Design
The multicoupler is housed in a 19” subrack with very
good RF shielding and consists of the following subassemblies:
- RF amplifier
- power divider boards 4-way
- processor board
- redundant LAN interface for control and monitoring
- redundant power supply unit
- switchable DC bias tees with overload protection
Specifications subject to change without notice, 2013-08-27, dble_gta2214.docx
All the necessary signal, power supply and earthing
connections are provided at the rear.
The mains switches are located on the front panel.
Special features
The unit is constructed using a modular approach
utilising 19" plug-in sub-assemblies which enable ease
of installation and maintenance.

L-Band Antenna Multicoupler Model GTA2214
Antenna multicouplers are used in modern receiving
stations and provide distribution of antenna signals to
several receivers without loss and deterioration of the
signal quality.
This antenna multicoupler consists of 16 divider
modules each with 1 input and 4 outputs in the
frequency range 950 … 2150 MHz.
