Signals that are too stong can affect the clarity of your TV signal as much as too weak a signal. When the analogue signal is switched off in the UK, the digital signal will be boosted from its current rate. This may mean that you had perfect signal before the switchover and then your digital picture breaks up or mosaics, this is where the Variable Aerial Attenuator comes in. Its adjustable tuning means you need not worry about which attenuator to purchase, this will cover the full range that will be required.

Will this restore lost channels after "weak or no signal" message on tv. TV working perfectly before this. Live near London. Have Samsung tv.

I am in a complex with a shared aerial. Good signal to TV but Youview box not finding all channels.  Don't know if I should try attenuator or booster? Is there a way to measure signal strength.

Just bought one of these. As there are no instructions can you advise which way you turn the adjuster to increase attenuation

Asked by: Stuey
This will generally be in a clockwise rotation.

AS I had lost some digital stations due to low signal strength I have installed a signal booster. This has allowed me to access lost channels, but I now have lost some previously obtainable ones which already had adequate signal. I understand this is likely to be because the signal is now too strong for these and wonder can I also fit an attenuator, and should it be before or after the booster( this is near the TV as suggested on the instructions)
Asked by: Sue Wood
You could fit an attenuator after the booster, this may improve the situation.

Please advise as to whether this product is suitable for use with Cable TV or is it just for standard (roof aerial) TV. Also, are the connectors screw (F) type or standard RF?
Asked by: Ken Sherrocks
This is for standard tv (not cable)connections are via coax plugs
