Talk:Communication Systems/Antennas

In particular the "folded dipole", a recent interest of mine, shows a line with a 1/2 on one side and a 1/2 on another side of the top half of this picture. This is wrong. The top half is 1/2 wave length, and the bottom half is 1/2 wave length. for a total of 1 wavelength (or lambda).

No impedance formula, or typical impedance number is given for any antenna. A typical Z value for a folded dipole is 300 ohms.

There is no mention of J-pole, Slim jim or cubical antennas are in this section.

No link to phasing harness calculations, though you mention the topic in passing.
