  • 40m loaded dipole

    Updated: 2021-03-22 03:42:20
    Antennas/40M/40 meter Dipole AntennasThis is an short dipole for 7 MHz. Total length of this dipole is just 10 meters, 33 feet. Missing lenght is balanced by a coil made of 49 turns of a 40mm diameter pvc pipe. The use of a choke balun is recommended, as always, to adapt the unbalanced coax cable to the balanced antenna, and to prevent RF feed back along the coax shield.

  • Improving Gain of the Super J-Pole Antenna

    Updated: 2021-03-22 03:42:19
    Antennas/J-PoleThe collinear J-Pole, often known as the Super-J, does improve the behavior over a regular J-Pole. there is an advantage when vertically combining 1/2 radiating sections to have a bit of separation between the half-wave end points. Get 0.8 dB more gain out of the trusty Super-J by replacing the traditional phasing stub with a long coil.
