Big Red Radio Telescope 12-Month Status Report
WKU Sisterhood Grant 110222: Big Red Radio Telescope 12-Month Status Report Steven Gibson, November 11, 2020 1. Overview and Goals The Big Red Radio Telescope project is converting an old 10-foot satellite TV dish and receiving system into a scientific instrument that WKU students and faculty will use to explore the “invisible” universe for education, research training, and public outreach. Goals of this effort include: 1. Foster significant collaboration between the WKU astronomy, physics, and engineering pro- grams in the design and construction of the radio telescope. 2. Give students in these programs hands-on experience in many aspects of a complex technical project, providing invaluable professional training. 3. Augment student education and career training in several areas, including direct and remote astronomical observations, classroom demonstrations using live and recorded telescope data, computer interfacing and control systems, mechanical engineering design and build experience, and complex project management, coordination, and communication. 4. Working with WKU’s Hardin Planetarium, enrich public education and outreach to school groups and the broader community by using the telescope and related concepts to demonstrate the “invisible universe” revealed by radio waves; WKU students involved in this effort will also gain science education experience. 5. Raise the public profile of the University, and support its mission as a student-focused uni- versity serving the region and providing exposure to science and critical thinking, while also strengthening ties with the local community. This project has been going since 2016 but, with the help of the WKU Sisterhood, it should soon see the full assembly and installation of a working radio telescope. -
Satellite Dish Addendum
SATELLITE DISH ADDENDUM Under the Federal Communications Commission order, Resident has a limited right to install a satellite dish or receiving antenna on the leased premises. Owner may impose reasonable conditions to installing such equipment. Number and Size: You may install only one satellite dish or receiving antenna on the premises. A satellite dish may not exceed one meter in diameter. An antenna may receive but not transmit signals. Location: Location of the satellite dish is limited to (a) inside Resident’s dwelling, or (b) in an area outside resident’s dwelling such as a balcony, patio yard, etc. of which Resident has exclusive use under Resident’s lease. Installation is not permitted on any parking area, roof, exterior wall, window, windowsill, fence, or common area, or in an area that other residents are allowed to use. A satellite dish or antenna may not protrude beyond the vertical and horizontal space that is leased to Resident for Resident’s exclusive use. Safety and Non-interference: The installation: Must comply with reasonable safety standards May not interfere with our cable, telephone, or electrical systems, or those of neighboring properties May not be connected to our telecommunications systems and May not be connected to our electrical system except by plugging into a 110-volt duplex receptacle. If the satellite dish or antenna is placed in a permitted outside area, it must be safely secured by one of two methods: Securely attaching it to a portable, heavy object such as a small slab of concrete or Clamping it to a part of the building’s exterior that lies within Resident’s leased premises; (such as a balcony or patio railing). -

The design and layout of antennas is an extension of that practice. This application note will provide some of that basic insight on board layout and antenna design to improve our customers’ first pass success. Antenna design is a function of frequency, application, board area, range, and costs. Whether your application requires the absolute minimum costs or minimization of board area or maximum range, it is important to understand the critical parameters so that the proper trade-offs can be chosen. Some of the parameters necessary in selecting the correct antenna are: antenna © Freescale Semiconductor, Inc., 2005, 2006, 2012.

Antenna Articles Collection of Short Articles Relating to All Manners of Antennas
Antenna Tips page 1 of 31 Source : http://www.funet.fi/pub/dx/text/antennas/antinfo.txt Antenna Articles Collection of short articles relating to all manners of antennas. These articles are the hard work of Wayne Sarosi KB4YLY (995 Alabama Street, Titusville, FL 32796) SUBJECT: Circular Polarized Antenna There has been a request for a series on 'CP' antennas. The term 'CP' eluded me at first as I was not familar with the abriviated designator for circular polarization. At work, we just use the entire words. I'm going to begin this ten part series with the basics. After researching CP designs with a few engineers and fellow hams, I found that they knew very little about the subject. I also found I didn't know quite as much as I thought I did about circular polarization. So starting at the begining will help all out. First, let's discuss the circular polarized wave. There seems to be conflicting standards used by the world of physics and the IEEE. I found this to be true in four reference manuals including the ARRL Antenna Handbook. At least it's stated right up front but biased according to which text you read. We will follow the IEEE/ARRL standard in the following series for obvious reasons. There are two types of circular polarization; right and left. All of us agree up to this point. According to the ARRL Antenna Handbook, the following statement: 'Polarization Sense is a critical factor, especially in EME work or if the satellite uses a circular polarized antenna. -
Design and Construction of a Cost-Effective Parabolic Satellite Dish Using Available Local Materials
International Journal of Advanced Materials Research Vol. 5, No. 3, 2019, pp. 46-52 http://www.aiscience.org/journal/ijamr ISSN: 2381-6805 (Print); ISSN: 2381-6813 (Online) Design and Construction of a Cost-effective Parabolic Satellite Dish Using Available Local Materials Gbadamosi Ramoni Adewale * Faculty of Science, National Open University of Nigeria, Akure, Nigeria Abstract Communication through satellite is very important at this information age. It can provide complete global coverage. It can be used to send and receive information in remote area where other technology may fail. Communication signals are sent in form of electromagnetic signal which are intercepted by the parabolic dish. The offered high-efficiency and high-gain by the parabolic dish makes it appropriate for direct broadcast satellite reception. However, parabolic dish procurement in developing countries is very expensive. This makes it to be unaffordable to majority of the masses. This paper focuses on design and construction of cheap parabolic satellite dish using local readily available materials. An indigenous technology is exploited to achieve the goal of this work. The paper describes from the scratch, how to design and construct a parabolic dish that can be used to intercept electromagnetic signals from the satellite stationed in the space. The proposed design approach offers a number of advantages such as cost-effectiveness and high simplicity. These are due to the fact that; it can be effectively developed with the easily available materials. Besides, it development demands neither special/long time training nor skill. Thus, both technical and non-technical personnel with minimal training can construct it either for commercial and/or personal use. -
