Question: Will this work if I want to combine two OTA digital antennas to get better frequency? Bonus Question: Would an amplifier be a good add-value purchase if I'm trying to get better reception on a few channels?
Document: I read the good reviews and though it would work for me to combine signals from two antennas. It does not work! When both antennas are connected to the combiner and output to my TV, the channels from one antenna are clear but the other antenna's channels are totally disrupted. However, when we connect only one antenna, the channels are in excellent quality no matter which antenna.
This didn't work for me as a combiner. I was hoping to merge two antennas in the attic to strengthen the signal and add local over-the-air channels but it's no different than with only the first antenna. I'm positive I have it connected correctly.
I had an Eagle Aspen EASDTV2BUHF anntenna which was able to pull in a good chuck of the available channels when facing north, but two of the channels i wanted were coming from the south so I thought I would put up a second one (back to back configuration) to get the additional channels. I used this to combine them and it worked perfectly. I now get all the channels and they are crystal clear. There are more expensive devices out there that basically do exactly what this little guy does.
This combiner allows to take signals from two HDTV antennas and combine them before connecting them to a signal amplifier. It definitely makes an improvement you can see with higher signal strength at the TV. It works for me so I'm glad I got it.
I was hoping to combine the signals from two roof antennas pointed in opposite directions and expected to get more off the air stations. However the signals from each antenna were better when not run thru the combiner. I guess the signals phase each other out by being combined and the end result was a weaker signal and fewer channels. Not happy with the end result and don't know what to do about it.
Hello alli got this as a way to combine two indoor antenna in hopes of getting a local station, and while the plan did not work, i will say i am pleased with what i got and it did work very well so with the purchase i am happy i got it and if i ever do get an outside antenna i could use this to split the signal to two tvs
I bought this to combine two antennas. I already had a splitter I was using and thought I would give this one a try as it looked to be a little better quality and mentioned it was designed to be used as either a splitter or a combiner.I am happy with the results as it is working better than my old splitter I was using.
Just got this today, connected both antennas to combiner, connected combiner to amp, rescanned and now I'm getting 57 channels which is 9 more then I was getting with the LEAF alone. Channels 2 - 10 were the ones I didn't get with the LEAF and my guess was a dipole would be the best supplement for the LEAF and in my case IT IS! The RCA pulls 2, 4, 5, 6, 7 and 10 but only with the amp in place.
I live between 2 cities, about 40 miles from each. I used this to combine 2 different HDTV antennas in hopes of receiving TV stations from both. For the most part, I think it worked, I now have more channels than ever with higher signal strengths than I've seen before. I still get mild breakup on occasion, but things are much better overall.
I purchased this product to combine UHF and VHF in house antenna signals. I have a VHF source that is coming from a totally different direction than the rest of my UHF channels, so I needed a solution to combine two antennas. The antennas are upstairs and the unamplified coaxial splitter box is in the basement. Once I used the combiner, I attached theViewsonics VSMA-611C 1-Port 15dB Cable TV HDTV Signal Booster / Amplifier (Retail Package)to boost the signal strength from the two antennas.
Answer: Yes, that is exactly what I am using one of the two I bought to do. And, yes, an amplifier will help you be able to tune in weaker channels as well. I am using an amplifier to do that as well, without it sometimes one of my weaker channels will drop out ... and if that happens at the beginning of a show time it will cause my DVR to skip recording the entire show. So I use the combiner to connect two OTA antennas pointed in different directions and then boost the signal strength. Hope that helps you to solve your problems.
