If it is the pitot tube shown on the top of the vertical stabilizer, I
would be reluctant to use that location. Pitot tubes are normally
placed in a location that affords exposure to an undisturbed airstream,
and atop the vert. stab. just isn't that.

However, inside the plastic tip of the vert.stab is a likely location
for an antenna. The Lockheed T-33 used that location for the UHF . Of
course, replacing the coax was a bear -G.
