Expressions are found for the fields produced by TM and TEM modes along a finitely conducting biconical antenna. Expressions are also found for the TM and TEM fileds along a biconical antenna having a lossy dielectric coating. It is shown that the antenna losses produce an anntenuation of the the fields along the antenna. It is found that because there is a dispersion of the fields along the biconical antenna, the attenuation produced by the losses is, in genaral, not characterized by simple exponential.

A solution is obtained for the fields of the TEM wave along a biconical antenna coated with a dielectric cone having a permititivity significantly different from that of the surrounding media. It is shown that the principal effect of dielectric coating is to reduce the wave length along the antenna.

The energy transfer along the biconical antenna is investigated and a physical interpretation is given for the behavior of the fields along the antenna, based on the results obtained.
