Cable nodes

You may have noticed in the cable trenching plan, that the cables flow in from the different antennas, joining with each other along the way. These join points are referred to as "cable nodes". The cables themselves are in flexible agricultural drain pipe. A larger piece of this is them cut to provide the node. A cap them goes on top of this to allow access later for drawing the cables.

This is what the completed node looks like, but still before the node cap has
been applied. Note the thin what drawstring. (Photo: D. McKay-Bukowski)

Only the main branch pipes have drawstrings. The other pipes between the nodes and the antennas themselves are sufficiently short, and the pipes otherwise empty, that two cables can easily be pushed through.
