    Radio frequency circuit 30 meter to 500 meter at 1.5GHz

    Sir My problem,I have device transmit signal up to 30 meter, output power at antenna input is :1W,antenna said -75dbm omnidirectional (signal strength @30 meter). all that at 1.5GHz. All i need is how to increase range up to 500 meter, to have signal strength=-75dbm @500 meter. all that at 1.5GHz.

    Radio frequency circuit 30 meter to 500 meter at 1.5GHz

    I want to re-transmit it up to 500 meter. I have transmitter give 1 Watt at output ,what i have in mind that is: 1- put amplifier instead in cascade with device output. 2- this amplifier should have 0db in and 20db at outpt. 3- omni-directional antenna with 20 dB gain Is this Right??
