Science, Technology, Engineering and Math: Education for Global Leadership >>> Amateur Radio YL's



“[Science]“[Science] is more than a school subject, or the periodic table, or the properties of waves. It is an approach to the world, a critical way to understand and explore and engage with the world, and then have the capacity to change that world..."

— President Barack Obama, March 23, 2015

The United States has developed as a global leader, in large part, through the genius and hard work of its scientists, engineers, and innovators. In a world that’s becoming increasingly complex, where success is driven not only by what you know, but by what you can do with what you know, it’s more important than ever for our youth to be equipped with the knowledge and skills to solve tough problems, gather and evaluate evidence, and make sense of information. These are the types of skills that students learn by studying science, technology, engineering, and math—subjects collectively known as STEM.

Yet today, few American students pursue expertise in STEM fields—and we have an inadequate pipeline of teachers skilled in those subjects. That’s why President Obama has set a priority of increasing the number of students and teachers who are proficient in these vital fields.

Projected Percentage Increases In STEM Jobs from 2010 to 2020: 14% for all occupations, 16% for Mathematics, 22% for Computer Systems Analysts, 32% for Systems Software Developers, 36% for Medical Scientists, 62% for Biomedical Engineers
The need

All young people should be prepared to think deeply and to think well so that they have the chance to become the innovators, educators, researchers, and leaders who can solve the most pressing challenges facing our nation and our world, both today and tomorrow. But, right now, not enough of our youth have access to quality STEM learning opportunities and too few students see these disciplines as springboards for their careers.expand/collapse

The goals

President Obama has articulated a clear priority for STEM education: within a decade, American students must "move from the middle to the top of the pack in science and math." The Obama Administration also is working toward the goal of fairness between places, where an equitable distribution of quality STEM learning opportunities and talented teachers can ensure that all students have the chance to study and be inspired by science, technology, engineering, and math—and have the chance to reach their full potential.expand/collapse

The plan

The Committee on STEM Education (CoSTEM), comprised of 13 agencies—including all of the mission-science agencies and the Department of Education—are facilitating a cohesive national strategy, with new and repurposed funds, to increase the impact of federal investments in five areas: 1.) improving STEM instruction in preschool through 12th grade; 2.) increasing and sustaining public and youth engagement with STEM; 3.) improving the STEM experience for undergraduate students; 4.) better serving groups historically underrepresented in STEM fields; and 5.) designing graduate education for tomorrow's STEM workforce.expand/collapse

Supporting Teachers and Students in STEM

At the Department of Education, we share the President’s commitment to supporting and improving STEM education. Ensuring that all students have access to high-quality learning opportunities in STEM subjects is a priority, demonstrated by the fact that dozens of federal programs have made teaching and learning in science, technology, engineering, and math a critical component of competitiveness for grant funding. Just this year, for the very first time, the Department announced that its Ready-to-Learn Television grant competition would include a priority to promote the development of television and digital media focused on science.

The Department’s Race to the Top-District program supports educators in providing students with more personalized learning—in which the pace of and approach to instruction are uniquely tailored to meet students’ individual needs and interests—often supported by innovative technologies. STEM teachers across the country also are receiving resources, support, training, and development through programs like Investing in Innovation (i3), the Teacher Incentive Fund, the Math and Science Partnerships program, Teachers for a Competitive Tomorrow, and the Teacher Quality Partnerships program.

Because we know that learning happens everywhere—both inside and outside of formal school settings—the Department’s 21st Century Community Learning Centers program is collaborating with NASA, the National Park Service, and the Institute of Museum and Library Services to bring high-quality STEM content and experiences to students from low-income, high-need schools. This initiative has made a commitment to Native-American students, providing about 350 young people at 11 sites across six states with out-of-school STEM courses focused on science and the environment.

And in higher education, the Hispanic-Serving Institutions-STEM program is helping to increase the number of Hispanic students attaining degrees in STEM subjects.

This sampling of programs represents some of the ways in which federal resources are helping to assist educators in implementing effective approaches for improving STEM teaching and learning; facilitating the dissemination and adoption of effective STEM instructional practices nationwide; and promoting STEM education experiences that prioritize hands-on learning to increase student engagement and achievement.

beverage antennas


here is some more information on beverage antennas w8ji thanx

beverage antennas link


My History With Beverages

I originally began experimenting with long, low, wire antennas in the 1960's. Even though I had a working mostly homebrew station, I now realize I had only a small idea what I was doing, and almost no understanding of what made antennas work.

My entry into Ham radio was from modified broadcast radios, and the very active 160-meter mobile group in Toledo, Ohio. I always thought the longer the antenna, the better the "pickup". was fascinated by the distant AM broadcast, lower shortwave, and 160-meter signals heard with long antennas. My early antennas were nothing more than hundreds or thousands of feet of very thin magnet wire, strung over tree limbs and along telephone poles (which had steel climbing pegs), all through a typical crowded 1950's suburban neighborhood. Unfortunately my early experiments were hampered by lack of room. Thin magnet wire, unwound from early-radio speaker field magnets, strung in the middle of the night through a crowded suburban neighborhood across neighbor's small lots, doesn't stay up long.

