Receiving radio waves from space is a difficult task that requires the use of instruments specially designed for radio astronomy: that’s why we designed the WEB300-5 3 meter prime focus parabolic antenna with supports. It was specifically designed to create a compact radio telescope with a altazimutal mount.
Large 3 meter diameter parabolic antenna
Radio astronomy studies signals that, in most cases, are very weak. So when you are studying frequencies higher than 1 GHz, it is necessary to use a parabolic antenna with a diameter as large as possible. WEB300-5 3 meter prime focus parabolic antenna with supports features a large diameter so it has high gain and resolution. This way you can capture weaker radio signals and study finer details.
Mesh construction – incredibly light
In order to allow installation and proper operation of a parabolic antenna on a not-too-expensive mounts, the main reflector of the WEB300-5 antenna weighs only 20 kg. The perforated surface also results in a low reflection of visible and infrared waves (ie, when the radio telescope points at the Sun, the illuminator and the LNA do not heat up too much) and a lower wind effect. The reflecting surface of this parabolic antenna (primary reflector) is composed of an aluminum mesh with 3x4mm square mesh size for optimum reflectivity of radio waves with frequencies up to 5 GHz.
Support for L-band feed and focus system
In order to study the weak radio astronomical signals, it is necessary to optimize the antenna by adjusting precisely also the focus point. For this reason 4 aluminum rods rigidly maintain the feed with LNA support (LNA and feed and not included in the WEB300-5). An appropriately-sized inner sleeve allows you to fine tune the focus of the system in order to maximize the gain. A special box insulates the LNA to minimize gain variations.
