If antenna emits electrons (longitudinal Tesla waves) than the ground is the source of them. Having built one of these things or very similar (or more properly, my tween daughter did).. Hook a 6-10 foot long piece of wire to each of the clips and stretch them out and it works pretty well. In my case, we threw a hunk (precision measurement.. probably about 10 ft) of wire over the curtain rod, and laid the other one out across the floor, transmitter sitting on the desk. The "other one out across the floor" works as the chassis. The chassis is enough for the small power at higher frequencies. Your phone cell has the chssis (ground) also. S* yeah.. but at 1 MHz ish... a bit of length helps a lot. |
