[QUOTE="jeallen01, post: 1136812, member: 176704"] I was "working from long-ago memory" and so you are correct regarding "10Base 2", but - having looked at the document that s-band linked, - that definitely mentions 75 Ohm cables in one (probably several) places and so I think the 50-75-50 ohm impedance changes look to have been taken into account. On another point, I suspect that that document may have been drawn up in N.America and thus I now wonder if any companies [I](apart from EMP- Centauri obviously!) [/I] on this side of the Pond ever took the system up and whether MoCA products are [I]currently [/I]available "over here"? Edited: just tried to look up the EMP switch illustrated by [USER=180189]@EnoSat[/USER], and that threw up [URL='https://emp-centauri.cz/product-category/common-wiring-for-data-and-television/']this page[/URL] on their website - so it does look like kit is still available but at least some of it looks to be limited to 100 Mb/s and not up to 1 Gb/s [/QUOTE]
