Generally, in RF signal chains, adding test points is a bad idea as it would cause an impedance mistmatch, thus degrading the circuit performance. Additionally, adding any sort of stub in a circuit path will resonate as some frequency causing EMI issues, frequency peaking at some point along the frequency domain among other problems. In short it is just a bad idea.
Further, adding the scope probe into the signal path will cause loading issues. Typically if you want to break into a signal chain, you would cobble some sort of pigtail into the chain just for test, then return the circuit back to its normal configuration when done.
One method of sampling off a port would be to use something like a RF coupler (also would add loss in chain), thus maintaining an impedance match. Even in this case SMA connector or similar would be the interface of choice.
I am not sure how you would be using these connectors, but at the frequencies you have mentioned, I would say your wasting your time to mass produce as most designers would not use them for UHF applications.
