Hi Do you mind to share your cst file ?
-
Yup it is about polarization of antenna. I think you can Google about how the signal is propagated in your country. The wrong polarization will antuallt cost a big drop to the signal
-
I am using CST studio 2017. other details is shown in the photo
-
Thanks sir, are you using CST 2020 because my version is not compatible. Can you export the model so it can be use in other cst version?
-
I am looking for 60 or 65cm. HI, do you have offset parabolic model?
-
HI, do you have offset parabolic model?
-
We are using CST studio. It is easy to start with
-
Hi admin, can you teach me how to create offset parabolic reflector?
-
In addition, the cable selection also very important, if the system are 50 ohm, better look for 50ohm cable, and select RG8U or LMR400, i think this two cables are the most common cable can be found in market with lowest signal losses. Anyway looking forward for your reply. Hope I can help you as much as I can

Sir may I know which modem you are using(model and number) ? Your country LTE has using which band? Modem has how many port for 4g antenna? What are the input impedance of the modem(50 ohm) ? I think i can give you some oppinion on antenna selection, modem selection, and antenna setup advice. I had imported the TXR185 before: https://images.app.goo.gl/KXE9rHe5aPBtvdN19 The design is not much different from yours. So far the TXR185 performance is just average.
-
Let us simulate in software and see the performance first, there is many others good antenna too.

Hi jeriyant, is the copper tube are insulated? Can you test the connection whether the two copper tube in the dipole is shorted? The structure look weird
-
Hi, I got installed the antenna you shown before. The results are not satisfying. If you would like to use yagi antenna better looks for LPDA (700-2700Mhz). If you are looking for high gain and wideband antenna, better look for parabolic antenna with feedhorn. You are an installer or antenna designer?
-
Hi Jervant, where you come from?
-
The results they shown are also bad. Swr 2.1 at 1.7Ghz... Please take your time to read my previous results and clanon simulation results...
-
This results from seller right? Don't misleads by the seller. I see, but the 125ohm cable is half-wave length. May be you can simulate the result in 125 ohm?
-
Thanks COM666 and admin for sharing !!! May I know what material is used?
-
Interesting, any update from com666? Or any link?
-
"Additionally, you need to solder or rivet the cables from the same material with a size of 34x14mm. The antenna uses two flat square screens: Lower 220x220, above 95x95." Hi, May I know what is the distances between the two flat square screens and driven element? and where is the feeding point? Besides, "5,5x9" in this figure, is this means 5x9mm with 5mm thickness?
-
Anyone had tested this SWR and gain? Thinking to make a dual polarized Bester feed out of this.
-
I see, but the 125ohm cable is half-wave length. May be you can simulate the result in 125 ohm? Any ways to open 2020 file in 2017 version?
-
Hi can you gv use the material and dimensions? Regards
-
Why 300 ohm is used? the cable is 50 ohm, and I am using 50ohm tested it out
-
I think the impedance match cable are half-wave length without shielding (not sure how many ohm, but I suppose is 125 ohm)
-
Hi Clanon, the cst file had some problem. Anyone can provide me the cast file?
