depends on the PROVIDER Polarization if it's linear Vertical Horizontal at 90 degrees is ok...(if Circular you lose several DB) ussually is slanted -45 +45 (90) so rotating the feeder slightly you should get a little more or less gain
-
Testing on CST looked like there is not much difference........ In any case thank you for watching, if you can suggest something it's welcome, in any case I upload the CST file for make things easier. FINAL-BESTER-7-5-4-3-HEX.cst

Please explain me, does this affect performance? Should I make the "cuts" on 2nd disk at about 5mm???
-
A disc without CUTS or SLOTS is Linearly Polarized...tho

Here we are again. So, after received my order from Aliexpress, made this Bester antenna based on admin's suggestions and tested on CST. I ordered pre-cutted brass disks in Dia's 70-50-40-30 (70 at 1mm thikness and the other at 0.5mm), some sma's and also some Hex screws at desired length, with distances at 5,7 and 23mm form 1st to 4th disk. Also ordered 2 pc's of LMR400 at 1m each but it was impossible to fit both on router's T9 ports as the distance is short, so added two smaller cables, not sure about results adding them??? Below I attach a link of some photos of construction, testing with speedtest from any device (laptop via ethernet or mobile via wifi) the download speed was about 80-90Mbps, but it differs duRing day probably because in my village there is only one ISP antenna and it seems to be overloaded. Also it looks like even the SINR is not good, speed is not affected, anyway I'm trying to find a solution for this. Last is to make a cover for antenna protection. Link to PHOTOS

,,,an older of My BatWing antenna simulation and geometry...
-
,,,another recovery after my website disappeared with Batwing antennas... https://mungfali.com/post/342A63F41CEBC2976EE4F309272DE4DBA221A7B4/AD2D7AB60606BAFC9913909FD501592B2182FE42

,,,an older idea of mine that was materialized but I can't find the images of this antenna anymore...

Does this suit you...??
-
I need a 7 disc gun with the correct size 2100mhz 75om
-
-
,,,and another version of mine with the Batwing antenna...
-
,,,an older round-batwing antenna that is quite profitable....
-
-
will it be better if so please give me the dimensions for band 40 i want to try it
-
,,,yes,you can only do it with a single antenna with 3-7 elements...!!!
-
so i got this can i use it with the antennas ?
-
i did like so but i got the same result 84 Dbm
-
ahh okay so the feeds should be placed like this okay ill do it now and see the difference
-
PS, MITICHE, I WOULD LIKE TO ASK YOU HOW DO YOU POST THE IMAGE ON THIS FORUM...???
-
It seems that this coaxial cable feeding position is optimal.... ,,,you just have to try and be careful the coaxial cable does not make contact with the ground...!!!
-
what do you mean should i reposition the antennas to 90% one horizontal and one vertical or the feeds of the antennas ?
-
,,,this is how the two antennas should be connected at 90 degrees polarization...
