Many amateur radio operators in the US take part in Field Day. This is an annual exercise that asks radio operators to set up transmitters in conditions that may arise after a natural disaster. Usually this means taking over a park or campsite, bringing generators and portable devices, and getting everything up and running for the weekend before tearing it down again.
It’s not a big field day without electricity. That is why most stations use a generator, solar cells or even batteries. Today you will likely need an internet connected computer to do logging and other functions. [HamRadioConcepts] has a video (see below) that shows how they have hit the internet from far for their Field Day site.
The key that made this possible is the fact that most cable companies are now broadcasting public WiFi hotspots from home and commercial routers. Usually, you have to decide against it, and most people don’t. If you have home internet with this provider, you can usually use these hotspots for free.
In this case there was no hotspot within range, but there were several on the other side of the lake. With the help of a bowl and a 1-watt USB network adapter, they were able to access a computer on the network and then use the connection sharing to spread the WiFi across the Field Day site.
If you prefer to roll your own antenna, we can especially help if you have one a wire mesh spoon.
