To all ,
I,m using an active antenna simular to Roelofs mini whip for over 10 years  ( circuit practically the same with DC coupling between the J310 and the 2N5109 ) with very good results . I tried it in combination with a lot of different receivers and came to the conclusion that any intermodulation was caused by overloading the receiver and not by overloading the active antenna . Easy to check by using an external or internal attenuator with steps of 10-20-30 dB  between the active antenna and the receiver .
However I do not  have any powerful transmitters in the neighbourhood .
