ALYX ANTENNA GUIDE
INVERTED L ANTENNA FOR SHORTWAVE RADIO BROADCASTING


GENERAL DESCRIPTION


photo inverted L antenna The inverted L antenna is simple and easy to construct.

The azimuthal radiation pattern is slightly asymmetrical with about 1 to 2 dB increase in the direction opposite to the horizontal wire.

The inverted L antenna requires a good buried ground system or elevated radials.

The antenna is a form of top-loaded vertical, where the top loading is asymmetrical. This results in both vertical and horizontal polarization.
