answer 6
I connected three tvs. I had bought 3 flat antennas for three tvs and was ok with result but not thrilled. I bought the rocketfish and connected 3 tvs to just one antenna and returned the other 2 and my reception is great and I saved over $100 returning the other antennas. I can't see why 4 would be any worse. I had to move the antenna several times and put it in the basement by a window on the south wall to get great results. Good luck. My tvs are all flat screens. one 55 inch one 50 inch and one 32 inch

More than likely yes. It will depend on how strong the signal is. As long as you have a strong enough signal, you can split it between 4 TV's with this.

answer 4
Assuming that the signal output from the antenna is sufficient to work well with each of the TV sets taken individually, the answer is "yes." 3 db gain is only twice the power, so if the signal from the antenna is insufficient to run any of the TVs, at least marginally, then an additional RF amplifier giving 10 db (or maybe more) gain will probably need to be added between the antenna and the splitter.

Antenna wire will connect to the single INPUT port. The four output ports are for four tv. If you have one tv, connect your wire from port #1 your tv.
Some say cap the unused ports with 75 ohm termination resistors.

answer 2
I am using this with an antenna mounted in the attic. I was getting some weak signal depending on time of day, weather, etc. The coax run is about 60 feet. Adding this amplifier improved the signal. But read on...
I did a little experimenting when I first hooked it up (about 2 months ago). At first I installed the amplifier close to the tv end of the coax. It did not make the reception better. Then I installed it in the coax line close to the antenna. THAT made the signal stronger. And in doing a little more research with a friend, he tells me that what he has read is that you need the amplifier as close to the antenna as possible, especially if there is a long length of coax between the antenna and the tv. My situation proved that to be true. But they don't really mention that in the instructions. The problem in my case was to get a/c power to an outlet in the attic. To test it, for several weeks I had an extension cord run up through the attic hatch. I have since run a permanent romex wire and receptacle. I must say that this amplifier DID improve my signal. I would recommend.

It will work by amplifiying the signal from your ISP to you by ~3dB but your uplink signal (You to the ISP) will suffer by -7dB. Will not help out overall.

It is DC current power. Some components have this feature. Then you would not need to use the included AC adapter. Most components connected to this amplifier do not have DC current flowing thru the coaxial cable connection. The AC plug in is needed then.

If you didn't want to use the #1 output, you could just wire it to +12V, positive center to that jack. If you still wanted to use all of the jacks, you'd need a power inserter like a Sonora HRFPI or a Holland HR PI-BW.

If you are really close to the broadcast towers an amplifier will degrade your reception. If you are close, try your indoor antenna without the amp. If your reception doesn't get any better you need a stronger antenna. Either indoor or outdoor.

No. This is intended to amplify an already good signal at the entry point in your residence or business so it will reach a distant receiver or TV over a long cable run. It will not fix an already bad signal, just make it worse since it will be amplifying a bad signal.

Not sure how far away you are from the trasmitting tower(s).
Try a long distant , omni directional outside antenna from Best Buy.
They have a 15 day return policy. If you notice no difference
Return the antenna. I picked up an antenna and 100 feet of wire.
Put the antenna temporary on my roof and ran the wire in the front door
To the tv, just a test. Give it a try.

Hard to tell without being there, but if you're getting bad reception with an amplified HD indoor antenna, an outdoor one may be your best bet. (I'm assuming you've tried moving and turning the indoor antenna to find the best arrangement.)

There are very good "plain " splitters that would work quite well in the situation you are trying to use. I would not use a powered amplifier like this nice RF-G1179 for that job.

No, it is not bi-directional in that sense. The reverse direction only passes the lower frequencies. You need to use an un-amplified combiner that uses an architecture that allows multiple incoming signals to be mixed into a single signal.

answer 3
I do not believe this adapter will work for your application. The bi-directional function is referring to being able to pass digital information back to the source as needed for digital cable TV applications. Cable wiring from a cable company passes all kinds of digital information both ways because it also includes Ethernet information.
To use two or more signal sources for one TV (or other display appliance), you would need either a video A-B or A-B-C selector switch or a component stereo system (that would decode surround sound for a home theater system) with selectable inputs.

Question

No signal once powered up...

So I have all coaxes plugged in, and when I connect with the AC power cord, the LED lights up red, but then I lose all signals to each of the 4 lines plugged in to it. It works okay when not powered with AC, but once I plug in AC, the signal to the TV drops out.

Any ideas?

Apparently the component connection to Out 1/PWR IN has DC current power flowing thru it. Some components connected by coaxial cable have and provide DC power. Most do not though. Maybe yours does this and that is why it works. If so, you would not need the AC adapter connected to power the amplifier.

answer 3
I would double check to make sure you have the right line going to the "input". Cable from your antenna should be connected to input, and cable from the amplifier output should run to your device or TV. To some people this is counter intuitive. This may explain why you had signal when the amplifier was passive (not powered) but lost it when you plugged in the AC.

The way to test it to see if it is working properly is to disconnect one of the outbound cables. If the light stays on, then you know it's working. If the light goes out, then most likely the unit is defective and needs to replaced.
