i like to try do such feed for a 1296MHZ, but I'm not sure about the dimensions, colleagues please tell me what would be the dimensions for a model with two reflectors. This one is too short, I modeled in matlab, resonance at 1500MHz (split coaxial balun):

That's my version of this antenna: (BOX completely incidental, should be other size) size 55x38x26cm bottom : 51x34cm

WOW! @Dr. Pepper You got 16dBi !!! I got only 14dBi I cant change angle of the box in Matlab, thats my limitation. I like to try it on 1296MHZ @AdminMay We have other section for 1296MHZ 23cm band antennas?

Thank YOU! I see the qain is smaller than I got, how it will be with 90deg, i belive that is possible to get 14dBi

"What else, what profit can it give." @Harry36 : I am curious with a bi-loop "in the box" I will be able to get more gain than a biquad, smaller in size, or a better shaped beam I don't have the tool to check this, Matlab antenna toolbox has some limitation. box diameters: 40cmx27cmx20cm +/- 1cm

Hi @Admin Could You Please symulate it for a 1296MHZ (23cm ham radio band)? I will try to cut this shape in laser from metal sheet. Thats my idea to add N or SMA connector. Lets fin out, how it will work with comparing to my biquads

in the simulation I achieved 14dBi. This brim is shallower than the simulation assumes, it could be 11.3 dBi. The antenna is very effective. I'm thinking of replacing the quadrates with loops. I'm thinking of a similar implementation as in the attached pictures, not laminate. @Harry36 Thank you for the clarification. With this antenna I am receiving ham radio beacon beacon SR6 LHZ 1296.830 with level -80dBm - distance 111 km, power 1W My aim is to increase the gain of a single biquad. maybe changing the shape or geometry will help. That is my antenna:
