  1. I recently copied this antenna design from the internet and although I'm pleased with its performance, i have my doubts about the original configuration so i have made a change to the driven element. The driven element on the original design appears to be coupled to the rest of the elements - surely this creates a short circuit? so what i have done is isolated the driven element from the boom. what do you think? cheers.
  2. I thought people here would enjoy seeing the progress so far on building a complex 'X-wing' antenna. I'm still testing and figuring it out, but this is looking good so far. I welcome any thoughts you have.
  3. Hello to you; I'm coming here in hopes of learning more about self-built wireless antennas. So far I've watched a great number of Andrew McNeil's videos and have largely decided on this multi-element yagi The issue for me is that I have a philosophy of avoiding money and purchases whenever possible. I build what I need out of found items and what I have nearby. So while I have plenty of copper house wiring (for the elements themselves), some wood and metal for a spine, and a soldering iron -- what I don't have is a metal SMA connector. So my first question is, would it be possible to repurpose a dipole antenna piece for this? Since there are two points which need to be soldered (like an electric outlet) there would need to be two conductive parts on the dipole. I assume that one of the two cylinders could be that part, but I don't know if it's the one on the blue arrow or the one on the red. It does seem possible that this piece could be used for a cantenna by isolating the cylinder from the can itself and I will likely try that with one of these. I thank you in advance for your expertise Aaron
  4. i saw dual-barrel gun today...can yagi work like that? LIKE 2 stacked yagi, but 1 vibrator,1reflector BUT 2 sets of directors? placed side-by-side at 1\4wavelength vibrator should be 2-4 mm closer to first directorS (not like in single yagi) but reflector-vibrator should stay same (29mm)
  5. I can repair split air conditioners, satellite dishes, conduct electrical wiring. I can fix cars, and a lot more that I can Recently, I put amplifiers gsm-3g. Grateful to these my professions, I did not become rich. But, I live in prosperity. In my refrigerator sometimes there are cheese, fish, sausage, and much more. Thanks God! But, recently there was a client asking for a lot of wimax2300-2400. And I, understanding nothing in excess of high frequencies, tried to understand the theory and practice of these antennas. How do I do it - I'll write a little in this thread.
