Fantastic article.

I found a slightly clearer diagram of the Cutler array:

> Therefore, the antenna cables are connected to a deicing system. When in use, it heats the wires by running a 60 Hz electric current through them. The power required to deice one array within a reasonable time is 3 MW or more – considerably higher than the transmitter output power.

I love that they de-ice the antenna array by plugging it into the grid and sending 3 megawatts into the wires

I didn’t know there was one of these in Australia, the Naval Communication Station Harold E. Holt.

The man who mysteriously disappeared whilst swimming has a Naval Communications station and a pool complex named after him?! Amazing!
As an Aussie, it’s always amused me that we managed to name a public swimming pool after a Prime Minister who (at least as the official story goes) died whilst swimming.
