Jeff,
Adding the upgrade should have negligible (if any) effect on the C2's UHF reception. If your reception has been significantly affected, that suggests to me that either the diplexer is bad or one of the short coax cables is defective.
I will look up your order and will pull an upgrade kit from inventory, test it, and ship it out today as a replacement. Please let me know if this resolves your reception issues.
Steve
