Part of the guidance processor (3) is combined with the VHF radio device, coupled via an antenna coupler (13) with a VHF antenna (14), for providing a VHF data transmission path (1). The remaining part of the guidance processor combined with a cryptographic unit (7) and the HF radio device, coupled via an antenna matching stage (10) to a HF antenna (11), for providing a HF data transmission path (2).",
