This gives the resulting telescope great beam properties. However, it also makes it difficult to install.
Here, Griffin Foster (U.Oxford) and Mayaane Soumagnac (ENS-Lyon, France) start setting up the cables for one of the LBA aerial locations. There is a six-page document describing the procedure, as many of the steps done in this initial phase are critical to subsequent phases of the installation.

"You are in a maze of twisty little trenches, all alike". Here the LBA team are busy placing the LBA cables in place. From left to right: Harry Smith, Griffin Foster, Mayaane Soumagnac, Danny Price and Jack Hickish.

Our equivalent of Ariadne's Thread: countless cable trenching plans, diagrams, lists and tallies are used to keep track of the deployment within the LBA. However the ultimate is this dual-core backpack-computer, with headset, scanning gun, barcoded-trench plan, LBA antenna checking software, text-to-speech synthesiser and rocket launcher! (Okay, okay... maybe not the rocket launcher.)
