  1. The influence of the coaxial cable length on the Vee antenna...
  2. 2 PCs F female to SMA male plug straight glodplate TV jack F/F RF connector f - SMA adapter Interface types are Included in RF adapter, such as SMA, TNC, N and BNC, which are available in male, female, plug, Jack, receptacle gender, In 50 Ohm and 75 Ohm impedance and in standard polarity or reverse polarity.
  3. ,,, and yet it looks better .. !!!
  4. ,, bi-circle antenna after a few changes ...
  5. it can and so ..!!!
  6. So it is, it seems ...!!!
  7. and this is your antenna ...
  8. Not, varying the angle of reflection of the reflector, different values of the antenna parameters can be obtained. These are my dimensions...
  9. Instead of this antenna monopoly ... ,,,you can use this ...
  10. ,,,it is advisable to polish the wire over a third of its diameter....
  11. ,,,with other dimensions we got this....
  12. ,,,for pragata.my.id K3TZ on PCB...
  13. FT Mini Arrow v1.1 AIO.pdf.crdownload...don"t work...!!!
  14. At your request, Garry, I made this biloop-antenna for the 1.16GHz frequency... ,,,with the execution drawings... this piece of wire bends with the radius above
  15. from here,,https://www.rcgroups.com/forums/showthread.php?1040837-KFm4-Epp-Swift-Like-(KESL)-32-Wing,,,such as a flying wing of its kind...!!! with these dimensions....
  16. Garry, where can find the drawings on these flying wings? I would like to post them on this topic...!!!
  17. Fine Tuned Inverted Vee Antenna for longer range video transmission.
  18. ,,,this it"s monopole antenna with ground plane radials...!!! ,,,if you want I can do a simulation on the desired frequency...!!! ,,,see this...https://m0ukd.com/static/calculators/Quarter_Wave_Ground_Plane/quarterwave.html 433 MHz
  19. ,,,something like this...??
  20. ,,see above...!!! ,,very wide band antenna..!!
  21. "I think something like that... Frequency of work 48,5-100 MHz 174-230 MHz Gain =9-10 dBi
  22. ... for these frequencies(433MHz,1200MHz), the antennas become much larger, so some miniature antennas should be used in this case...!!!
  23. Beautiful flight...!!!
  24. ,,,my friend, I think it would be interesting to present some flying wings ... what do you say?
