First the good news: The seller ("lets-sell") has quickly and efficiently delivered replacement because of Mantelstromfilter was broken (connector pulled out when releasing the connection). Now the bad news: The Mantelstromfilter not working. The signal strength drops to zero. Because the part is completely unusable I dissected it and looked at the inner workings of detail. Overall, four capacitors are in the circuit. One connects the outer conductor, two further connecting the inner conductor. Unless so it should work, if there was not yet a fourth capacitor: A 10 nF capacitor is connected between the inner conductor and shield. In the typical UHF frequencies provides this capacitor represents a short circuit. No wonder that the signal collapses. Something incomprehensible for me the positive reviews, may have different Mantelstromfilter be sold?
