Viewsonics VSMA608C-10R 8-Port TV Signal Booster/Amplifier with Active Return Path (Retail Package with 5-Year Warranty)
The new VSMA-608C-10R amplifier is the best amp you can buy. It incorporates TWO complete amplifiers in one housing. The first amplifier boosts the forward path (50-1000 MHz) by a full 3.5dB. Each output port is +3.5dB higher than the input signal. The second amplifier inside the housing boosts the Return Path (5-42Mhz), so that you experience NO INSERTION LOSS. This is very important, because cable modems are very sensitive to loss on the Return Path. More importantly, Viewsonics uses a 2-chip design for the Return Path amplifier, so that it can handle the FULL POWER of a cable modem (up to 60 dBmV) and still maintain full compatibility with all cable modem signal specs (DOCSIS). Other manufacturers use only a single chip design which only handles up to 25dBmV, which is susceptible to failure when hit with the full power of a cable modem.
