## Description

Boost TV picture quality and reception with this 4-way signal amplifier. Designed to distribute digital and analog signals, enhancing performance in poor reception areas.

Review: Replaced a life-expired similar product, and does a great job. - We've long had issues getting the strongest TV signal to our house. We live in a suburban area, in amongst a number of very tall trees in the neighbourhood that, depending on the weather conditions, can play havok with our TV picture. We live in Derby which is about equidistant between the East Midlands transmitter at Waltham (28.3 miles away) and the West Midlands transmitter at Sutton Coldfield (27.9 miles away). Ideally we'd want the East Midlands transmitter as Derby generally features on the East Midlands news/sport programmes. We're on to our third TV aerial since we moved here 10 years ago, the first two pointing towards Waltham but would always be at the mercy of the swaying trees as to whether we got a stable picture. About four years ago we had a new aerial fitted, a pretty substantial thing that we decided to have point towards Sutton Coldfield. Through all of this we employed a 4 into 1 splitter booster box. The aerial comes into the loft and then I split the signal into four seperate cables that head off around the house. The splitter box deals with that, and boosts the signal at the same time. Recently, we'd started to suffer from a serious reduction in our TV signal quality. I wondered if it was down to the booster box coming to the end of its life, so I decided to replace it with a very similar product, which so happened to be the best selling product of its type on desertcart. It also featured a 4G filter which helps with any interference on the frequencies 4G use. The TV signal was better than it was, certainly, however the issue turned out to be a new 5G antenna that was installed close to my house a year ago but only got commissioned within the last few weeks. I did a bit of research and found that 5G antennas can be responsible for TV signal break-ups. And the 4G filter that was in this new TV booster splitter would have no effect as it's a different frequency entirely. In fact, I found that the booster box, necessary to get any kind of TV signal to our house, could even take the 5G signal and boost that as well causing increased interferrence. So, I needed a 5G filter as well, which I bought from desertcart. Between that filter, and this booster splitter with 4G filter I've covered all bases. My TV signal is now absolutely spot on. Although this splitter box wasn't the actual solution to the problem that I was having, it's still an improvement over the splitter box I was using and If a general splitter/booster is what you're looking for then I certainly recommend it.
Review: Nice booster/Splitter. - Since I no longer have freeview this no longer works for me, but it has worked well for me, just what I needed, nice and solid, the sockets are a bit tight but not a problem, better than the old one. I tend not to mount these things, it does have holes in the back, easy to instal, you just plug it in.

### ⭐⭐⭐⭐ Works ok most the time

Works well most the time but sometimes it won’t let me change the input without disconnecting and reconnecting the cables.
