Hi Forum,
I plan to reduce the transmitted power of standard 433MHz transmitter .
Following is the Module and its parameters ;
Frequency Range:315 / 433.92 MHZ.
Supply Voltage: 3~12V.
Output Power : 4~16dBm
Circuit Shape: Saw
As it can be seen it is transmitting around 16dBm at 12V input would be good for 300meter distance or so . I want to employ Pi atteunator on this to reduce the power to such a level that is is able to transmit 5 meters approx.
I plan to do this;
Transmitter Ant------>Pi Atteunator----->loop antenna.
Can anyone help me with what amount of atteunation is required to achieve this distance ?
Thanks
