Racal Antennas Limited has many years of experience in design, development and manufacture of manpack/portable antennas for the military user. They have been developed after consultation with military users and radio manufacturers worldwide.

The 3504 series wideband tape antenna has been designed for manpack radio applications, with suitable radio antenna tuner unit, operating in the 100-400MHz frequency band.  This type of antenna is more suited for combat conditions where physical restriction on the user and radio is not desirable.  The 3504 antenna is constructed from a number of stainless steel tape elements, sheathed in a protected durable sleeving.  The tape antenna is supplied with an antenna matching unit (AMU) optimised over the full operating band.  The radio interface end of the AMU can be tailored to the radio manufacturers bulkhead interface.
