Yes, I try combine the two signals by the same cable but if they (CatV and air) use the same frequency and some channels can lost, is necessary to use two lines then, If not theare another way.

Furthermore I wonder if this is really true or is another trick:

Model LPF-750 Low-Pass Filter

The Model LPF-750 Low-Pass Filter is used on systems when broadband entertainment feed
is supplied by a CATV service. The filter removes all CATV channels above the pass band,
allowing insertion of locally-generated ChannelPlus modulated channels.

Product Features

* 0 to 750 MHz bandpass frequency

* Passes off-air TV channels 2 to 60

* Passes CATV channels 2 to 116

* Allows insertion of TV channels 65 to 69

* Allows insertion of CATV channels 121 to 125

* Removes cable system noise which degrades the picture quality of the locally-generated channels



This is really serious, or is another story of you accept?
