C's may get degrees, but only an A+ essay earns a place on your grandmother's fridge or your own fridge. Have you been busting your little collegiate butt just to get mediocre results? Well, tell Granny to get the magnets ready: follow these steps, and take your term papers to the head of the class.
The building steps are simple:
1. Print out the scaled Yagi antenna template* (download from next step).
2. Trim paper clips to size and glue them to the template.
3. Use Popsicle sticks to build the antenna's backbone and hold it together.
4. Connect the USB device to the antenna.
*I used a Yagi modeler java applet to generate the diagram. This modeler applet is found on many websites (google "yagi modeler") and its owner is .
The modeler gives a diagram and the elements' lengths and position. I carefully scaled the diagram and turned it into a template in order to make the building process easy.
You can visit awesome website to get more details on using the modeler for this 15 element Yagi and other fine antenna projects, such as a 20 element WIFI Yagi .
The average person is not going to be able to make this because it leaves out the most important step; so I'll try to explain without going into the math : Matching the impudence of the feed line (the wire that connects to the folded over paper clip). RF signals at this high frequency is VERY sensitive to length. It is critcal to cut the lengths perfectly, also the lengths are for copper wire not steel. So the best material would be solid copper wire that you can buy at the hardware store. I used 18ga and kept the lengths within a millimeter of the size.
Okay well I read through the entire post and I saw many things that made a lot of sense, also saw a lot of unnecessary flaming, but I do have a few comments to make. Right off the bat the one individual that asked about having his modem in the basement with a rotating antenna on the roof needs a reality check. Overlooked in the connecting the USB dongle to the antenna was the transmission line length, for these frequencies it should be as short as possible and a multiple of 1/2 wavelength I'd suggest as close to 2.41 inches as one could manage (use a small diameter 50 ohm coax). Take the dongle apart and connect a USB extension cable to it and mount it directly on the antenna assembly. Paper clips vs copper, at this frequency it's not going to make much difference, however the specific model was generated using 14awg copper. Someone said glue it all to cardboard then cover it with more cardboard actually a strong and stable design, original author said build around popsicle sticks(wooden), both are subject to absorbing moisture from the air and either can have a poor dielectric constant, I would suggest some kind of plastic (they make popsicles with plastic sticks). The lengths of the elements, the spacing between them, and keeping them all in the same plane and parallel to each other is the most important consideration. The driven element, #2 in this design: that one I would make from 14awg copper, I'd make a simple dipole rather than a folded dipole, I would take two pieces of wire make 90 degree bends in them cut the bent part to about 1/8 inch and attach my transmission line. Take a piece of heat shrink cut two notches in it about 1/4 inch apart and insert the wires into it and shrink it, maybe reinforce the space in the center (break a tooth from my comb and stick it in the middle before heating the shrink?) cut it down to the correct overall length and insert it last. If you use the folded dipole make sure the folded part is perpendicular to the plane of the rest of the antenna and use 300 ohm twin lead to connect to the dongle, but your SWR will probably be much higher, reducing your effective gain and possibly resulting in early failure of the dongle. Horizontal vs vertical, after you have your antenna connected and have connected to some network you can try rotating it about its horizontal axis to see if you can get a better aspect on the other antenna (more bars). All in all though good job to Biotele, it's cheap, it's easy, and if done right will provide excellent results. I did not build this antenna, but I built 2 antennae very similar before reading this post, My son and I live almost 2 miles apart and either of us can stream 1080p movies from the other's house during a thunderstorm.
While keeping within the law, who an employer hires is pretty much her determination--but one that ought not be taken casually. Hiring the right person for the job may be the most critical management decision you will make. Consider the farm manager who lost $80,000 in alfalfa. He had trusted an employee who claimed to know how to bale. Or, the thousands of dollars lost by a hog producer in only three months as a result of hiring the wrong person.
I'd like to start this share with my understanding of shame and guilt. I am ashamed when I think of some decisions I have made. I feel ashamed of the actions of an alcoholic father and of the house I grew up in. This is a deep feeling that I am not good enough -- that's shame to me.
Guilt is a valuable thing. It's a feeling we get when we are doing something that is against our own value system. Sometimes it's the thing that keeps us honest.
Much of my 4th Step involved shame. My reasons for not wanting to do it were that I was afraid everything was wrong with me. After working it, I found that I was not a shameful being, but a human -- one who makes mistakes and is equal with others.
I think that the 8th Step is about guilt. What actions have I taken in the past that went against my value system. Whom did I harm with my laziness, compulsions, dishonesty, bad temper?
This was a very scary step to me -- well actually in my usual habit, I was looking ahead to the 9th Step, so avoiding the 8th.
We can use our 4th Step Inventory to see many of the people who should be on our list. I've been to a meeting where they just handed out a paper and pen and said "make the list". It's something most of us already know --especially doing it the first time--so making the list itself should not take long. I also believe that we need to have our own names on the list. We have hurt ourselves probably more than anyone else.
But there's another part of this step. We need to become willing to make amends. How do we become willing? The use of our sponsors is invaluable in this task.
The Big Book says we should not make amends that will damage other people. But that doesn't mean those people shouldn't be on our list. My opinion is that we talk about each person on the list with our sponsors and other OAs. We decide with their help which ones we really owe amends, we decide if any would hurt someone else and then we decide how to make these amends.
And then we pray for willingness. In a couple of cases, my HP kept putting the guilt in my mind so strongly that only taking care of it would erase it from my mind.
I have a couple of 8th Step stories. The first was a man that I had a relationship with many years previously. I had not thought of him for years and then within a couple of days, memories of him came to me at three different times. Finally I said to my HP "what's this about? Why am I thinking of him?" As soon as I said it, I realized that he needed to go on my 8th Step list. So I made a list of the things I had done that caused me guilt and became willing to make amends. I have no idea where he is -- a reasonable search didn't turn him up. So for today, the end of this story is that I am ready to make amends, but can't unless he comes into my life again.
Another was a business dealing I had with a woman who became very angry with me. I drove by the road to her business several times a week and each time got that feeling in my gut -- something is wrong here. One day there was a detour and I had to go directly past her building, so I said to my HP. OK, I will put her on the list. On closer examination, I found that although we had disagreed, I really did not do anything for which I needed to make amends, and from that point on, I was able to drive past without feeling anxious. It took the willingness to put her on the list and examine it to take away the bad feelings.
There was one time I was dishonest with a business about something I returned. I lied about the way it had been damaged. Every time I used the product, I felt guilt until I had to put it on my list. That one I DID have to make amends for.
Upon self-searching I also found that there was something on my conscience from the time I was a child. I had broken a window in a church near me and not paid for it. Direct amends were also in order for that one.
I like what the AA 12 x 12 ends with:
This step . . is the beginning of the end of isolation from our fellows and God.
STEP EIGHT ~ QUESTIONS
1. Have you felt shame about things in your past?
2. Do you feel guilt about things in your past? Do you see a difference bwteen shame and guilt?
3. Is there something keeping you from making the list of people you have harmed? What is it?
4. Can you separate making the list and getting ready from the 9th Step?
5. Can you see the benefits to yourself from doing these two steps?
6. How have you worked on becoming ready to make the amends?
7. Is your sponsor involved in your 8th Step work? How?
8. Do you need to split your 8th Step list into categories?
Those to whom I could make amends right now
Those to whom I think I could make amends in the future
Those to whom I can't see that I will ever be able to make amends
9. If you've made this list before, has anyone moved from one level to another?
10. Do you have anything additional to share on the 8th Step?
