Aerial Photography - Modern
Designed
to be neatly slotted into the top of a scaffold tube, this array
has been inelegantly clamped to the side of a 1½inch TV
aerial mast. The top bit, the vertical rod, is a whip aerial with
a loading coil. The rest of the installation, the part that looks
like an aluminium representation of a dandelion seed, is a discone.
A discone gets its name because it looks like a disc mounted above
a cone, and it is a wideband aerial normally used for the reception
of radio amateur and emergency service transmissions. Quite how
the discone works I've never understood, but you can be sure of
one thing: at the bottom of the downlead will be a spotty nerd
chuckling with glee because he can overhear the mundane chat of
the local bobbies.
