Product Announcement from North Hills Signal Processing Corp.
DTV Humstopper (50 MHz – 900 MHz)
Is your TV signal noisy? North Hills has developed the NH16573, a high quality ground isolation transformer with a bandwidth from 50MHz to 900MHz. This "Humstopper" can be used to eliminate the 60Hz hum bars and ac beat interference from your broadcast and cable TV that is degrading your picture.
The NH16573 is the solution for passing any UHF/VHFbased signals, including Digital Television ("DTV"), without degradation, while eliminating the ground loop interference. It has built-in DC isolation between its input and output RG-59 "F" connectors.
North Hills' "Humstoppers" provide quick, cost-effective solutions to interference due to differences in ground potential or induced common-mode noise.
