The amplifier was placed in the loft with the aerial and the power supply connected to the lounge TV aerial point. Works a treat. It saved me having to mess about with adding a 240 Volt supply in the loft from a ring main to supply an alternative amp - lots of work avoided !. The 12 volt supply which is included does the job nicely. The amplifier "gain" can be adjusted - this is done via a small plastic adjuster in the amp itself. However I wouldn't recommend turning it down to "minimum", the amplifier will become unstable and does not provide the signals you want. Best to leave it as supplied (mine was 2/3rds up). Great product though and did the job well !. ### ⭐⭐⭐ 3.0 out of 5 stars A real solution to poor signal UPDATE: did not stand the test of time. *by S***E on Reviewed in the United Kingdom on 2 March 2016* Delivery should never be part of a review; the review is for the product only.Packaging.The product arrived in a Cardboard Box, Id say mediocre packaging, no bubble wrap or protective packaging.Product Review.I moved into a new house in 2013 at the point analogue signal was switched off and digital was your only choice unless you took SKY or VIRGIN.I live quite rural and have to rely on a local redistribution signal, as I am on the border of getting the main broadcast signal in South Wales.The previous owner had made off with the aerial on the roof, and as I am a tight ass, I decided fit one myself in the loft! Who wants to pay for a TV engineer when you can do it twice as good at a 1/3 the price! (if you fall off your ladder don’t blame me :D)IMPORTANT! You should always get an aerial that will receive the best possible amount of signal before you make any other adjustments, so I fitted a very high gain digital aerial with 4G LTE cancelling tech..But the best I could get was breakup during the day and signal loss in the evening, no matter how much I moved it around or pointed at the moon it would not work any better..DO NOT waste your money on boosters that you plug into the socket behind your TV, they very rarely if ever work.Step in Masthead Amplifier, So first of all it is provided with a wiring diagram, which at first glance you would disbelief how the wiring works, but trust me believe it.. you also get some f plugs to complete your wiring, so I wired it it, and I went from 32 glitch channels to 91 full strength (HD too) Channels working 24/7 flawlessly!Now I had 2 runs of RF COAX running about 20 meters each and a 3rd at about 10 meters, I found I could not power all three lines with this if I did it I would lose signal at one point, so I have used the 2 x 20 meters which is fine for my needs, but some of you may need to consider a more powerful DC feed for longer runs.While F Plugs are provided they are for good quality cable, they wont fit thinner cables, also I found the connection on the PSU to be a bit lose at best so I had to make sure the exposed copper on the ends of the cables was S shaped to make sure a point of contact was constant, the PSU provides confirmation that a signal is working with a Green LED which lights up when a signal is present.Overall it’s a great product that solved my needs and gave me full signal, and I can finally cancel my sky sub. And move to Freeview and Streaming.It lost a star for its product packaging being a bit cheap and poor, also for lack of power on longer runs and lose connection.UPDATE:So i ended up returning this as basically it just kept losing power for no reason, and failing to keep a strong signal, ive lowered my review to 3 stars, because of fault issue. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Works and is good value for *by N***. on Reviewed in the United Kingdom on 15 December 2016* Works and is good value for money --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/59169635-4-way-tv-aerial-masthead-amplifier-black-ma20-4](https://www.desertcart.tn/products/59169635-4-way-tv-aerial-masthead-amplifier-black-ma20-4) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-09*
