    Abstract: The present disclosure describes a pultruded panel profile (40) with a sandwich structure and a method of manufacturing such a panel profile. The sandwich structure has at least one a core layer (42) and surface layers (44) on both sides of the sandwich structure. The core layer (42) comprises at least one signal window section (46) made of a signal-transparent material, the signal-transparent material being substantially transparent to at least one wireless signal. The core layer further comprises a peripheral section (48a, 48b) surrounding the signal window section (46), the peripheral section (48a, 48b) having a different material composition than the signal window section (46).

    Abstract: Invention relates to a radome casing and method for its manufacturing. The radome casing comprises WALLS (6, 11) of composite material which includes reinforcement fibers (8) and matrix resin (19) binding the fibers together. The walls include a radiation transmission window (11) through which the radiation of a radome antenna passes when the radome antenna (2) is mounted inside the radome casing (1). The amount of fibers in the radiation transmission window (11) is reduced to be less than 80-5% of the amount of fibers elsewhere in the casing walls (6). The reduction of reinforcement fibers in the radiation transmission window (11) reduces attenuation of the high frequency radiation.
