Mantis Series
Our Biggest Bad Boy 40 Meter Antennas!
CUBEX 40TH ANNIVERSARY QUADS!
The Mantis-series cubical quads achieve exceptional performance on the 30-meter and 40-meter bands. These distinctive antennas are the result of decades of quad design and manufacturing experience, celebrating 40 years of innovation in 1997.
The biggest and baddest quad in our catalog, this antenna requires a lot of space, a serious support structure and a high-torque rotator.
Don’t underestimate the scope of this type of project, however we make it as easy as possible with our complete kit of high-quality materials.
Go with “the choice of DX Kings”… go with Cubex Quads!
Due to size limitations, ALL Mantis Quads ship via Ground Freight
