• G5RV Beam  ^pop - G5RV 40m Beam Antenna. Adding a 28 ft. piece of vertical wire to one end of a 102 ft. center-fed dipole turns it into a 40m beam with a very wide beamwidth

• 40m loaded dipole - This 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.
