900 MHz Helical Antenna
I decided to build a pair of helical antennas, one for each circular sense. Helical antennas have broad bandwidth
A 3 element beam Band six meter
Spacing between elements is 34 and 1/2 inches. The elements are 1/2 inch aluminum tubing of 1/16-inch wall thickness
A 144 MHz Pocket antenna
A dipole fed in his center by a coaxial line. This layout is simple and efficient although the adaptation is not perfect, 50 ohms
