Hi,

first of all thank you for the great YouTube tutorials !

Regarding one of them (Using Inexpensive 433 MHz RF Modules with Arduino) I'd like to put the TX module

into a PVC box and on the top of it I'll screw a female RCA socket. With a RCA male plug I'll connect the antenna.

The antenna is 17.32 cm and now here comes my doubt. From the module to the female socket i have a wire of +/- 4 cm. Should I consider these 4 cm as an antenna ?

Perhaps were it better use a 4 cm shielded cable ? 

Thank you in advance 

Regards

Roberto
