GPS LNA+antenna stability measure

GPS LNA+antenna stability measure

(OP)
Hello,

I have a question. I have to measure the stability of a GPS LNA + antenna set from a supplier. I have measured stability without the antenna, only for the LNA, from DC to 8GHz. It turns that it is not stable from DC to 800MHz. Do you know in what frequency range GPS stability is usually measured? and what is expected?

Thanks,
