ABSTRACT:
A dual-frequency conformal multi-filiar helical antenna system (20) provides a low-profile, low drag antenna useable in flying equipment. This antenna system (20) securely holds within its shell (22) signal distribution circuitry (64), signal combining circuitry (68), and any other circuit components necessary for antenna system (20) to communicate with other stations or devices. Antenna system (20) has radiating conductors (24, 32) tuned to two different frequencies such that simultaneous transmission and reception of signals is possible in the same and opposite directions.
