High-pass Filter
The High Pass Filter (HP) 4-53 MHz (Part number: FILTROHP4-53ALT) , and is available on the Twoosk Marketplace.
The ALT-HPF-6KV-54 high-pass filters attenuate input noise in the sub-band section of the cable spectrum to optimize return services. This filter can also be used to eliminate or restrict user access to the sub-band's return frequency, for example, allowing only the TV signal to pass and filtering out the internet signal.
