Totally misleading title. ### 1/5 — Needs to be updated *2020-12-06* I can’t get the app to open in iOS 14 ### 4/5 — It works *2013-08-18* I've built a couple of antennae using the dimensions specified by this app and after just a little fine tuning they have proved to be very successful. ## Frequently asked questions about Antenna, CW, Morse, DTMF tools ### What is Antenna, CW, Morse, DTMF tools used for?
