  1. For the manufacture of this antenna, dimensions are needed
  2. CM 4251 original.
  3. Dear admin. Antenna Kovachev did not pass our simulation! Should opportunity fill this gap? The calculation was at 730 MHz.
  4. Jomy, what do you think about the second option???
  5. A masterpiece of antenna engineering
  6. Unfortunately, to this miracle, I do not have sizes
  7. Well, here's an option!
  8. What can you say about this commercial antenna???
  9. And the racks are all metal!
  10. Yes, very interesting! I have never seen such a construct.
  11. Thanks, it's really good now!
  12. The antenna was made for a friend living in the countryside. The repeater is 38 km away. The signal level is 90-95.
  13. Admin, please remove the extra photo. Load error
  14. The antenna design developed by the amateur radio operator V. Kovachev was first published in the Bulgarian magazine "Young Designer" No. 8 in 1992. As it turned out, it is also well suited for receiving DVB-T2 digital TV signals. Unfortunately, this antenna is not simple. Making it requires more time and materials than anything we've considered before. However, according to the author, it has a noticeably higher gain than the three-element Sotnikov antenna (triple square). https://antenna-dvb-t2.info/antenna_dlya_dvb-t2_8.php
  15. Your batwing is good! But I do not have enough sheet Al, can I shift up to 730? Why should I cover the entire range! Sizes will be smaller.
