The thickness of this coaxial, which is its USP, also becomes its downside. 19. I logged into my CM1100 modem and it says that the Downstream Bonded Channel (Partial Service) - only channels locked are 1 - 20 (out of 32), and the rest of the channels are unlocked at 0 values. Eliminate monthly rental fees; Channel bonding of up to 16 downstream channels and 4 upstream channels provide data rates up to 680 Mbps for downstream, and 143 Mbps for upstream To reduce the losses from the skin affect, a larger diameter coaxial cable can be used but increasing the coaxial cables dimensions will reduce the maximum frequency the coaxial cable can transmit. Hence, a coaxial cable cutoff frequency could be where the coaxial cable remains within specification, or within a reasonable margin to avoid transverse-magnetic (TM) or transverse-electric (TE) propagation modes. If the modem IS using frequencies above 1002 MHz, precluding use of a protective MoCA filter on the modem's coax input port, you may need Cox to wire a dedicated coax line for the modem -- though one other alternative may be to try manually configuring a MoCA channel above the DOCSIS 3.1 range. "Since the television signals are vestigial sideband modulated, if the beat products can be manipulated to fall on or near the RF carriers themselves, they are much less offensive..", --from William Grant, Cable Television, 2nd edition, GWG Associates, Schoharie, NY, 1988, page 82.
