Shunt fed tower
WebAnother broadcast antenna that had a grounded base is the shunt-fed (or slant-wire) antenna. This antenna comprises a grounded tower with a feed-line wire attached at a point of approximate transmission-line match. A series capacitor tunes out the inductive reactance of this feed-line. http://www.k5dkz.com/shunt1.html
