Review on PACOSO Amplified HD Digital TV Antenna: Long Range with Signal Booster for Full 📡 HD 1080P 4K TVs - 50-85 Miles Range, Detachable, Indoor Use with Longer Coax Cable by Dustin Berry

I have a cable in my house that was installed by Comcast. For at least a year I was able to use a cheap 2-way passive splitter and watch both TVs. via TiVo Premiere and 25Mbps internet access (nice). But recently, for unknown reasons, the internet signal became too weak to go online. TiVo continued to work as it doesn't seem to need such a strong signal. If I removed the splitter and plugged the cable directly into my cable modem, the internet would work. But I also want to watch TV! Every call to Comcast ended with them wanting to send a tech while charging me $50 for a home visit. Although I have had experienced and professional Comcast Tech people in the past, I have found that most of them do nothing but turn my cable modem on and off and usually leave without a solution. So I set out to clarify the obvious. I examined the cable near my house. He looked in excellent physical condition. In the room I exchanged the splinters. I changed cables. No improvements. But after searching the internet I finally learned something new: I CAN CHECK THE STRENGTH OF THE SIGNAL MYSELF WITH THE DEVICE I HAVE! My TiVo Premiere and probably every DVR has a submenu that shows signal strength. I found out mine was 67. On a scale out of 100, 67 is not very good. And my Zoom 5341 cable modem (latest and DOCSIS 3.0) also has a signal strength indicator. I assume that almost every cable modem will have this function. Simply open MS Explorer, enter 192.168.100.1 as the address and you will be taken to the access page. Sign in and the signal strength will be displayed in the submenu. Mine was in the -5.5 to -6.5 range on all channels. abominable. So I bought and installed BDA-S4. Signal strength on TiVo went from 67 to 89! Good. But the cable modem reported no signal at all - zero. I called Comcast again and, knowing this, emphasized how poor my signal strength was for both devices. The technician on the phone was impressed that I could read the signals. For the first time I felt like I was in control of the situation. He tried to fix it by giving me regular "on on off" workouts and a reset but to no avail. Each time I checked the signals and told him how bad the signal was. In the end he said he needed to speak to another technician and just disappeared. He didn't hang up but must have been gone at least 30 minutes. I never spoke to him again. But what happened is that the internet suddenly started working! My signal went from -6.0 to +6.0. Very beautiful. Apparently Comcast did something at their home office to fix my signal. I didn't have to visit a technician at all. I still use my BDA-S4, although I probably won't need it in the long run. It looks very well made and efficient. Conclusion: Before you buy an amplifier, CHECK THE SIGNAL STRENGTH yourself. Your DVR and cable modem should already have this feature, you just need to know where to look. Much luck!
