Filters

Channel deletion filters are the key to success whenever adding a TV channel to an existing cable system. Regardless of whether you are re-inserting on an active channel or on a so-called "blank channel," it is generally necessary to use a filter to eliminate existing
video and/or "ground-floor noise."  Failure to use a filter usually will result in interference and/or grainy picture on the new channel.  Channel deletion filters allow the installer to add the new channel into any frequency slot of the clients choice.

Many installers prefer to use a low-pass filter instead of a channel deletion filter when re-inserting a channel onto a cable system.  This is due to the lower cost of the LPF.  In such situations, the re-inserted channel will need to go on the top side of the existing cable channels since the LPF will pass all channels from channel 2 through to the cutoff channel frequency.  A limited number of cutoff frequencies are mass-produced and usually offer adequate choices for most installs.  They offer the most economical filtering choices.  Should a custom cutoff frequency filter be required, please call our technical sales department for a quote.
 
Design assistance is available for any installation problem that you might run into...regardless whether it is for deleting a specific channel, eliminating a band of channels, using high or low bandpass filtering, removing an interferring carrier from another source, etc., we're here to assist.  Please don't hesitate to give us a call any time during our regular business hours.
