Channel Vision Splitter/Combiner, 1GHz, DC, 4-Way

I am unsure about this product as a combiner. I used it to combine 2 antennas and the first day it worked but the next day my signals were weaker and couldn’t watch some channels.

I got this to use as a 4way antenna combiner (3 antennas and 1 cable (starter tv cable package included with my internet service.)) Each placed antenna in a different direction and orientation picks up a different set of channels. Combined I get most of the channels from all the antenna inputs clearly during a channel scan. At first I thought this didn't work at all. I couldn't get any channels, or any image through this. It wasn't even recognizing any cable channels during a scan. I tried various combinations with no success. 1 of my 3 antennas has no amplifier, the other two have an amplifier that can be turned off. When I finally tried just the cable, and antenna with no amp I got scan results. As soon as I plugged in a 2nd antenna with amplifier on I got nothing again (didn't see cable channels either.) I am not sure why this is the case, but when I turned off the amplifier on both antennas I could connect all 4 input sources with successful scan, but turning on either amplifier blocked the signals of all the input devices.

After installing this device, I got a good TV picture , the TV stations in my area are transmitting between 515.000 MHz to 599MHz .this is in the UHF band. After one week of it failed, in this way " no picture and then a picture." . I removed this device and put pack my Linear 2512 ChannelPlus DC & IR Passing 2-Way Splitter/Combiner, and my TV stations came back.

Channel Vision has a reputation for high quality, and after 6 months of use, I have to agree. I hooked this simple splitter up under my house, and it's been flawless ever since. I didn't need to include a signal booster, and have no problems with basic, digital, and cable modem signals. Channel Vision has one of the lowest signal (decibel) losses of any 4-way splitter. I even left one port open to the weather for a couple months, and recently switched my cable modem to it, and it works great :)

Exactly what I needed worked perfect

When added the combiner dropped channels. When removed channels worked again.
