Takeoff speed from high elevation airbases?

[Rifter]

I know that airports considered as high elevation airports are higher than 8.000 feet. But taking off with the F-4 from Tonopah (5.500 feet) seems already be to much elevation for the standard takeoff procedure. I get constant tail strikes there when sticking to the standard takeoff procedure which works well for me on sea level. I need reasonably more speed before beginning rotation (well beyond 80 knots) to safely get the F-4 in the air.

Are there any elevation related takeoff speed tables around?

Full aft stick doesn’t mean hold it there. You are the pilot. Only you can prevent tail strikes.

Sufficient aft stick should be applied prior to nose wheel liftoff speed to attain the desired pitch attitude. As the nose rises, pitch attitude must be controlled to maintain a 10° to 12° (first pitch mark) nose high attitude for aircraft fly-off. Caution must be exercised to preclude over-rotation due to excessive aft stick rate or an extended takeoff roll due to late lift-off. The basic takeoff attitude should be held during acceleration and transition to a clean configuration. Trim change and control action during this period are normal. The AUX AIR DOORS, WHEELS, and MASTER CAUTION lights may illuminate momentarily as the landing gear and flaps are retracted.

CAUTION: Rapid full aft movement of the stick between takeoff airspeed and 30 knots below takeoff airspeed may result in the stabilator hitting the runway with the possibility of stabilator actuator damage.

Of course I don’t hold it stubborn in aft position and wait for some magic auto takeoff to happen.   That would create tail strikes regardless of amount of lift forces in the F-4. I just realised that I have to raise rotation speed on high elevation fields and wanted to know whether there are takeoff speed tables depending on elevation.
By the way: Watching F-4 drivers on the servers reveals that around 75% of them create tail strikes at takeoff, regardless of field elevation. Happens easily with standard spring loaded flight stick.

Right now, F-4 players on public servers are a good example of how NOT to fly the jet.

Takeoff speed (IAS) doesn't vary by elevation, ground roll does. Nosewheel liftoff and Takeoff speed (IAS) vary by gross weight and Nosewheel liftoff is additionally affected by Center of Gravity.

Right. Only the needed true airspeed should raise with the elevation. Perhaps I unintentionally compared the different starts with different aircraft configurations (weight).
