In this video i explain how to build the Mortal-T Crossfire antenna for micros & toothpicks.
It is a trimmed down antenna that performs sufficiently good for micro builds and toothpicks.
A professional antenna builder would probably never make something like that but it remains "good enough", tiny and light for small builds that don't go that far.
I'm not an RF engineer, i explained some simple principles but left aside a lot of things like gain, impedance, etc. This antenna is called a lambda / 8 dipole.
Here's a table for various antenna lengths depending on your frequency : https://docs.google.com/spreadsheets/...

Some interesting readings :

Skip to 10:04 to get past the discussion and see the build.
if you want to make yours here's a cheap set of antenna wire with u.fl/ipex connector : https://www.aliexpress.com/item/32302...
