  1. It can be used for 4G LTE as well as for controlling FPV drones
  2. Copper comes in different grades: M00, M0, M1, M2 and M3. The grade is determined by the purity of the copper content. M1p, M2p and M3p copper contain 0.01% oxygen and 0.04% phosphorus. Copper grades M1, M2 and M3 contain 0.05–0.08% oxygen.
  3. What if I build it using 1 mm M1/M2 copper?
  4. I got my hands on such an antenna, and I can provide the dimensions for copying.
  5. Why? Because it is difficult to make it from a printed circuit board?
  6. I made this anthenna and want to make it in PCB.
  7. Thanks!
  8. Is it possible to say that an antenna designed for 5645 MHz with a narrow frequency band is more efficient than an antenna designed for 5645 MHz with a wider frequency band? Thank you for the answer!
  9. Hi. Can someone explain to me why you make the PCBs of the antennas like in the first photo and not like in the second? I'm new to this and I can't understand this choice.
