenna to the amp so you want it to be as short as possible. The power supply on the other hand can go anywhere. Typically it is near the TV or the distribution point for the rest of the TVs in the house. The power supply can be in the attic if you have 120VAC outlet to plug it in there or it can be in you basement or living room.

You shouldn't need to have another booster after the distribution amplifier in my opinion. I'm driving two TVs and an FM radio just fine with the HDA-200 attached to two UHF directional antennas up attached to my chimney. You may want to examine your input (antennas) to the HDA-200, rather than trying to further boost a signal...

What you want to do is keep the signal as strong as possible till it gets to your TV so an amp close to the antenna (like this product) is a good way to do it. If you splitting the signal or it's a long distance to the TV another booster might be needed to get all the channels you'd want to put that booster before the splitter. If that's not working you probably need a bigger antenna or a taller antenna or you may just need to point it better. If you want to get scientific about it you can calculate the drop in signal stretch for the length of cable and the number of splitters you have and then buy the boosters or amps that will compensate for that drop.

Yeah, if you are hooking up multiple TVs or have long cable runs from the antenna an amplifier is the solution. Note: Amplifiers are NOT the solution for weak signals due to distance from the stations. Your best bet there is to buy a bigger/better antenna. The amp can only work with what it gets from the antenna. If all you're getting is static than amplified static is what you'll get with an amp added.

Try it. It might work. I have my outdoor antenna on the roof of the house, and have this amplifier near my HDTV in the basement. It has worked so far.

Reading the description of that antenna, I noticed that it has a built in amplifier. Try using it first, to see what your reception is, before adding a separate amp.

Splitters are never a good thing, lose too much strength, and you're probably not going to watch TV in both locations at once. I use an A/B switch...A for garage, B to send to my computer in the house, the amplifier/booster (whatever it is) goes between the antenna and A/B switch. I have several cable boxes in the house, but free digital TV to use when working in the garage or messing with computer...

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.

You will need a pole to mount it on and cable to connect it to your TV. The pole I got is this http://www.amazon.com/gp/product/B000WOVD1Y/ref=oh_details_o04_s00_i01 I would try it without an amplifier. Unless your signal is really weak you shouldn't need one.
