Gawd. What an installation nightmare a 544 would be.
UNLESS, it only had RF outputs for TV2-4 - and they were all on the same port. In other words, a micro "head-end" to fed the whole house.
AND, it used a pair of DPP inputs - with the DPP Separator built-in. In other words, only 2 RG-6 feeds with no extra hardware. Of course, a DPP44 or DPP Twin would be required.
