HF/VHF sectional vehicle whip, low profile, monopole, 4.2 m, 2-60 MHz


The APX41-LP is constructed for land mobile services in the HF/VHF Band 1.5 to 60 MHz.  It consists of three whip sections and a base.  The base is equipped with a heavy duty spring coil to absorb shocks and to allow for a semi-permanent deflection of the antenna when moving the vehicle.  To give better performance on lower frequencies, it is possible to add up to three more sections.  On higher VHF frequencies one section can be removed to give a better radiation pattern.
