411 Terminated Folded Dipole
The 411 terminated folded dipole antenna is a 2-wire antenna for broadband operation in fixed stations. This Codan antenna provides perfect performance for HF radio communications. The 411 antenna is supplied completely assembled and ready for installation. Additionally, The 411 antennae can be mounted horizontally between two support systems, or as an inverted “V” using a single central support mast.
Description
The model of 411 Antenna should be selected to suit the application depending on the required power rating and the maximum amount of available space to install it. As a general rule, the radiation efficiency of the 411 Antenna increases with antenna length so it is recommended to select the longest variant that the installation site can accomodate.
The 411 Antenna can be mounted horizontally between two support systems, or as an inverted “V” using a single central support mast. To optimise the antenna for Near Vertical Incidence Skywave (NVIS) communication, use an inverted V configuration or adjust the installed height above ground.
The 411 Antenna is designed and manufactured with corrosion and UV resistant materials to withstand a wide range of environments.
