Question 1

How do I retune my TV?

Accepted Answer

Performing a retune on your TV is a useful self diagnostic step you can attempt prior to instructing a company to attend site.
 
When performing a retune, you will need to navigate the menu on your TV. There will be a button on the TV remote, which will open the set up menu for the settings on the TV. Here you will find the option to either attempt an auto or manual tune. We suggest opting for the auto tune to start. Select the option for the auto tune and allow the TV the time to automaticlly input the frequencies into the TV. Hopefully, this will restore the correct TV channels and signal. 
 
If you still have an issue with the signal after peforming a retune. Then it is possible that there is an alternative issue with the equipment in situ.

Question 2

Why am I missing certain TV channels?

Accepted Answer

There are a number of reasons as to why you are missing certain TV channels.
 
The existing terrestrial TV aerial in situ may require aligning. It is possible that if the TV aerial is not aligned correctly, then certain channels can be missing. This is a simple repair and would involve an engineer attending site to realign the TV aerial. 
 
The existing terrestrial TV equipment may not have a clear line of sight to the transmitter. If the aerial does not have a clear line of sight, then this will affect the terrestrial TV signal and could explain why there are certain channels missing. This would require the aerial equipment to either be repositioned or provided with additional height, to achieve a clear line of sight to the transmitter. 
 
You may be experiencing issues with certain TV channels due to 4G interference. To rectify this issue, you would need to have a 4G filter installed to help filter out the 4G interference.
 
Finally, another reason as to why you may be missing certian channels is if your own TV equipment were faulty. The existing TV or internal receiver may have a fault and this could be causing issues with certain TV channels.

Question 3

What is causing my signal to deteriorate?

Accepted Answer

There are a number of reasons to explain why there has been a deterioration in your terrestrial TV signal. 
 
The existing aerial equipment in situ may be antiquated and in need of replacing. If your current aerial equipment has been in situ for a considerable duration, then it may be time to consider a new installation. A repair can look to be undertaken on an antiquated aerial, but the repairs may not suffice and depending on the age of the equipment, it may be beyond repair.
 
The aerial equipment may have some form of water ingression. If water has got into the TV aerial and or coaxial cable feed(s) then this will have an affect on your terrestrial TV signal. This can cause an on going issue with the TV signal or it may only affect the signal in poor or inclement weather. Over time this will contribute to a deterioration in your signal. If water has entered the aerial equipment, the simplest solution would likely be to replace the equipment that has water ingression, making sure that all equipment is water tight. 
 
The signal may be being affected by surrounding buildings, construction and or foilage. If the line of sight is being impeded by any of these, it will have an affect on the TV signal. The affects of surrounding buildings and construction are likley to be more permanent. The issues caused by surrounding tree foilage may have greater affect on the TV signal in the Spring and Summer months. To resolve this issue would involve either the relocation of the equipment or the installtion of additional or lrger mounting equipment to add more height.

Question 4

Why is my TV signal poor in bad weather?

Accepted Answer

The terrestrial TV signal can be affected more in poor or inclement weather conditions.
 
The existing TV aerial equipment on your property may not be secure. The equipment may have come loose over a period of time and in poor weather conditions, it is causing the TV aerial to move and lose signal. 
 
The aerial equipment in situ may be getting some form of water ingression. If water is getting into the TV aerial or the coaxial cable feed(s) then this will have an affect on your terrestrial TV signal. This can cause an on going issue with the TV signal or it may only affect the signal in poor or inclement weather. Over time this will contribute to a deterioration in your signal. If water has entered the aerial equipment, the simplest solution would likely be to replace the equipment that has water ingression, making sure that all equipment is water tight.

Question 5

What is the difference between Freeview TV and Freesat TV?

Accepted Answer

The difference between Freeview TV and Freesat TV is simple. 
 
Freeview TV is a service that is provided by having a TV aerial installed, which receives signal via a land transmitter. In order to watch Freeview TV you will need to have an aerial installed on your property and aligned to the land transmitter. You will either need a TV with the Freeview facility built in or a seperate Freeview receiver. Generally, most modern TV's now have the Freeview facility built in, thus avoiding the need to purchase a receiver.
 
Freesat TV is a service that is provided by having a satellite dish in situ, which receives a signal via a satellite. In order to watch Freesat TV, you will need to have a satellite dish installed on your property and aligned to the correct satellite. You will either need to have a TV that has the Freesat facility built in or a seperate Freesat receiver. Some modern TV's have the Freesat facility built in, if not, then a Freesat receiver needs to be purchased.

Question 6

What is the difference between Freesat TV and Sky TV?

Accepted Answer

The difference between Freesat TV and Sky TV is the service. 
 
The Freesat TV and Sky TV facilities are serviced from the same satellite. If your existing satellite dish is aligned for one of these services, then you can acquire the other. 
 
The Freesat TV facility is another way of obtaining the free to air channels, but instead of a TV aerial, it is via a satellite. The facility either has to be built within your TV or a Freesat receiver for you watch Freesat TV. 
 
The Sky TV service is a subscription based service, which you as a customer would have to approach Sky for, in relation to starting a subscription to watch their channels and service.

Question 7

What is an LNB?

Accepted Answer

A "Low-noise block downconverter" or LNB is the unit which is mounted on the satellite dish, which receives the signal used for satellite TV reception.

Question 8

Why are only certain channels missing on satellite TV?

Accepted Answer

Are you missing certian channels on your satellite TV service, but others are working fine? 
 
The issue could be due to a fault on the satellite LNB, or more specifically, an issue with a certain polarity. A polarity is a bank of channels and on satellite TV a section of channels are received via a certian polarity; horizontal high, horizontal low, vertical high and vertical low. 
 
If there is a fault on your satellite LNB, it could affect any one of these polarities either indivudually or collectivley. Any of the TV channels that are under the correspdeing polarity that is affected will be missing on your sarellite TV service.

Question 9

What is causing interference on my TV?

Accepted Answer

There are a number of reasons as to why you may be experiencing inteference on your TV.
 
Simply, poor signal strength and or poor signal quality can have an adverse affect on your TV signal and may manifest itself intermittently. Additionally, poor internal or external cabling, the latter of which may be subject to water ingression, can also contribute in interference. 
 
The internal distribution within your property could be causing interference on the TV signal. If the distribution equipment in situ is not adequate to service the amount of TV points within the property, this may result in poor signal and therefore interference. 
 
A faulty TV or receiver; if there is a fault on your own TV or an issue with your terrestrial or satellite receiver, this could agian manifest itself intermittently causing inteference on the signal.
 
Finally, one of the main causes of interference that affects the terrestrial TV (freeview) signal today relates to 4G Inteference.

Question 10

What is 4G Interference?

Accepted Answer

4G Interference is the mobile service (4G) that uses parts of the same radio spectrum, in bands of frequencies, as the digital TV service. The 800 MHz frequencies used by some 4G services accompany the frequencies used for Freeview TV. This may result in an adverse affect on the terrestrial TV signal. 
 
If there are levels of 4G interference affecting your TV signal - a 4G filter would need to be installed to help filter out the unwanted 4G inteference.
