thanks, finally after some attempts it worked perfectly vswr <1.5, forgot to take photos

@clanon thanks yes with that filter added vswr was good, is there a filter for 5.8 too? To make 5.8 at least workable

After 10 failed attempts I think deviding was not good idea, so friends just use antenna as it is, hope above information will be useful to someone thanks

Yes it become just ordinary service recently, can you give some advices how to change lines?

I have at top corners, small square, can you help with that and check on simulation software?

You mean lines connecting elements?

Which limes?

I tried like this but still fail

Vswr is good why you think it is not good? I cut right next to solder pin and it showed good results like peak 1.8 at 2.3-2.5ghz with a good cable, but 5.8 didn't work yet

okay i will get dimensions asap

Most interesting part is that original factory antenna's vswr showing sometimes good vswr, sometimes bad depending on analyzer-antenna cable jumper's position, like if i bend it's good, i'm using jdsu celladvisor

I tried both options vswr still high, i placed feed1 a bit higher, to upper square though, it was originally designed with N type connector but i replaced it with cable, should it effect? i will try check sizes and send

have you seen dxf it's correct dimensions

here is the dxf file https://disk.yandex.ru/d/HBfm2j3BfYz5qA spacers are made of plastic, bottom 4mm, top 8mm

Hi! I had 2.4Ghz & 5-5.8GHz 14dbi panel antenna, I'm wondering if i want to have signle band antenna like only for 2.4Ghz and only 5.8GHz antenna - can i cut somewhere in middle and still have good vswr? Antenna made of galvanized steel, here is the drawings of it? I tried to cut right next to the soldering pin and assembled antenna but vswr was around 1.8-2.2 while factory vswr is 1.3-1.5 any help is appreciated thanks
