Cavity Tee Pass technology is employed in both VHF & UHF combiners which can be used for Tx and Rx combining. In most cases receive multicouplers and preselect filters can be used on the Rx side. Our staff can assist with system design as closely spaced channels can be problematic. The system design should consider insertion loss and isolation issues. Each Tee Pass cavity filter must have a dual isolator connected between the transmitter and the Tee Pass filter.
