  1. 1296MHz, previous tests have shown that the antenna also works on the higher bands. I will take two on the VNA and do an S12 between them, then we will know what it looks like. 6xbiqod project has name "MATHYLDE"
  2. Balun has also possibilites be a filter, I wants to do it this way. (it is possible that in the middle of the gap there should be a short circuit to ground on one side)
  3. a)New aproach, converting biquad to biloop, not tested yet quick and careless soldering b)Four biqads for array, eventually there will be six (I have 1:6 powe combiner, thats why six)
  4. thats ~20dBi 920mmx740mm 1296MHz, adequat Yagi will have 4m boom other pictures: https://www.wifi-antennas.com/topic/102-simple-dipole-antenna/?page=2#comment-20589 thats good?
  5. 920 cm pacyfic grid atenna with dipole (with coaxial splited balun and one reflector) wil gove You 19-22dBi, adequat Yagi will be 2m long and and should be carried out with great precision (+/- 0.1mm) add: thats the solution from Slovakia
  6. Solution rarely used, reduces sidelobs, separates from interfering signals, should not affect VSWR, may narrow main beam. Do you use or have seen this?
  7. @Admin {,,,this construction is a bit wrong, mcNeill doesn't really do good things...!!!} McNeil, He performs titanic antsy work in making phantoms, but do not fully understand it, for example, phase shifters are called load coil, and so on and so on... {,,,on this forum there is such a dipole in the correct construction...!!!!} HAMs do not know it, I have not yet seen any HAMs construction with the use of this type of matcher/balun. Most popular is this one: This is material for a separate topic, LTE/Wifi antennas rarely have a balun.
  8. Thank You, colecting materials ongoing.
  9. @Admin This is amazing, this ring makes no obfuscation effect. The feed on the 1296MHz is usually large, and here it works as in an ofset antenna. I have not seen such a design before. BTW, Are You doing EME?
  10. @Admin in my opinion, this antenna can be more efficient than a biquad, I would be happy to make such an antenna for 1296Mhz if you are willing to simulate and provide dimensions. I will compare with biquod made in same technic.
  11. Only few types of the antennas dont need a impedance adapters. The others will have a high loss. Do they have good results without this? The results will be adequate for the price.
  12. Yagi

    Need more than 17dBi? You have to build antenna 10*Lambda boom, You nedd 20dBi than yo have to use Yagi with 20*lambda boom lenght, or try grid or parabola 10*lambda radius will give aprox. 30dBi
  13. Yagi

    @Jeriyant: What is the impedance and did you use a balun?
