3.3.3.2.1.7.- Field strength
This unit corresponds to a measure of intensity of electric field in a given point. For the
accomplishment of this measure we should take into account all the elements, from the signal
collection system used (antenna) up to the measuring equipment (prior, cable ...).
For the H60, this unit is calculated for a Televes DAT-HD antenna and 10 meters of cable T100
(for more information, please visit http://www.televes.com).
