Airborne and subterranean UHF antenna

A ruggedized ultra high radio frequency antenna disposable at the rear of a hardened target penetrator warhead is provided. The antenna is usable for communicating signals from a transmitter in a deployed target penetrator warhead to a local repeater where retransmission to a more remote location can occur. The antenna includes a length-shortening and penetration abuse-resistant dielectric embedding material also supporting the subterranean signal communication to the local repeater function. Antenna radiating element fabrication from porous material such as screen wire and use of the dielectric material in a manner providing large G force tolerance and external dielectric variations are included.
