Unlike the coaxial F adapter acclimated today for the aforementioned purpose in North America, the IEC 60169-2 adapter is not akin to the 75-ohm appropriate impedance of the antenna cable used, its impedance is about 50-ohm. The abridgement of impedance analogous causes arresting reflections in the cable, arch to apparent arresting baloney on VHF and UHF frequencies (but not MW or Shortwave).
The IEC-169-2 adapter is recognised as a antecedent of arresting baloney and has become a accurate affair with agenda arresting reception, accurately UHF HDTV.
DAB (digital radio) and added accession modes are not as acutely afflicted by the impedance analogous issue, so alone HDTV and digital accession systems are encouraged to use the F connector.
In animosity of getting somewhat clashing for avant-garde alternation VHF and UHF TV frequencies, due to automated inertia, the Belling Lee adapter is still acclimated today as a TV arresting accession connector.
In Europe and the Americas this adapter is not acclimated to affix digital TV antennas. The added electrically acceptable 75-ohm F adapter is standard. However, the anachronistic BSB receiver acclimated a Belling Lee adapter for the LNB feed
