Product details
The CPI LRL1 is a 1:1 redundant LNA system from CPI's LRL-1000 Series for L-Band earth stations. It protects one receive chain: an online LNA and a hot spare share an outdoor switch plate at the antenna hub, and the indoor controller switches to the spare automatically if the online LNA fails.
The plate carries CPI LL-1500 Series LNAs (35, 40 or 45 K), with options for -30 dB input couplers, -20 dB output couplers and an offline I/O port. The 1RU controller has dual power supplies and SNMP over Ethernet.
Order it as LRL1XXX-XXXXXXX; Digisat completes the order code from your band, LNA and option choices. The LRL-1000 Series comes in 2 listed models; compare them on the series page.
