This paper proposes the use of motorized lift tower as the support,carrying light conductive cable as the medium-wave antenna transmitter,which solves the problem that the traditional medium-wave single tower antenna is difficult to achieve mobility due to the constraints of height,weight and insulation to ground.The motorized antenna can be transported by trailer,which is convenient to erect,and can realize high power and high efficiency local coverage or skywave coverage,which is an innovative technology for medium wave antenna to solve the problem of mobility and high efficiency,and has certain promotion and application value in the field of medium wave emergency broadcasting.
