Use a directional antenna to increase the output signal in the desired direction. 2. Adjust the impedance of your antenna. The circuit you describe does not include an output impedance adjustment, so you have to use/make an antenna that matches this circuit. If you have the antenna connected directly to the output, and the length of the antennae is 1/4 the wavelength of the frequency that you are transmitting at, you should get maximum signal transmission. 3. Get an RF amp. (But remember, the FCC limits the broadcast power you can legally transmit without a license.)<br><b>References : </b><br> 1.
