Open the scad file to tune the parameters.
Cable length (squares) is computed from the frequency.

Openscad console is printing the informations to finalize the antenna.

E.g, with frequency 2430MHz.

ECHO: " Diamond (one of the 4) total length: ", 123.371
ECHO: " Diamond side (1/4 length): ", 30.8428



Always check your build (continuity, ...) BEFORE connecting a new antenna to your TX/RX !
