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.

Excellent performance for short to medium distance HF communications. Available in a range of lengths to suit installation requirements.

Supplied completely assembled and ready for installation. A range of coaxial cable lengths and types, and mast options are available but are ordered separately.

Up to 1000 W RF power rating. Separate variations are available to support power levels of 125 or 1000 W.
