10 foot sections available upon requestĮlliptical aluminum reflectors provide a line source where one focal point is at the center of the UV lamp, the other focal point is at the surface of the curing substrate. For this reason, only two of our four profiles come with provisions to accommodate reflective inserts.įour standard styles are available, two elliptical and two parabolic diffusers.ħ" Parabolic Reflector comes standard in 5 foot long sections. Even in these cases, our UV reflector extrusions are very cost effective and tend to be less expensive than a new UV reflective liner. Expensive UV reflector liners or reflector sheets are not required however, these reflector sheets may be considered in extremely messy environments where ink or varnish spatter tends to degrade the reflector surface. This high UV reflectance is approximately 90% and unlike other aluminum, this special grade resists tarnishing and corrosion. The inside surface is highly polished to yield an efficient transfer of UV energy from the uv bulb to the curing substrate. Our extruded reflectors are made of specially processed 6061-grade aluminum. For higher power applications it is best to enclose the reflector in a housing, using forced air-cooling to draw air from both ends to create an end cooled reflector assembly, or a center hole on the top of the housing to create a center cooled reflector assembly. Heat from the lamp is absorbed by the aluminum reflector and dissipated into the fin structure opposite the reflective face. Medium pressure lamp power rating from 100 to 600 watts per inch are commonly used. These profiles are time tested, proven designs, to focus UV light from medium pressure mercury and metal additive lamps on to a curing substrate. Our highly polished Aluminum reflector extrusions allow engineers to cost effectively build their own UV curing system without investing in expensive extrusion dies, long lead times, and minimum draw charges. All deliver a reliable, high bandwidth link to the satellite on all maritime frequencies, ensuring continuous availability of voice and data communications regardless of location and conditions.Beam Profiles | Ray Trace | Custom Designs | Building a Reflector Assembly Parabolic antennas are classed as ‘high gain’ systems and have very low limitations on the amount of bandwidth they can transmit and receive, making them ideal for next generation networks that serve as a backbone to digital transformation and smart shipping.Ĭobham SATCOM offers a complete range based on decades of experience in developing and maximising the potential of the parabolic design. Parabolic antennas come in almost any size, from compact 60 cm VSAT through to 6 metre diameter ground station tracking systems. The digital transformation of the maritime industry is already leading to fully autonomous shipping: satellite communication is a must to succeed with autonomous shipping and choosing the best satellite and radio communication platform to implement ‘smart’ procedures can benefit your fleet and business here and now. ![]() Without this, the parabolic shape of the antenna is not enough to ensure accuracy in pointing the antenna towards the satellite. ![]() To ensure a stable link to the satellite, maritime parabolic antennas must feature stabilisation, a powered, mechanical system that can counteract the movement of the vessel in six degrees of freedom. When receiving data, the dish bounces the radio signal to the feed antenna, which converts it to a digital signal and sends it further into the network. When transmitting information, the feed antenna converts a digital signal to radio and directs it at the parabolic dish, which then bounces the signal back up to the satellite. ![]() Parabolic antennas feature a parabolic dish and a small feed antenna. A key reason for this is that the parabolic shape of the reflector makes it easy to direct the radio signal, and on a mobile platform (i.e., a ship), this makes all the difference. Parabolic reflector antennas, also known as satellite dishes are the industry standard antenna type for maritime satellite communications. Reliable Wi-Fi and internet is key to seamless communications and entertainment at sea. With the proliferation of smart devices in their lives, ship passengers have come to regard easy access to social media, or video on demand at sea, as essential components of the passenger experience.
