After a year of trying several radio antennas I have finally found one which works for me. Have excellent FM reception and 5 AM stations with minor static noise. AM sports and news stations also foreign language stations.
Had no AM station reception before.
Bought an extension radio antenna cable and a radio antenna. Fed extension antenna cable under dash up A pillar and above passenger door. Fed antenna cable out of top B pillar along the edge of bunk bed behind tv and glued antenna to ceiling.
Best reception at that particular spot. Extra cable bundled up and placed behind plastic roofliner above passenger door.
