please....

I like it Admin, what would be the panel measurements for LTE 1800 75 ohm?

Could there be a version for 1800?

Thank you very much, Discarded Project

I could have a balance like that, simple and practical

Yes I know, it should be like that, but sometimes they surprise me, is this the case?

How much loss will the published model have?

I see that in Asia it is very common to use antennas without impedance adapters and that they give good results, how is this possible?

Anyway friends, what conclusion did you come to with the modeling of this antenna, is it that good?

Hello friends, I found this antenna on my friend's channel https://www.youtube.com/@mul_onochannel1569, I would like someone to model this antenna to know how effective it is and if it could be optimized, it will also work with rods and a reflector. mesh? It is supposed to be for the 1800 mhz frequency.

thanks

Ok sorry if I'm clumsy searching, but this forum is huge and I've been searching for hours, I see that you offered to optimize this model and if I wanted to, I haven't seen other models this simple and powerful, yes I have seen others but with very complex balance lines Sorry again if I got into a very old topic, can you help me?

Although I don't have its measurements either, I'm looking for powerful and easy-to-make antennas only for 1800 MHz

Yes... that's what I'm looking for, a lot of gain and easy to do, do you have the measurements of that antenna for 1800 and optimized is it better than this one?

Let's go group, only Wi-Fi is not lived jjjj... the best thing I've found profit size ratio!!... pity not having the measurements

The bad thing about this antenna is the F / R, how could it be improved?

We could take the design of the active element used by Brian Beezley Author of the Site http://ham-radio.com/k6sti/index.html in your Metric Yagis to improve it?

Can someone model it and share the changes?

Here are the .maa file

UKW 14 Elemente, DDR-Ausführung.maa

has a great profit for its size, especially after being modified by the friend Peter Körner ....

Hello greetings to all ... continued with the subject to not let it cool I found this antenna produced only in the old GRANIA Germany in the 70s and 80s, great gain but very badly distributed throughout the bandwidth we use today (88-108) in those times and in that F / r.

Please someone who uploads the scheme of a good RF amplifier for this band that is well tested

Please upload all the data, I mean gain according to frequency, f / b, etc.

I'm going to try your suggestion, I like it to be 75 ohm and especially the size

You're right, it's big, it was just to test if it could be made smaller and keep the gain high, maybe with a bigger reflector, you are the specialist, thank you very much

simulate this ... but try to give a more contained size and run the frequency towards 98 Mhz and not the 105 Mhz in which the band is centered in this antenna

If that works it would be very good, it has a good size, how did the simulation turn out?

excellent, this is what i mean
