Today was a good day to ride slowly and with a de-tour back to home. Putting my TTN test node (with a 1/4 Lambda wire antenna on it) in my backpack and with a active [TTN Mapper - Android app](https://play.google.com/store/apps/details?id=com.jpmeijers.ttnmapper) a coverage plot was forming.

It's good to see how concrete structures attenuate the signal between the node and the gateway.

Next time a TTN Mapper drive with a better ground-plane antenna mounted on the back of my bike.
