4.3.3.1 Front End Preselector
Each VHF and UHF MASTR V receiver is equipped with an external RF Front End Preselector, model
EA-555018-xxx. The preselector (refer to Figure 4-7) for each receiver module is mounted to a frame
assembly located on the rear rack rails near each MASTR V shelf. The preselectors provide narrow
bandpass filtering to meet the channel spacing typically used in the VHF and UHF bands.
