![]() This not only keeps your MoCA signals from getting out to your neighbors' houses, it also helps reflect your MoCA signals back into your home coax, which helps keep the MoCA signals strong even when they have to traverse multiple splitters.Īlso note that there really is no substitute for installing real Ethernet cables in your walls. +- | Coax (MoCA) port Ethernet port | -+Īlso note that when using MoCA you should always put a "MoCA filter" (they're cheap small passive devices) on the coax line coming into your house, before it hits the first coax splitter in your home. +-+Ĭoax feed from CATV/DOCSIS operator - Coax Splitter - | Coax (DOCSIS WAN) port Ethernet LAN port | -+ Then, yes, elsewhere in your house you'd connect another MoCA adapter to a different coax CATV outlet, and connect its Ethernet port to…whatever you want connected to your home Ethernet LAN, like another Wi-Fi AP, or a PC, or whatever. Then you'd connect an Ethernet cable from a LAN port of your home gateway router, and connect it to the Ethernet port of your MoCA adapter. In general, you'd put a coax splitter in front of your DOCSIS modem, and run a coax cable from the splitter to the MoCA adapter. I have several HDHomerun OTA tuner boxes.MoCA uses frequencies far above the frequencies used by Cable TV / DOCSIS operators, in order to send home LAN networking signals over the same home coax as your CATV/DOCSIS service. I could move Moca back to the “cable” coax runs. I am also going to run two new cat6 cables which will allow me to eliminate one of the Moca adapters. I noticed the two filters and wondered if the Moca filter is actually needed. I recently added a coax run so now each location has both Spectrum cable and antenna. I don’t have any RF test equip other than the BT-1000. I also have a Winegard BT-1000 amp the I can swap with the LNA-100 to check the signals on each channel. ![]() At a later date I added the LTE filter and left the Moca filter in place. I added the Moca filter between “main” two-way splitter and I only had 1 coax to one of the three Moca locations so I moved moca to the OTA coax. I currently have both Spectrum cable (through the home owners association) and antenna (in my attic). The Main and second spitter are Moca rated – most of the other splitter are only 1GHz. Some of the outputs aren’t actually needed and have terminating resistors. The “TV” out of each Moca adapter is split 8 ways (a two-way splitter feeding 2 four-way splitters) total -17.5 to the amp (-3.5 -3.5 -3.5 -7). The other two Moca adapters connect to second splitter -7.0 total to the amp (ignoring cable loss) ![]() The second two way splitter connects to the other leg of the main splitter. One moca adapter connects to the “main” two way splitter connected to the amp -3.5 dB to the amp. Also, it only shows the “Moca” coax segments. You can also look at using a HDHomerun tuner box directly after the first splitter, assuming the amp is 15dB amplification. i assume you are using the TV out from the moca modem rather than going through an additional splitter.Ĭan you provide a full layout of the cabling paths with all devices identified by model # What are the dB loss ratings for the two splitters ( presumably going to TV). it is easy to insert another splitter (capped unused port) if you need to drop the signal level on the shorter path.Īre you having TV tuner signal level issues at the TVs ? You have to check the signal level at the tv tuner for each channel to verify. Note: it is also possible to cause tv tuner problems with too much amplification. You can look at the diagnostics pages on the modems and see if you have higher than expected errors or lower bit rate sync between the modems. i use a channelmaster pre-amp 7778 or 7777 and have not needed the moca poe filter, but i run a physical star of moca coax runs rather than a branched layout like you show. Would need to understand the reverse direction signal attenuation on the AMP outputs to comment more. If you have >20dB amp budget then should not be an issue. i included 3.5 dB connection/internal splitter loss in case. i forget if the moca adapter TV bypass is zero loss or not. Should be no more than 3.5+3.5+3.5 +3.5 +3.5 = 17.5dB to a TV off of the last moca modem if i counted right. With the amp, the moca filter will not make a difference for line loss, unless you have only 15dB of budget and more than 3.5 dB insertion loss at each splitter.
