Toole ... that's what I have for now, I'll keep looking. The vibrator that sends you as a test is from the Antenna PF5000 and this balum that I had not seen before, but of this if I have no more details

Ahhh wait I found something....the reflector is in the image 60 degrees and the directors is 6.70 degrees

Too bad... I owe you this, it's what I have on hand, maybe you want to try other types of vibrators, I've seen this one in similar models

Here you have it...

Greetings group... I was given the schematic of an antenna that they say is the best in Europe at the moment, but I don't know what impedance this type of dipole has and if it will be as good as they say... could it be modeled and find out if it is as good?

ok thanks, I've seen this way, is it more efficient? What size would it be for your antenna? Would it alter anything else?

Greetings again, after trying many more complex and complicated antenna models from the forum, perhaps thinking that they would work better and being scolded by admin jjjjj perhaps for stupid questions..... I tried this antenna and walaaa!!!, I managed a connection stable at 1800mhz, with an acceptable size (I added about 14 elements), easy to build, little air resistance and almost immune to rain, it surprised me. How could I squeeze a few more db? perhaps modifying the reflector?

Thank you very much, does the height of the patch to the reflector remain the same? If I wanted a 75 ohm impedance, what would I change?

Could it be tested for 1800mhz? I need those 15db

I think I will continue trying with the Yagi....?? 920cm pacyfic grid atenna with dipole feed (with coaxial splited balun and one reflector) will give You 19-22dBi, adequat Yagi will be 2m long and and should be carried out with great precision (+/- 0.1mm)

It's a shame, it's very simple...and yes, they are right...but what can I do? I live in a region with a lot of air and there is no signal below 5 meters. I cannot raise such a large dish to more than 10 meters without having to invest a lot in a good mast. What options would there be?

Clanón... can you help me with something like this for 1800 mhz, I thought about making the Yagi Extreme lll ...but no one has simulated it or confirmed the gain and how good it is

So...can we add directors? Would it work as a yagi?

It really looks simple....what design to do to get closer to 20db at about 20 km in band 3 1800 MHz?
