  1. yagi

    thickness of material > 2 mm ...why ?? should be 0.5-1mm
  2. Hello my friend, I do not have the dimensions of these antennas, but I will try to simulate something similar..!!! You have the dimensions at this antenna...??
  3. Yes, but I think it's better my UFO-Dracula...
  4. Heart of the antenna is low noise digital amplifier, high-frequency chip Kzt67. Philips c gain 22 dB.
  5. Antenna CIFRA-30 with built-in amplifier is used for receiving and strengthening of TV signals with DVB-T, DVB-T2 and analog TV UHF band. The type of the antenna-resonator. Recommended for use at distances up to 20-30 km from a TV repeater. The antenna gain, dBi 7.5-9.5 Gain built-in amplifier, dB19÷22
  6. ,,,41,6mm...!!! (48,7+34,5)/2 = 41,6mm-1,5mm=40,1
  7. Can be made of a pcb board and a metal reflector
  8. ", that's your antenna ... !!!
  9. Я не знаю, я должен учиться ... !!!
  10. And how do you want to do this?
  11. I think this one...
  12. ,,,yes dear tcl32...!!!
  13. I wrote to you above that the antenna has a 240-300 ohm impedance, so you need to adapt for a 75 ohm cable. ,,,something like that...
  14. The impedance is highly dependent on the construction details. In general, you can expect 100-400 ohms of impedance. The nominal impedance is generally considered to be 400 ohms.
  15. 1) 240---300 Ohm 2) ,,,no...!!!
  16. ,,,the antenna according to E. Spindler....470 - 790 MHz
  17. And yet, this antenna is not really good ...
  18. No, the drawing is very good...!!!! I'm going to make a simulation on this antenna.
  19. ,,, good, put the dimensions if you can ... !!!
  20. StationBox 5 GHz 20 dBi SISO....
  21. ,,,for another form of antenna ... ???
  22. The SMA port has this configuration...??? and this is for simulation... SMA mic.cst
