Duplexers: Decibel Products

VHF / UHF DUPLEXER
BANDPASS REJECT DUPLEXER

Designed for duplex systems that operate with close frequency spacing, these duplexers consist of 8" (203.2 mm) diameter quar-terwave coaxial cavities. They are interconnected in a bandpass-band reject configuration using double shielded coaxial cable.


DB4060-WC-B. VHF Duplexer, 143-156MHz. Price: $3,359.00 Dls.

DB4060-WC-C. VHF Duplexer, 154-174MHz. Price: $3,359.00 Dls.






DB4076-Z-A. These duplexers use quarterwave coaxial resonators, interconnected in a bandpass-band reject configuration with double shielded teflon dielectric cable. They isolate the receiver from the transmitter and reduce Tx noise in most solid-state and tube antenna systems.
UHF Duplexer, 4 cavity, 450-470MHz. Price: $1,616.00 Dls.

DB4077B. UHF Duplexer 4 cavities in square sections modular type for rack 19", 470-512MHz 3 MHz of minimum separation, 1.5dB of lost of insertion and 175MHz of power. Price: $2.659,00
