Amplifier, Cable TV RF Broadband 8dB Gain Four Output 5-1002Mhz w/ Power Adapter

This has been working well for many months. Cox-cable put one in my attic that shorted out, apparently from overheating. I routed all of the cables down into the living space to avoid that problem, and the amp is working fine. I have no idea how it would fare in a summer-heated attic.

I had a strange issue with my Xfinity service where I use TIVO and cable card. On certain HD channels I would see pixelation and channel degradation to the point where it was un-watchable. I thought it was my TIVO Bolt or even the cable card which Xfinity provides but since the signal problem only affected specific channels I determined this had to be the incoming signal.So, as a last resort before calling Xfinity (ugh) I decided to try this amplifier and install where it comes into my house. I also bought new 6 foot coax cables and some 75ohm terminators to cap off any unused ports around the house as well as on this amplifier. If you don't cap the empty ports off they can act as an antenna and could result in more noise on the channels or even a visit from Comcast due to excessive broadcasts into the air. FCC requires Comcast and others to prevent this as it could interfere with other users systems. I figured for a few bucks I would just purchase a pack of 5 terminators and cap off the unused ports and avoid any issues plus do the job correctly. They simply screw on to the coax port....nothing complicated.I removed my existing splitter and installed this amplifier (which is also a splitter), a couple of terminators for unused ports and connected the incoming Comcast cable and the power adapter. This amplifier DOES REQUIRE an OUTLET nearby as it is powered to help deal with less than ideal incoming signals from Comcast (or whatever service you have). I've seen a lot of posts about this issue from many people using various services so this is NOT just a comcast issue.Keep in mind, this will boost the INCOMING SIGNAL to compensate for signal loss but it CANNOT FIX AN ALREADY BAD INCOMING SIGNAL. It will simply boost whatever is coming into your house. If the signal is low or poor for other reasons like bad cabling from their incoming box to your house then this likely won't do much other than boost a bad signal. For our issue, it was specific HD channels during evening hours when usage was likely higher on Comcast's systems and there was no indication the signal coming into our house was bad across the board. Only for a handful of channels. I don't know if Comcast can do anything about specific channel's signals or not but I didn't want to deal with them if I could avoid it as involving them is always a headache and they rarely make anything better and often create other problems in my experience. They always want to blame our cabling or router or whatever and I can do the same things their technicians would do in order to troubleshoot issues. In this case, I seem to have found the solution thanks to other postings so I wanted to detail my issue too.Ideally, it would be nice if customers could call Comcast and get them to fix it but in many posts I've seen their solution is to do exactly the same thing...install this amplifier, terminators, etc. to resolve the issues for customers. Clearly, they want to avoid having to run NEW OUTSIDE CABLING and digging up a yard and so on and I am sure most customers don't want that either unless the cabling is found to be truly bad, broken, cut, etc. Then it is worth it but for this random pixelation issue on only certain HD channels at certain times of the day this seems to resolve it. So far we have not seen any additional pixelation issues on the problem channels and our HD channels are as clear as ever.Again, buy this amplifier, a 5 or 10 pack of 75 ohms terminators to cap any unused ports in your house (i.e. where cable ports are in your rooms) as well as on the amplifier itself and make sure you have an outlet nearby to power the amplifier. The best location is where it comes into the house.Good luck!

Should have ordered a more powerful booster but this one will do. Didn’t pick up the local channel that I was targeting but it still works fine for the other channels

So the previous owner of the house left 4 cables drawn from the roof to a dish down to areas of the house. This amplifier seemed a good for it. I would prefer just a single output line I could split 4 ways after entering the home, but this seemed the best bang-for-buck. I used one coax cable to push the 5V power up to the aerial I put up, and 3 others to drop down. I wasn't disappointed. The signal comes in clear to all the TV's in the home. We love it because there's something special about local channels and news. So far have it mounted outside in the elements and performing good. If you're interested, I used the ClearStream 4 antenna.

Only 1.5db gain on fios digital (not 7.5db), if you look at the data sheet channels that use 550Mhz+ only have 1.5db gain or less. I used temporarily until I had my ONT replaced. Do not recommend for fios or use the 2 output model to give you more gain (+5.5db). You have to put all the STBs and modem on on outputs for MoCA to pass so unless you only have one STB and internet the 2-port will not work at all. Stay away.

I have Xfinity and have cable, internet, and land line phone. The signal for the tv was going in and out with this the signal was strong. The only thing buy the caps to the port if you don’t use all of them. I understand that used port signal can come thru the use used port.

The amplifier worked perfectly when I first purchased it. Then just one day it quit. The power supply still worked but the unit quit amplifying and I started receiving terrible signal if any at all. I went back to my original RCA amplifier and everything works perfectly now. I do not recommend this unit

My cable modem can't ever get full throughput without an amp. I've got a situation where I could use a single port 15dB amp with downstream splitters, or use this amp with few or no splitters. It's DOCSIS 3.0 compatible, so also ready for the new high speed stuff if it's in your area or coming soon.I tested fully, and found this four output amp is compatible with MoCA between output ports, meaning devices on each port can talk to each other. I wasn't sure what to expect for MoCA, thinking this amp might be better suited to a duplex or fourplex home situation.Note that Antronix amps can be powered remotely by sharing an output with a device if you purchase their power inserter ARPI-2000. This is handy if you don't have a power plug near the amp and can't run another cable just for power.If you don't use all four outputs, you need to get some 75 ohm terminators like these for the unused ports. They're only a few dollars for a 10-pack.
