It's important to put a low-pass filter at the "Point Of Entry" (POE) where the CATV line comes into your home, before the first splitter. If you really need a CATV signal booster, you may be able to find a MoCA friendly one nowadays. So TV signal amplifiers on your in-home coax wiring can be a MoCA killer. less than 850MHz or 1GHz), and may filter out frequencies above that. TV signal boosters (amplifiers) often only amplify frequencies traditionally used by CATV channels (i.e. You could test it yourself if you were a EE or RF nerd with some lab equipment. If your splitters don't say a rating or say a rating that doesn't go up to 2GHz, that doesn't mean they don't pass those higher frequencies very well, it just means no one designed or tested them to do that, so you don't know. It is helpful to make sure your splitters are rated for 5MHz (or below) to 2GHz (or above). Coax cable attenuation ratings are often given in decibels per 100 feet. In general, CATV is expected to use frequencies from 5MHz up to 850 MHz or 1GHz, and MoCA is designed to use frequencies above that, up to 1.6GHz, and perhaps up to 2GHz in the future.ĭifferent cable designs can attenuate different frequencies to different degrees, so it would be helpful if you knew how much your coax cables attenuate the signal at frequencies between 1GHz and 2GHz. The MoCA specs allow for MoCA devices to use different frequency bands in order to avoid the frequency bands used by the CATV or satellite TV signals that might also be on the same coax in some homes. The fewer splitters your MoCA signals have to to go through, the better. In fact, RG-59 should be avoided because its attenuation is too high. In general, something like quad-shielded RG-6 is going to work better than RG-59. Topologically, it's expected to be a tree made by a single splitter or a small hierarchy of splitters. MoCA is designed to work over the 75Ω coaxial TV antenna / cable TV (henceforth "CATV") / satellite TV cable you already have in your home. Using speedtest-cli I get ~850 on ethernet. But when testing with the MoCA bridge, it caps around 150. Using iperf3, I can get ~950 mbps to any of my VMs when plugged into the switch. As for coax cables, the only one I can view right now says catv 18 AWG on it. OPNSense running in a Proxmox VM on a D元60 G7 (passthrough NIC with 2 gigabit ports)Īll ethernet connections are cat5 or cat6 cables plugged into gigabit ports.I believe there is only one splitter to this coax cable that splits from the point of entry into the home.The comcast modem is Model Number: TG3482G, CGM4140COM.I just used some coax cables I found lying around the house. My speed is capping out at around 150 mbps instead of 1 gbps. Plugged it into my OPNSense router and got it working just fine.īut one issue. I just picked up a pair of moca 2.0 bridges to serve wired in some rooms of my house.
