PRODUCT OVERVIEW

The DBD2 is a dual band diplexer that enables simultaneous VHF and UHF operation, either

with a dual-band transceiver and separate VHF and UHF antennas, or with a broadband

antenna and two transceivers (one for VHF and one for UHF).

Rugged Construction: This coupler is designed to handle 150 watts when connected to the

correct ports. All 1000-volt capacitors have been used in filter stages to ensure trouble free

high power operation.

Weatherproof: The black anodized aluminum housing is designed to provide splashproof

protection when installed in a vehicle during operation. Teflon “N” connector terminations

ensure highest quality interface for all signals.

Isolation: A minimum of 20dB isolation at VHF and UHF in active bands with VSWR @ less

than 1.5:1 with all ports terminated at 50 ohms.
