What Can Causes Bad TV Reception?

 

No.1- Poor Quality Flylead

The most common problem and one of the easiest to fix by yourself is a faulty TV lead (Flylead). This connects from the antenna outlet to the TV's antenna input socket.

The type of lead that fails are the leads with a molded plug endsmolded ends lead. The wire that is used is very small gauge and they tend to break under the molding ends.

The other problem with this type of lead is that it is of a poor quality which can tend to pick up interference and this could cause the picture to breakup.

No. 2 - 4G (LTE)Interference.

The recent new 4G transmissions that have started on the Sunshine Coast since January 8th 2015 are being transmitted on a frequency that used to be one of our Digital TV channels, up until the restack in July 2014. The frequency is on Digital Channel 62 on 670MHz and close to the mobile towers the signal is extremely strong – up to twice as strong as the TV signal in some locations.

The problem this creates for residents is that the strong signal overpowers the TV signal in your TV antenna system and causes the channels to freeze or drop right out. The most common symptom is that it causes the picture to pixelate.

The Solution

We can install a filter on the antenna above the masthead amplifier which can fix the fault in some cases. As there been an increase 4G traffic we have found now in many cases it is better to replace the masthead amplifier and antenna with a 4G filter built in. If you are located close to a Telco Tower you may need to fit one or more filters as well.

The mobile phone towers affected are located right across the Sunshine Coast. There is a link to help you to show where the mobile towers are located.

You may be more effected if your TV antenna is pointing directly at one of these towers, in this case you will need a filter this out. Even if you are close to the tower you may still be affected. If you are well away from the towers you likely won't be affected for now but as more services are added you may find problems arise in the future.

 If you suspect that the TV reception is being affected by this interference you can call us on 5479 1999 and we can discuss the symptoms and send a technician if required.

 

No.3 - Picture is Breaking Up Anytime from 6pm while watching Brisbane VHF Channels On The Sunshine Coast.

This occurs mainly when we have warm to hot days and cool evenings and occurs usually in Autumn and Spring.

See Tropospheric propagation on wikipedia for those who technically minded. This will explain why this can occur. 

The Solution

A very simple cost effective solution, tune in and watch the Local TV Channels and not the Brisbane Stations.

 


No.4 - Some Local TV Channels are Breaking Up. 

 You may be tuned into the wrong repeater. This is a very common problem and we have found carrying out manual tune fixes many issues.
