Description:
From sea-stained dispatches to data sent back from deep space, Southern Signals is the story of Australia’s use of communications to bridge vast distances through war and peace, exploration and growth.
Communications have been vital at every stage of Australia’s history. From the time the First Fleet transport ship Prince of Wales limped back into port eight months after leaving Sydney Cove, to the breakneck rush during the 1970 Apollo 13 crisis to bring Parkes’ famous radio telescope on line, this book shows how adoption (or not) of emerging communication technologies has influenced key events, and formed the. backbone of Australia’s development as a society and relationship with the world.
Chapter topics include: dispatching mail to Britain from a convict colony, and then around a big country; the arrival of telegraph, telephone, and television; wireless radio and Antarctic exploration; wireless radio entering Australian homes; the coming of airmail; Australia’s role in televising the moon landing; communications in search and rescue, Australian newspapers; the internet and the opportunities and risks of the future.

Nice and big
Color: 2Pcs-Large L Hooks-Black
They're strong the thicker the steel or iron you attach it to the better it sticks.
It has a rubber coating over them magnets so they won't shatter when you stick them.

Awesome -- they work perfectly
Style: Updated 3.46in Magnet L Red Hooks 2PCS
Got these to store a DeWalt cordless drill and impact driver on the side of a Gladiator garage cabinet -- and they work perfectly for that. The magnet is incredibly strong, easily supporting the bare tools, and seems even to work perfectly well with an 8ah XR battery on the tool -- not that it's necessary since I don't store them like that. I like that the magnet is padded with rubber. Very nice units, I will get more for sure to store other items.

Incredibly strong magnets and thick, robust hooks. Excellent combination!
Style: Updated 3.46in Magnet L Red Hooks 2PCS
These magnetic hooks are really strong. Seriously! Each part is made to carry weight and last. The hooks are built out of thick steel stock. They bolt up to large magnets that grab onto steel surfaces and won't let go. The cabinets in my shop are all steel so these worked perfectly on the sides of the lower units. I have a few #12 AWG extension cords that are bulky and heavy. Truthfully, I didn't think these hooks would handle them. They do without any issue. Another application is a 30' long #10/4 AWG SO cable that powers my powder coating oven. It's usually unplugged and wrapped up. It would often end up on the floor where it was constantly in the way. The outside of the oven is all steel but I didn't want to make holes in it for cable hangers. Again, I didn't think that these magnetic hooks could possibly be strong enough to handle the weight of that cable but they do. And once they're attached, it takes a lot of effort to remove them! Amazing performance!!
I'm thrilled with these magnetic hooks. They are super strong and, obviously, simple to use. Importantly, they stay in place as they should. I wholeheartedly recommend these hooks to anyone. Great product!
Incredibly strong magnets and thick, robust hooks. Excellent combination!
