These three aerials are for the Hermes system; a fourth whip-aerial type is missing.
The given dimensions are for the largest type (the folded tetrapod aerial with the hook) opened out, so the four arms point to the corners of a tetrahedron. This aerial is used with the range-extending Relay Unit and can be hung from a tree branch to maximise range.
The thin whip aerial is 480mm long and its base is 23mm diameter, weighing 40g.
The short helical aerial is 185mm long, and 15mm x 48mm at its base, weighing 65g.
All aerials use TNC connectors (TNC = Threaded Neill–Concelman, named after its two designers; BNC is the bayonet version).
