Ground Loop Eliminator prevents audio hums and visual bars.

info@productnews.com (ThomasNet News) — Tue, 29 May 2007 08:08:47 -0500

Compatible with HD and Digital Cable, RGPC Eliminator safely removes Ground Loops from coax line that would cause scroll bars in video and constant 50/60 Hz hum in audio. It does not attenuate higher frequencies, ensuring interruption-free delivery of Digital and HD signals. When combined with TV Guard coax surge protector, products protect sensitive AV gear from catastrophic surges and maintain connection to Ground while eliminating loops.

Bandpass Filter suits multifeed applications.

info@productnews.com (ThomasNet News) — Fri, 18 Jul 2003 07:37:07 -0500

Model 13961 low-profile, waveguide bandpass filter is installed between LNA or LNB and feedhorn to suppress strong out-of-band terrestrial interference. Since unit does filtering at C-band frequencies, LNA and LNB overload is prevented and overall picture quality is improved. Filter is fully compatible with digital systems, providing low differential group delay characteristics typically less than 8 nanoseconds.
