    Picture Perfect
    Having purchased a new 60” smart TV to replace my dead 50” non smart TV, I was struggling with quite a few of the free view digital channels, many of them being pixelated with poor signal. The smart TV doesn’t seem to be as forgiving as a non smart TV when it comes to aerial signal strength. A little bit of research and I purchased this ‘SLX 27824HSR 8 way signal booster’ to replace an old 8 way ‘TV Link’ that I had setup in the attic (all my aerial cables are terminated in the attic) to run sky throughout the house. I no longer have sky. A quick re-tuning of the TV channels, and the channels I was previously struggling with now have a much better signal strength, picture perfect with zero pixelation.It’s worth noting that I have a good quality external digital aerial attached to my chimney, and the coaxial cable runs directly into the attic to the booster.Extremely happy with this purchase, which I highly recommend.The SLX 27824BMR is a very similar booster but with IR bypass which will allow a signal to be passed back through the unit to the base unit.

      Got this to replace an old booster and splitter as we have 2 TV's and 2 HDHomerun Quatro's on a single aerial. The previous adapters used to work years ago supplying 3 TV's with each also having Freeview boxes attached.
      But the adapters/boosters were no longer adequate for 2 TV's, so got this to replace and it works perfectly, connected directly to my aerial input then off to 3 devices with the 4th piggy backed off the 3rd connection using a splitter.
      Picture quality is excellent and no longer breaking up on hd and other channels.
      Well worth paying the extra for a decent product.

      Amplifier works perfectly, with 100% signal strength and 100% signal quality; I live on the edge of the Tacolneston TV transmitter area and cannot receive any signal without an amplifier.
      Just two criticisms, not of the amplifier itself: (1) it did not work when I plugged it in - no green LED showing. I checked the 3 amp fuse in the plug, as supplied, which turned out to be dead, so I replaced it and the device worked perfectly. These things happen. (2) The print on the label on the Amazon delivery box was rather faint and the assistant at the pickup point had difficulty scanning the QR Code - it was on the verge of being set back to the merchant - until on the fourth attempt with a different scanner, she could confirm the code. The merchant I used needs to get a new printer cartridge for their labels!

      Our original setup was 5 TVs running from and old 6 output aerial amplifier that was "digital compatible", distributing the signal from a chimney mounted aerial, the local transmitter being only about a mile away as the crow flies, (over a hill), 3 tvs were always used with virgin boxes or playstation 4, so not using the aerial feed, but 2 tvs (which we used less often and were fed from the aerial), had developed issues with pixelation or just zero reception on various channels, but didn't display "no signal", I started looking at aerials and amplifiers, and noticed that many said they had 4G filters built in, unsure if the issue was the aerial, the aerial drop cable, the amplifier or 4G interference, and not fancying climbing onto the roof I decided I'd take a punt on a new amplifier with built in 4G filter. Results are: all tvs work happily, with older (non hd tuner) tvs receiving 94 freeview channels and the newer ones receiving in excess of 120 (including the freeview hd ones).
      Money well spent, I still don't know if the issue was with the old amp or with 4G interference, but I do know that it is fixed now., of course if it hadn't worked, a trip up the ladder would have been required!.

      Bought this as a replacement for a similar product (SLx 6 output) that had failed after about 18 years of faithful service.

      The new device is substantially the same, except with more outputs, and with a boosted output to allow daisy-chaining of further amplifiers (for a larger building distribution solution).

      Signal strength is now perfect, with the boosted output actually over-driving one device (so I switched to one of the non-boosted connections).

      I'd recommend this device to anyone who needs a single box solution to a multi-room antenna system. Though, if I were planning my solution again, I'd probably go for F-Connectors instead of UHF co-axial connectors (more hassle to initially fit, but better long-term reliability, however, I wasn't going to re-wire my whole house, so I went for a drop-in replacement, and kept things as they were).

      Pros:
      Easy to install, does exactly what it says it does.
      Signal strength (on normal outputs) significantly better then the old amp, even when it was working (assuming this is because it is now designed from the ground-up for digital TV, whereas my old amp pre-dated ubiquitous DVB-T)
      Integral 4G (Clear at 800) filter simplifies things, though, in my case, I'm not sure if I need one, but at least if they install a mast in the future, I won't suddenly lose my TV.
      Built-in masthead power is a benefit, if you need a masthead amplifier.
      Compact design, easy to mount on a beam in any loft.

      Cons:
      Documentation has both shrunk, and become a lot less descriptive - the included terminator is very important (to terminate the boosted output if it is not in use) but is not mentioned in the included documentation, and you need to look at previous versions of the documentation to find out what it is, and how important it is. I'm not sure the paper savings by making the documentation smaller justify the increased difficulty!
      Whilst this is exactly what I needed, I'd suggest the F-Connector version of the same product for new builds (learn from my mistakes, people!)

      After moving into a new (old) house, I discovered the aerial was missing! A new one was promptly purchased, but signal was poor. Along came this device - I plugged in 5 TVs and then when connected to the aerial, it did a great job getting strong signal!

      Signal, both TV and mobile can be patchy where I live and after losing 50% of the channels on my Freeview box when I did a rescan, I decided enough was enough.

      My options were to get a whole new aerial or a signal booster like this, and since that was the quicker, cheaper option, I figured I'd try it first.

      I was pleasantly surprised to find that not only did it restore the channels that had been lost, we also got several new ones and all had a higher quality according to the set to box - confirmed by them not breaking up when watching any more.

      The only downside is the audible whistling that the unit makes, which could mean it has cheap capacitors, which in turn could affect its lifespan.

      All in all though, happy so far (6 months later).
