Through Hole (Vertically Mounted) SMA Connector on PCB - Feasible for GNSS Application?
I haven't been able to find any edge-mounted connectors that go to a right angle vertically.


If this is a one-off hobby project, you can probably use one that looks like this:



Typically a 0.062" thick PCB will just fit between the center pin and one pair of ground stakes, allowing you to use this as a clunky edge-mount connector.

Or you can use a right angle adapter with whatever edge-mount connector you like.


  since it is TH, it will be soldered on the bottom, so there is a possibility of shorting the signal pin to the grounded housing of the connector


We (EEs in general) solder through hole parts with 0.050" spacing all the time with no trouble. The spacing between the body legs and the center pin on an SMA connector is typically more than twice this distance (it's about 0.14" on your part).


  Loss due to the right angle bend where the signal pin meets the plated through-hole. 


At 2 GHz this will not be a big effect.


  The leftover stub of signal pin sticking out of the bottom.


This is a real concern when using SMA connectors near their frequency limits (maybe 10 GHz and up). Ideally, you'd mount the SMA connector on the opposite side of the board from where the trace is to eliminate the stub.

At 2 GHz, it's not likely to be a problem even if you have the connector on the same side as the trace.

If you're paranoid, you can get connectors with through hole ground stakes for mechanical stability, but surface-mounted center conductor like this:



But these connectors probably need to be reflow soldered rather than hand-soldered.
