RANCANG BANGUN DIPLEKSER UNTUK PEMANCAR TELEVISI ULTRA HIGH FREQUENCY (UHF)

摘要: The development of television technology in Indonesia has growth rapidly. This fast is marked by the presence 10 private stations. Establishing a station requires lot expense especially to build transmitter and tower antenna. paper presents research design built diplexer system for merging two signals transmitted an antenna transmitter. conducted using copper pipes with diameter 3.2 cm 1.4 cm. use different sizes intended obtain impedance characteristic (ZO) equal 50 Ω . pipe designed form open close end transmission. There are mixing frequency tested, those 620 MHz ( at terminal A) 600 (at B). result shows that A acts as band pass filter around stop Terminal B MHz. Based on results obtained,  this can be applied merge transmitters carrier MHZ within single
