ALYX ANTENNA GUIDE
SLOPING V ANTENNA FOR SHORTWAVE RADIO BROADCASTING


GENERAL DESCRIPTION


photo sloping V antenna The sloping V antenna is designed for medium range skywave circuits.

The antenna is directional and intended for use in the 8 to 30 MHz frequency band. Operation is extended down to 2 MHz with reduced performance.

The antenna is horizontally polarized for efficient performance over all types of soil and will handle up to 10 kW of power.

The antenna requires a minimum time and cost for installation and features low-maintenance components. Only a single support mast is required.

The sloping V antenna is fed with a balun that is usually located at the top of the mast in case of a coaxial transmission line or through an open wire feeder line.

The terminating resistors should be in the order of 300 ohm.
