The Sirio M 400 Stardust is a quarter wave ground plane base station antenna for CB and the 10m band. It radiates omnidirectionally with a low radiation angle for DX work, and the aluminium alloy build gives it a high power handling capability. It suits base station operators who want a permanent mast mounted aerial that can be tuned by adjusting the whip lengths.
