Antop’s New Generation Digital Technology

The built-in Smartpass Amplifier, an exclusive technology offered only by Antop, uses an all-in-one design to allow an easier connection and deliver the correct balance between short and long range reception. AntopP was the first antenna manufacturer to include a built-in 4G FILTER in all their products to block 3G and 4G wireless signals to ensure noise-free digital TV reception.

By following the simple tips below, you can enjoy FREE TV with your Antop Antenna:
– Re-scan the channels after each switching of the Smart Switch.
– Scan channels monthly to find all available channels including newly added or changed.
– Do not place or hide the antenna in/behind any metallic objects.
– Install the antenna as high as possible and near a window for better reception.
– Keep the antenna away from any high-power consumption devices to avoid interference.

NOTE: Antenna effectiveness is influenced by the distance from signal origination point, station signal strength level, building construction, antenna positioning, reflections from nearby structures and any power consumption sources. The amount of free over-the-air channels you can receive will vary by area and antenna selection, check signal availability at Antop Signalmaps.

    I was really pleased, easy to install, ran scan for channels, the aerial found 80+ channels of which were HD. Brilliant picture, I would thoroughly recommend, saved a lot of unnecessary expenditure.
