Product overview

• Ideal for use when aerial signal is too strong• Universal - fine tune the attenuation to get a perfect picture• Ideal for use when the level of attenuation is unknown• 0-20dB continuous variable attenuation• 75Ω impedance• Frequency range 5-1000MHz• Insertion loss less than 2dB

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.

Rated 5 out of 5 by from Did the trick! Several freeview channels when viewed via my digital recorder box were unwatchable, but perfect when aerial (rooftop) was plugged directly into tv. After learning that this was probably due to the signal being too strong for the box I purchased this attenuator. The aerial plug goes into one side of the attenuator and the other side of it plugs into the box and, after a little bit of twiddling, all channels were once again watchable. Got this from Maplins because of their reliability but it would be a good idea to shop around a bit for this item because prices do vary!

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.

Ref Variable Aerial Attenuator Order Code: A03HT - does this work where the signal is too low ?
Asked by: Neville
No, you would need an amplifier for this purpose.

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

Yes the product does support that.
