Laminated foil WiFi antenna. | QRZ Forums

Oct 24, 2019· I just have no idea of calculating the dimensions needed, or if a straight dipole would work rather than a folded dipole as the main element, or if the folded dipole could work if made of foil in 2 dimensions. Basically there is a lot I don't know! But the main reason for doing this is to learn about them.

Actually, we shouldn't be too harsh. The whole idea of a non-radiating transmission line was to somewhat remove one source of high voltage R.F. from the immediate vicinity of a gasbag the size of Milwaukee filled with hydrogen. For some peculiar reason, certain white-smocked hand-wringers were a bit nervous about sources of high voltage R.F. being right next to a gasbag .

Magnetic loop antenna might be a solution for 80m - KB6NU's Ham Radio Blog
