Bandwidth and antenna windings

Our dipole antenna element was fixed on wooden frame using nails. The dipole wire was wound around a nail to make it taut. When we introduced a wound around the nail, they acted as an inductors on ends of the wire (Rad's comment with a chuckle).

We need to put plastic caps on each end, and then use some material to fix the dipole wire, possibly some rope or hard plastic cover on usual copper wire. see this link.




As for the interference outside the "allowed band" of the dipole, let us wait for Onkar to fetch the co-axial cable from NCRA/TIFR, Pune.
