The Beverage Antenna, 100 Years Later
www.arrl.orgTransmission Line The Beverage antenna has a characteristic impedance and not a feed-point impedance. Like a dipole antenna, current in the Beverage’s horizontal wire creates an electrical reflection or image on the ground below it. The current in the wire and its image create an unbalanced transmission line with a characteristic impedance ...
GUIDELINES FOR USE OF UNDER GROUND CABLE SYSTEM …
cea.nic.inhigher current carrying conductors (AL-59, HLTS etc) may be used in sub –transmission and Distribution system. Since, the insulations between the conductors is provided by air, overhead power lines are generally the lowest-cost method of power transmission for large quantities of electric energy from one point to another.
