You may be reading in something that is not there.  No mention of radiating,
just transmitting.  I know it's a pretty thin line, but a sharp lawyer could
probably convince a jury it's not the same as radiating.

Ignoring all the misstatements about capture area (capture area really has
nothing to do with physical size, it is a function of gain and wavelength),
they do make a gain claim.

"THE PERFORMANCE - It speaks for itself. Tests have measured the ISOTRONS to
transmit as well as a one-half wavelength dipole."

That's a problem. Saying it transmits "as well as a 1/2 wave dipole" means
zero dBd gain. It can't mean anything else.
