There are three versions of Antenna Magus downloadable through our website: a professional, an evaluation and a classroom version. Antenna Magus Professional is the full version of Antenna Magus. For the installation of this version, a licence key is required. This version is not intended for evaluation. A time and model limited evaluation version of Antenna Magus can be found here. A free, but limited version that can be used in a classroom environment, can be found here.

Licensing and Maintenance & Support

Magus offers node locked and floating (or LAN) licences. M&S is 20% of the official list price and allows access to latest updates, upgrades and technical support. A special discount will be offered when purchasing additional node-locked or floating licences.

Antenna Magus supports Windows Server 2003, Windows Server 2012, Windows Vista, Windows 7, Windows 8 and Windows 10 operating systems.

Antenna Magus licences are updated automatically. New licences are automatically retrieved over the internet. Thus the user never has to worry about licence expiry as long as the licence M&S is up to date.

Floating (Local area network) licences available

Multiple seat floating (or network) licences are available in Antenna Magus.

The floating licence option is the perfect solution for a medium size to large enterprise, or for the single user that requires flexibility. It allows users connected to a local area network to check out a licence and use Antenna Magus on their local machine. Floating licences can also be used to run Antenna Magus through a remote desktop connection.


If you have already purchased a node-locked licence with paid M&S, the licence can easily be upgraded to a floating licence at a reduced cost.

Download floating (LAN) licence manager

This floating licence manager application is required to administrate floating licences on an Antenna Magus floating licence network. If you have purchased a floating (LAN) licence, please notify your IT systems administrator to download and install this floating licence platform on your local licence server. If the licence server has a connection to the internet, the floating licence manager can be set to update the licence automatically. In the event of no internet access, a licence file is required.
