Condition: Used
This Fiplex TC 25-4B1 VHF Transmitter Combiner system has been inspected and is in good used condition. It was pulled from a working environment where it was actively in use. The cabinet and cavity columns show normal wear consistent with field installation — some light surface scuffing and minor marks on the enclosure. All four Fiplex LTB 12B2 Dual Junction Isolator modules, the ARS 02-CMO-TXCM-101 transmitter combiners, and the ARS 821-171-01 cavity filters are present and appear intact. SMA semi-rigid coax interconnects are in place. Please review our photos and contact us if you have any questions.
