When amplifying weak digital signals, amplifier noise figure (N/F) is critical. The noise of the amplifier will be added to the noise of the incoming weak signal. The lower the amplifier Noise Figure, the weaker the digital signal that can be reliably amplified. So these very low noise amplifiers will work where others fail. Vision designed these amplifiers using the latest semiconductors and SMD technology for industry leading low noise figures and reliability.

Avoiding 4G-800 LTE interference when using a masthead amplifier:

1: Choose the right model for your local transmitter

2: For channels 21-56 use only V20-1356 or V20-2756, The extra filtering above channel 56 will reduce 4G-800 signal levels to a manageable level. Use the minimum gain required for stable reception.

3: Where a TV transmitter uses a range channels up to Ch60 in close proximity to the 4G800 transmission frequencies, we recommend using a high energy amplifier. This allows weak channels to be amplified before filtering the 4G-800LTE. The high energy capability will cope with high levels of 4G-800 LTE without overload.
