Channel Combiner for LPTV
The filter requires a minimum guardband of at least one channel. Channel "through loss" is typically 0.5 dB. Each assembly consists on two, three, or four bandpass filters with individual inputs and a common output.
Connectors are 50-ohm 7/8th. Individual channel bandpass filters are 3 × 12 × 17-inches and weigh fifteen pounds each. They are constructed of welded aluminum. The filters are mounted on a common panel for studio installation.
