Although the discussion here often revolves around the "edge of the envelope", there are some things that might not need that level of detail. I have a similar problem, with a workshop in the basement and a GPS antenna on a balcony 3 stories up. I had a 15 metre length of RG213 running between those two places for a HF antenna which is no longer used. It already had UHF (PL-259) connectors on the end. I just made up a little adaptor for the GPS antenna lead using a cheap plastic box, a SO-239 socket and plenty of silicone sealant. It works perfectly although I know a TDR would have apoplexy looking into it. I use it for non-critical stuff and testing, my Z3815A had a dedicated antenna with a proper lead.
