DESCRIPTION
1/4 λ Ground Plane wide-band antenna for base station service. It is made of aluminium and hi-
quality materials to get the best efficiency and robustness. Its radial whip is earthed to be protected
against the static discharges. GP 87-108 LB is developed for FM radio band and GP 108-136 LB
is particularly recommended for the aereonautic band service.
