SLx Digidome HD TV Aerial Kit

The Why!

I'll be honest, I don't like TV Aerials. I think they are ugly and detract from a good looking house. I used to have a TV Aerial in the loft but after turning digital the quality of the signal went down.

I used freesat for a while as the dish angle was almost flat to the wall and was in a place out of sight.

After having an extension on the rear of the property I needed an Aerial for the TV and didn't want to run a cable from the front of the house to the back and this kit looked like a good compromise.

So I ordered mine from Amazon, this is quite convenient for delivery speed and as is quite often the case, they were competitive on price at the time I ordered.

The kit comprises of;

The Aerial and Wall Bracket
Bolts and Wall Plugs to secure the bracket to the wall
10m of Coaxial Cable
Cable Clips
Power booster
f Type Connectors
Set of instructions

So what's in the cardboard box

Installing it

As always remember to plan, make a drink or even better get someone to make one for you. Once you have your drink take your time to read the instructions and familiarise yourself with the contents of the box.

Things to consider.

It states that it's omni directional but, there are two arrows that you need to align with your nearest transmitter. Check the BBC Fault Finder, enter your postcode and house number and it will show you the direction you need to be pointing.
Where are you going to position your booster, I have power in the loft near to where I installed the Aerial so have put mine up there. There was also an internal aerial cable from the loft down to the TV socket on the wall so didn't need all 10m but you can run it down the outside and in through the wall.
You may need a normal TV Aerial Connector depending on the what your TV/Digibox has on the rear.
If you have never connected F type or normal TV Aerial Connectors to cable, give it a quick google, it's not difficult, the key thing is making sure the outer braiding doesn't touch the central core as this will impact the signal.
Are you confident up a ladder? Sounds a daft question? You knew you needed a ladder to install it but how comfortable are you using a drill at height? If in doubt get an Aerial Fitter or a Competent Handyman to install it for you

Conclusion

I think this is amazing, it looks so small and light that you doubt it's up to the job.
We managed to get 100% signal strength and 95% Quality
Discreet and compact, less obvious than an TV Aerial

4G and 5G Filter
Everything you need in the kit, whether upgrading existing Aerial or a new install
Use the BBC Fault Finder for your nearest transmitter direction

Using it

Once you have installed it you will need to check the Strength/Quality of the signal. Most TV's/Digiboxes have a section in the settings that allows you to check the signal quality and/or strength. Give it a check, if you think it needs a tweek I suggest getting your phone on handsfree and talk to someone watching the reading while you give the aerial a slight turn.

Cable Tidy

Remember to clip the cables to the wall but don't crush them or damage the outer. Water ingress will impact the signal very quickly. In some cases the water can reach the electrical product at the bottom end of the run
