This is very nasty. At approx. 40 metres distance a 'temporary GSM/UMTS contrapsion' fills our angle towards 110 degrees, i.e. DL and OK. This weekend we learned that also a 70cm repeater is mounted in this tower (???!!!). Now we understand the sometimes spontaneous blocking of our receivers. Anyway, if somebody can help us repositioning this tower, please let us know!!   (7/44)
