Default Eaton 94455-1 biconical EMC antenna. Antenna factor ?

Hello,

I am looking for the antenna factors table for a Eaton 94455-1 biconical
antenna (20MHz to 200MHz). Does someone have a calibration table for a
similar antenna around, or a manual for this antenna model ?

More exactly I have found some K factors for it but they seems wrong, except
if I'm wrong with the units somewhere. I have a table with figures ranging
from "47" (65MHz) up to "59" (200MHz). Assuming these figures are in dB/m
this would give a gain of -44dBi at 160MHz (K = 20 log(F in MHz) - G - 29.8
isn't it ?). The result is not reasonnable... and not at all compatible with
the measurements.

Are my K factor figures wrong, or is my calculation wrong somewhere ?

Thanks for your help !
Yours,
Robert
