I am using a rf Module 433MHz , may i fit the antena at my roof top extending via a coaxible cable ?
what is the consideration for it ,
is count coaxible cale length for the antena cm ?
is it possible

It depends. If the transceiver is designed for 50 ohm antenna impedance, it can be extended with a 50 ohm coaxial cable of arbitrary length. Cable is however causing some attenuation, cheap RG-58 e.g. 0.4 dB/m at 433 MHz.

Hi,

Select the cable according
* frequency range
* characteristic impedance
* attenuation per length

All three values should be given in the cable datasheet...and fit to your application.
