DBS L-Band Transport  
SATCOM  
The Model 2990 PRO L-Band Satellite Transport System pro-  
vides an economical solution for transporting digital signals  
for numerous satellite distribution applications, including  
headend relocation, and distribution of digital broadcast sys-  
tems (DBS). The system utilizes a cost-effective coax cabling  
configuration to distribute the RF signals from the dish to  
the transmitter and from the receiver to the headend.  
The single-mode optical fiber between the 2990PRO transmitter and receiver  
allows transmission distances to 35 km at 1310 nm. Furthermore, using LNB  
power from the transmitter decreases the need for additional equipment at the  
dish site. RF alarm and indicator LEDs allow for a quick assessment of the link’s  
operational status. The Model 2990PRO L-Band Transport System, whether used  
in an antenna remoting application or