In the early 1970's, I moved to a house with several acres of woods. The soil was a very wet, sandy, black loam. A neighbor just north of me, W8FPU (Parker) was actually working a couple of VK's on 160-meters, something very rare at the time. Using information from a series of engineering lectures by John "Jack" Kuecken (now SK) and correspondence with Stew W1BB, I installed my first "real" Beverage antenna. I was delighted to find a large improvement in weak-signal reception from very simple, inexpensive, easy-to-install wire antennas. Eventually, that system evolved from a few long single wires to a two-wire reversible system. The two-wire system used two Beverages, oriented 90 degrees from each other. This gave four direction coverage. That system, with the addition of an in-phase and out-of-phase combiner, evolved into a forced-null system using just two reversible antennas. This was before binocular cores were available, and ferrite beads were just appearing. At the early date, I used a series of 73-mix beads to make my transformers, even publishing a few articles in small newsletters.

I continued to improve or refine my Beverage antennas over the years. Virtually all of my Beverage antennas now are arrays of multiple Beverages, not just single wires. While my large circle arrays of verticals, or broadside endfire arrays of verticals, are about even with two long phased Beverages, the Beverage arrays are simpler systems. Arrays of broadside Beverages remain my primary DX receiving antennas for the lowest bands. There isn't any other receiving antenna that is as simple, as easy to construct and maintain, and as foolproof as a Beverage! The only significant Beverage disadvantage is the long physical length required, and maintenance of a very long antenna. If we want significant directivity, Beverages (like all long wire arrays) require a great deal of space .

Testing and Comparing Antennas

I work a little different than many or most people when experimenting, always A-B testing and comparing antennas over time. This is partly because a newer, bigger, or better looking antenna always feels better. Even before something is used, especially if the "something new" involved effort or expense, we can "like" it and become emotionally invested in it. We want something new to work better, so we look for everything "good".

I credit a 7th and 8th grade science teacher for educating students about this phenomena. Early in school, a science teacher at Olney middle school in Northwood, Ohio demonstrated how easily and often false conclusions are reached, based on feelings about results or past performance memory. One year of science with Mr. Kohler, when I was 12 or 13 years old, changed how I look at many things in life. Because of Mr. Kohler, I almost always retain a reference or control, try to use direct measurements of what I actually want to know, and use multiple methods when possible. Mr. Kohler demonstrated how easy it was to reach false conclusions, unless we use valid measurements.

Most antenna myths and misconceptions, many making it into print in articles, come from repeating feelings or unsubstantiated claims, or are based on improper measurements or models. I've seen comparisons years apart, going on memory of how signals were on some other antenna that was long gone!

I presently have a great deal of room, with wiring in place to install multiple antennas, and reasonably good test equipment. This allows installation of multiple antenna systems at the same time, which allows direct comparisons over time, as well as measurements. I constantly refine antenna systems by comparing systems against each other for extended periods of time, usually more than a year.

Bent Dipoles


here is some great information on dipoles thanx to KK4obi

Bent Dipoles link

there is more if you click on the link


This web site is devoted primarily as a resource for amateur radio operators
to see what happens if they bend a half-wave dipole.

The performance of a dipole is highest when it is not bent. When a half-wave or full-wave dipole is bent: the gain goes down; the resonant length gets shorter; the frequency goes higher; the impedance decreases. Only when the length is three or more half-wavelengths can bending increase gain as you transition into gull-wing, half-rhombic V and rhombic antennas.

To help understand what happens to a bent dipole, you will see graphs showing the changes in Gain, Resonant Length, SWR, etc. as well as polar charts of far field radiation patterns and 3D flyover views as a bend point is moved or angle of bend changes.

1. We start with bending the ends of an ordinary center-fed dipole limited by an attic, garden, wall, etc. or to reduce turning radius. We than look at bending a dipole in the middle... up and down, side to side... to form V or L-type configurations.
See illustrations of all eleven studies at: Center-fed Dipoles.

2. The second phase looks the same set of configurations but by feeding a dipole off-center, (OCF). This an outgrowth of antenna/coax matching because of the low impedance of dipoles in the V or L-form, not for multi-band application. However, as part of this, there is a study related to feed points up to the 6th harmonic.

3. The third phase deals with slow wave antennas for size reduction- primarily for cell phones, routers, printers, remote control, as well as radio frequency identification (RFID) for merchandise or toll/parking collection- but applied to amateur radio antennas. These studies include meander, zig-zag and catenary curve methods.

4. The information presented is derived from a mixture of practical antenna prototyping and wire antenna modeling used to find out what is going on and "what happens if...". The software used is 4NEC2, a Windows compatible program based on an NEC-2/ NEC-4 core (Numeric Electromagnetics Code). It is used to create, view and check antenna designs and generate displays of radiation patterns. Of particular importance for the studies reported here is its optimizer function which automatically adjusts antenna variables to find the best Gain, Resonance, Standing Wave Ratio (SWR), Efficiency, Front-to-Back ratio or combination thereof. Its sweep function then graphs Far Field Radiation Pattern and 3D view plus Reflection Coefficient, Reactance, Impedance and Phase over the range of frequencies of interest.
