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 690 series 2.7 metre whip antenna has been designed for manpack radio applications, with suitable radio antenna tuner unit, operating in the HF and VHF frequency bands. The whip sections are manufactured from copper plated steel tube sections.  Each tube section is joined together by shock cord or elastic bungee with a combination of springs and ferrules.  When the bottom section is held in the hand and the remaining sections are dropped the antenna will simply snap together ready for use.

The folding whip antenna is used in conjunction with a flexible assembly (commonly known as a gooseneck).  The radio interface end of the AMU can be tailored to the radio manufacturers bulkhead interface.
