    A couple of weeks ago I made a broadband magnetic frame. This antenna is very interesting to me and I took some videos about it. On her very strongly affect domestic interference, try to place it as far away from the house perimeter. The best option-roof.
    Antenna Options: 5 turns, an internal diameter of 200mm of cable RK-75 (You can use either coaxial).
    the central core with the two ends of the amplifier inputs, braid one side only minus circuit, on the other hand is in the air.
