180 Family 490 Family CU-2275(V)1/490A-1 Coupler, antenna (cap/probe). Microprocessor controlled, pressurized for high altitude operations. TSO approved. 622-4731-001 *CU-2275(V)1/490A-1 Coupler, antenna (cap/probe). Same as -001 except has "bird cage" output RF connector. TSO approved. 622-4731-002 *CU-2275(V)2/490A-2 Coupler, antenna (long-wire). TSO approved. 622-6129-001 CU-2275(V)3 Coupler, antenna (C-5 shunt). 622-6841-001 CU-2275(V)4 Coupler, probe for use with the F-1602. Same tuning capability as the CU-2275(V)l. 622-7830-001 CU-2275(V)5 Coupler, wire for use with the F-1602. Same tuning capability as the CU-2275(V)2. 622-7831-001 490R Group for high speed aircraft, 200 watts average, 630 watts peak, 2-30 MHz It is based on the 309C-4 coupler control system. Used on shunt or notch fed antenna designs 490R-1 for the RF-101 490R-3 for the F-111 490R-4A for the Mirage 4 aircraft CU-2314(V)1/490R-2 Coupler, digital shunt antenna (F-111) 622-6897-002 CU-2314(V)2 Coupler, digital shunt antenna (F-15/16) 622-7094-002 CU-2314(V)3 Coupler, digital shunt antenna (B-lB) 652-0972-002 CU-2314(V)4/490S-4 Coupler, digital dual shunt. TSO approved (KC-10, C-130, G-III, G-IV) 622-7375-002 490A-5 Coupler, antenna, is an improved tuning range version of the CU-2275(V)2 coupler. The enhanced capabilities include extending the long-wire antenna tuning limit for antennas whose lengths range from 20 to 100 feet (dependent on the aircraft) and extending the capability of tuning a whip as short as 5 meters (16 feet). TSO approved. AC or DC power. 622-9741-001 490S-4A Same as 490S-4 plus receive through tuned circuits (MH-53J/M) 822-0648-001 490X-1 antenna coupler and 309H-1 antenna coupler controller (used in the AN/TSC-60)
