Rau kev saib xyuas ntawm lub kav hlau txais xov feeder system, lub hom phiaj yuav tsum yog nyob rau lub caij nplooj ntoos hlav tshuaj xyuas thiab lub caij nplooj zeeg tshuaj xyuas. Nws yog ib qho tsim nyog yuav tsum ua tib zoo xyuas thiab saib xyuas lub ntsiab feeder, rheostat, thiab feeder cable. Kev sib txuas thiab kev sib khi ntawm txhua feem ntawm lub taub hau feeder thiab jumper. Kev saib xyuas txhua hnub tuaj yeem soj ntsuam VSWR qhia ntawm lub ntsuas hluav taws xob tso zis ntawm TV transmitter (ib txwm yog S<1.1), the maintenance work on the tower, can start from the fixing of the main feed and feeder cables, the fixed jumper should use copper screws, and make the jumper and the feeder head in good contact, for the rheostat, carefully check the sealing of the connection parts and the feeder cable head, check every summer to prevent water ingress, and find the cause of the problem in time to deal with it.
