HF sectional vehicle whip, monopole, 4.2 m, 2-30 MHz


NSN: 5985-25-126-6707

The APX41 is constructed for land mobile services in the HF-band 1.6-30 MHz.  It consists of three whip sections and a base assembly.  The base section is equipped with heavy duty spring coil to absorb shocks and to allow for a semi-permanent deflection of the antenna when the vehicle is on-the-move.  To give better performance at lower frequencies while static, it is possible to add up to three more sections.
