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.
