Excellent ... now if I'm going to try JJJJ ... only the measures of the patches are missing on the edge of the reflector. Could it be covered with a specific plastic or can it be anyone? A question ... The square bester D1 would be 99 or 69?
-
Sorry, but the D1 measurements were missing.
-
Yes.. it looks good, I could try... give me more construction details
-
Thanks friend... I just can't stand making more circles anymore... it's easier and much better to test this way. Can you use a central support wider than 6 mm?
-
Hello admin... what is the best option you have with square elements for 1800 MHz? How many elements should I have to reach 14 db or 15 db?
-
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
