Note:
Above cable length value is offered based on RG6 (75-5) cable transmission.
Professional ones can calculate the transmission length for different material
cables by referring to appendix 1 and 2.
For example, from appendix 1, it shows channel 5 receive sensitivity is -80dBm.
From appendix 2, it shows 700 meters RG6 cable signal loss value is -61.91
dBm at 211Mhz. This value is less than -80dBm and it is within the required
