The COL7 is a lightweight collinear design with minimal wind loading, making it ideal for mounting on moderate support structures. The radiating elements are constructed from alodined aluminium and are arranged as a series fed array. The internal elements are enclosed in a fibreglass radome which is fitted to a aluminium mounting tube. The COL11 is electrically identical to the COL7 antenna (although it does feature an up-rated stub design for additional power handling capabilities). The radome is coloured black to maximise solar heat retention and this has been shown to aid significantly in ice shedding. A large, 60mm diameter alodined aluminium mounting tube supports the radome.
