Codan’s 411 antenna is robust and reliable, designed to operate over the full HF band, and is rated for 150 W PEP at full duty cycle for voice and data.

The 411 antenna is supplied fully assembled, complete with anchor stakes, laminated installation instructions and canvas carry bag. No specialised tools are required for installation. The central antenna spreader bar is fitted with a sleeve that enables the antenna to be mounted into the Top section of a mast with an inner diameter of 32 mm. The antenna is constructed of Kevlar reinforced antenna wire for strength, long life, and immunity to kinking. The Codan 6 and 10 m Tactical Masts are recommended for use with this antenna.

The optimum height for general communications is 10 m. However, 6 m will improve Near Vertical Incidence Skywave (NVIS) radiation for communications over shorter distances
