  1. Heart of the antenna is low noise digital amplifier, high-frequency chip Kzt67. Philips c gain 22 dB.
  2. 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.
  3. ,,,41,6mm...!!! (48,7+34,5)/2 = 41,6mm
  4. ", that's your antenna ... !!!
  5. Я не знаю, я должен учиться ... !!!
  6. And how do you want to do this?
  7. I think this one...
  8. ,,,yes dear tcl32...!!!
  9. 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...
  10. 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.
  11. 1) 240---300 Ohm 2) ,,,no...!!!
  12. ,,,the antenna according to E. Spindler....470 - 790 MHz
  13. And yet, this antenna is not really good ...
  14. No, the drawing is very good...!!!! I'm going to make a simulation on this antenna.
