We present, in this paper, pigtailed electro-optic sensors dedicated to the measurement of high power microwave signals in outdoors conditions. We give results on high power microwave single-shot pulses obtained with long fibre links (> 20 m) in hard environmental conditions (temperature variations up to 30°C). In these awkward outdoors conditions we obtain very stable measurements with rms signal fluctuations lower than 0.2 dB. We focus here especially on the design of the temperature-dependent-free system.
