Antec does not exits anymore the new company is now called ARRIS. One of the problem with the ANTEC NODE and RF amplifier, was a 30 dB high impedance test point, which has now been replaced by a 20 dB dir. test point. Their new NODE and amplifier seems to be well built. They have a super web site http://www.arris.com
Good luck
