Roof antenna for AM/FM receiver

[Prbrianpr]

Hi everybody. I'm new here and have a question. Maybe have an easy answer but I searched by 3 days the internet and only get mixed answers. My home is a concrete house with rebars also have wifi mesh Smart switches etc... The thing is all indoor antenna works very poorly. I thought that just getting an coax cable from the receiver to the roof and put antenna in the roof far from interference is a good idea. The problem started when I want AM and FM. I have AM loop connection and FM 75ohm connector on the receiver. I also found a FM/AM splitter from one coax cable. And F to leads adapter with the name matching transformer. Ok. But there's no are home AM/FM roof antenna. There are FM home antenna and AM/FM for vehicles. Also the distance from roof to receiver will be like 75 to 100 ft. I want my receiver working with all AM/FM CD, Tape, record and digital streaming media.
