[Repeater-Builder] Modification of Sinclair Q2220E 144Mhz duplexer to 220Mhz

I have recently aquired a functional high-split (148-174) Sinclair Q2220E. Since it does not have enough isolation for my 100W VHF repeater, and I already have a good working Q202 on there now, I am planning to convert this over to a Q2221E for 220Mhz. I am pretty aware of how duplexers work
