Magnetic fields attract magnetic or ferrous metals. If you use copper, aluminum or other non ferrous metals, then the electromagnet I linked to will NOT attract them.
Putting a magnetic field around your device may cause the signal to be reflected back INTO the device instead of to the target (space).
This is the way CRT televisions work. A beamsource shines a electron beam at the screen. Electromagnets then direct the beam, without amplifying it, to the individual pixels on the screen to make the picture.
The magnetic field PULLS the beam to put it on the screen.
Oscilliscopes do the same thing. The lines you see the screen are made from a stationary signal-beam that uses magnetic fields to distort it to make the picture. The objects you are testing with the scope feed the magnetic field. so when the item goes higher, the magnetic field goes higher and it pulls the beam up further on the screen.
You may want to consider a larger crystal or an amplifier.
Magnetic fields like those used in transformer amplifiers, have the signal that needs amplified running through them. It isnt good enough to have the signal near the magnetic field.
So if you could SEE the beam you are transmitting, you could use magnetic fields to AIM it better, but it will not amplify the signal.
