No instructions but was fairly easy to install. I can now run 3 TV's with a perfect picture off an old aerial that used to run just 1 TV and a picture that would break up regularly when the atmospheric conditions were bad. I fixed mine in the loft as I have a power supply up there, but you can connect the PSU behind your TV. First of all connect the PSU outlet to some TV cable and then connect it to one of the 4 outlets from the amp, when the PSU is plugged in it boosts power to the amp and down the other 3 TV connections, so effectively it gives you the facility to run cables to 3 TV's from the 4 outlets. The cable from your aerial connects to the inlet of the amp. There are no "F" connections supplied so you will need to buy a pack of at least 8. Two for the aerial cable and four for the TV outlets and two for the PSU. If you don't know how to fit the"F" connectors just youtube it like I did. At first I didn't have a clue how to install this kit but after looking at the reviews I was able to do it and saved myself a couple of hundred quid in the process, so thanks for the reviews guys. Review: Works well but you may well need more pieces. - I had an old analogue aerial mounted low on the eaves and a Maxview 6 way splitter in the loft. All worked well and we received all the freeview channels and HD. Due to an extension being built we had to move the aerial up to the chimney and we took the opportunity to upgrade to a 4G digital aerial. Unfortunately the move took the aerial line of sight into a dense tree line and we lost a lot of channels including the HD ones. The aerial fitter said the existing Maxview booster did not have a high enough gain and he tried a Wolsey WFAV 425 which seemed to cure the problem. However he wanted a further £68 for this amplifier and I had seen it on desertcart for £18 so I politely declined and bought it myself. As other reviewers have identified, this does not come with any leads or F connectors so it was not a straight forward swap. There were also no instructions supplied but I expected this after reading the other reviews. The old Maxview splitter was aerial in with a coax connector and 6 coax outputs, the PSU was integrated. With the Wolsey set up the PSU is separate and splits one of the outputs so the PSU can be mounted anywhere between the TV and and the amplifier. It then powers the other 3 outputs via the amplifier. However this means that you will need an extra cable for the one that is split. Also all connections are F type so if you have coax connectors you will either need to replace the connectors with F type or do as I did and use convertors (there a potentially 7 connections to convert if all 4 outputs are used). Another minor point is that while the PSU comes supplied with two fixing screws the amplifier does not. Once I had placed a further order for the missing parts I fitted the unit in the loft with the PSU adjacent to the the amplifier and everything worked first time (I did not have to adjust the gain as other reviewers had). I split the cable going to the furthest and most basic TV and this now has 95-100% signal on all channels which it never had before. Our main TV has now regained the lost HD channels. I would give this unit 5 starts if it came with instructions, a spare lead, enough fixing screws and possible convertor connectors. However it has a well deserved 4 stars for doing what it does at such a reasonable price. ## Features - F-Connector Masthead Amplifier and Power Supply Kit - 1 Input 4 Output - 10-25 dB Variable Gain - Weatherproof housing.

I've never known of one to go on fire or anything like that. They derive their 12V suply from a separate power unit which is nearly always 'fused'. i.e the 'mains' transformer inside the PSU is designed to go open circuit should excess current flow in the windings beyond a know safety limit. **Q: How is the unit powered** A: It has a 3 pin plug so you need to find a power point, I cheated as I installed mine in the loft, the loft only had lighting circuits that are 5 amps, this needs less than 1 amp so I wired it into the lighting circuit, by putting a socket on the lighting circuit, illegal I know but I don't run anything else from this socket so it's ok ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent kit, good value for money. *by L***9 on 12 January 2015* Excellent kit, good value for money.
