You could try sweeping a harmonic from a signal generator across the antenna passband, this would be visible on the spectrum analyzer and might give you an idea if the preamp is amplifying or attenuating the signal. Try it with the preamp power on and off. If your signal generator does not generate sufficient harmonics at L band you can feed the signal into an overdriven MMIC amplifier.
