FAQ

At WeFitAerials, we are here to help you with all issues and questions that surround TV aerial installation and repair. Below we have listed 12 of the most commonly asked TV aerial queries in this helpful TV aerial installation FAQ page.

1. I have re-tuned and I have the wrong region or Welsh TV. Why?

The channel frequencies have been moved, so your TV aerial may be picking up a signal from an alternate transmitter. Winter hill (Granada) and Moel-y-Parc (Wales) are now very close together, so the only option may be to swap your aerial for one with a narrow beam width and attenuate out the unwanted signal. You could try unplugging the aerial then start a re-tune, then insert the aerial when the regional channels are to be stored.

2. I have water in my aerial wire / coaxial cable what should I do?

The aerial downlead will need replacing, possibly the aerial too. To speak one of our TV aerial experts about this matter please call 0800 0565177.

3. Can I run more than one TV/Freeview box off my existing aerial?

It all depends on signal strength. If the signal is strong enough a splitter can be used to run extra TV points. If the signal is low, then an amplifier can be installed to run multiple TV aerial points from one aerial.

4. How do you bring a TV aerial wire into the house?

There are a number of ways to do this. On a mature property, our WeFitAerials engineer would usually drill through an external wall with a 10mm drill, then run the aerial lead through a grommet on the internal wall and sealant on the exterior. If you have wood windows we can bring the aerial wire through the frame, but as the majority of properties now have PVC frames the wall option is preferred.

5. Can I have a plug in aerial socket fitted?

Yes, there are a few different types of aerial sockets. There are surface mounted ones that screw to the skirting board, or flush sockets that go onto a back-box that is screwed to the wall or cut into the plaster board. All these options are neat when installed. Please call for a quote on 0800 0565177.

6. My digital TV aerial has fallen down off its brackets on the chimney, will it still receive a good reception?

If it is facing the transmitter it will probably still receive some channels, but it is advisable to get a WeFitAerials engineer out to repair the aerial problem before any more damage is done to the aerial or your property.

7. My picture on my digital TV is breaking up/going into squares/pixellating, is this my aerial?

The majority of time yes, it is an aerial fault. Sometimes it can be a tuner problem in the digital TV or digi-box. If it is an aerial problem, it usually points to a weak or poor signal. At WeFitAerials all our engineers have spectrum analyser meters to check the signal strength.

8. I have some channels missing on Freeview, why is this?

The signals are transmitted in what is called a multiplex or mux. And each one carries a number of channels. If any of these are weaker than the signal level required for the digital TV/Freeview box to lock onto, the channels carried in that mux will be missing, resulting in channels missing on your Freeview. This then points to an aerial fault.

9. Can I run more than one satellite receiver off my dish?

Yes, but you have to have a multiple feed LNB on your satellite dish. They come as quad (4 way) or octo (8 way). You have to remember, if you are running a PVR box (recorder), the box will require a twin feed from the dish. A standard box will only require a single cable.

10. What is a wideband aerial?

TV signals are transmitted in a frequency band known as UHF. A wideband aerial covers the whole band width channels 21-69. Different transmitters use different parts of the bandwidth, so you can also have what are called grouped aerials. They are split into four different groups and are identified by letter and colour:

• A group. Red. Channels 21-37.
• B group. Yellow. Channels 35-53.
• C/D group. Green. Channels 48-68.
• Wideband. Black. Channels 21-69.

11. What is the difference between a masthead amplifier and a setback amplifier?

A masthead amplifier usually goes up on the aerial mast, so you can run TV aerial cables from the aerial to multiple points. The amp has to be powered by a 12volt power supply that is installed internally at one of the aerial points. Whereas a setback amp is an amplifier that goes internally and is usually plugged into a mains socket. However, there are a few amps that also run off a 12volt supply.

12. What is an omni directional DAB/FM aerial?

DAB is digital radio. FM is analogue radio. Omni directional means the aerial will pick up from all around, so it can take radio signals from different transmitters where the reception is good enough. If you are in a fringe reception area, WeFitAerials recommends a multi element directional aerial, primarily focused to one transmitter, to achieve maximum signal gain.
