  • Notes
  • The model JK-66 has a Beam-A-Scope antenna built in. A "Beam-A-Scope" is just the own branding for an internal loop antenna, as for instance Zenith called "WaveMagnet". Often the loop is shielded with a wire cage or foil. Sometimes an external antenna coupler is built in. Can be either extra turns on the main coil or a smaller inductor nested within the larger coil. Some can be turned in direction, most can not. Some are very big, like on the model J-1005, others are small. They have to be right to fit the RF circuit.
