Abstract

Explain the consistent medium-wave antenna. Orthodox medium-wave antenna is a vertical antenna for base isolation. The antenna cable is now passed to the Tower between two of NHK Kawaguchi stations 313 m drawn perpendicular to the first and th-2 broadcast. Tend to be circular tube column and truss beam-columns supported by the branch line in recent years. Antenna base ground is used to a relatively large station and a small transmitting station. In terms of matching consider from the antenna to the free space electromagnetic wave radiation.
