I'm back with more questions and some answers. To recap, we have an HD antenna, a fairly new TA-52 distribution amp, a bank of 45-year-old splitters, and RG59U cabling running to twin-lead wall-plates in the units. It looks like our building antenna distribution system is in fact wired in vertical tiers, and that our splitters are doing badly with the higher UHF broadcast frequencies (bypassed the splitters to test that).
I'd like to replace them with new ones, and am asking if those found on the Monoprice site would be ok, and if not, what would be recommended?
I'd need to replace a 2-way, a 3-way, and two 4-way splitters, from which the drops to the tiers emanate.(I've made some progress mapping the drops, with more to go.) Thanks
