Antiference MHK8LTE 8 Way Variable Gain Masthead Amplifier and Power Supply

(Updated as this product is under investigation by Trading Standards)In addition to the below, the PSU it is supplied with is a SMPS unit which is of a very poor quality, causes interference and is not safe, also the fuse that is fitted to the plug has Fake British Standards markings.I decided to fit a new Log Periodic (My favourite aerial)At the same time I fitted a Antiference 4 way mast amplifier so I can supply the signal to other rooms.Testing just the Aerial on it's own I had excellent signal level/quality.Then I connected up the 12v power supply inline, now Antiference have changed the design of their power supply, they used to come with a linear PSU (PF1)they are now including a Switch Mode PSU (PS12F) which is a tiny little thing and also does not have the ability to wall mount.As soon as I plugged this in, my signal was fluctuating, if I moved it I'd drop signal completely. If I turned on a HDMI device the signal would drop.If I put this power supply anywhere near the TV it would cause interference.I went outside and removed the Antiference mast head amplifier, went back inside and looped the PSU through (with a modified tap to stop the DC voltage) and the picture was fine as it was with just the Aerial connected to the TV, then I plugged the PSU back in to the mains and the problem started again.So just replaced it this morning with a Wolsey 4 Way Mast Amplifier which came with a Liner Power supply, signal is better than ever and no issues what so ever.I used WF100 throughout and Cabelcon compression F's, was a frustrating process as I really did not want to do that cable run again!Avoid this, it does not have any shielding, it is noisy and does not reject any interference. I think they are supplying these now due to stupid energy efficiency ratings and all that EuP nonsense. Not like a Linear 100ma PSU costs anything to run!

The product was okish to install, getting on the roof and clipping it on was not so easy, that's ok, its what I expected. And it has worked great for 44 days. I'm past refund time and I cant seem to find a way to contact the seller. The power supply has died, yup given up the ghost. Its only 3 amp I know, but really 44 days! Overall I was happy with the product, just not the fact that I have to piss around finding a 3 amp fuse, change it, see if that corrects it. Bit of a ball ache really. Not what I was expecting so soon after purchasing it. Oh, and no, nothing else blew in the house, and I switch everything off before I go out.

Both this model and it's Pro series sister model work very well. Was just what was needed to overcome/counter the effects of recent frequency clearances (aka signal strength reductions) at the Beckley transmitter on May 23rd. The green LED cannot be seen when the cover is closed; an unimportant point in 99% of situations.

Bought this to replace a masthead amp that had become waterlogged and failed. The Antiference unit works perfectly without any adjustment and looks well designed for the outdoor use.

I've fitted a few of these, but the one I got from amazon packed up a week later. Tv's stopped working in the block of flats, the tennants wasn't at all happy when I told them it would be a couple of days before I could fix it. Tried returning item, but had no luck. I bought replacement elsewhere and footed the cost.

Good item easy to install in the loft and works well

Happy to use this product easy to install

Very easy to install and solved the problems I was having with reception.
