At 30 MHz, this 1.5pF capacitance represents a reactance of 3.5K Ohm.
This rather sweeps aside your specification for the load and replaces
it with 4700 -j3537 Ohms.

Actually 1700 -j2258 Ohms

As you can see, this is the reason why open stubs are avoided.
"Knowing" the parasitic capacitance is problematic. The fringing
effect at the end is difficult to manage whereas a short is much
simpler to define and implement.
