"Exactly....and i don't what is mumbo.jumbo simulation talks means" ....aurel,what do you mean...???
-
Something like that....
-
"""" the situation in which the reflector, the vibrator and the first director are isolated.... """ as you can see, there is no great difference...!!!! The only difference between the presented antennas, is the provision of electrostatic discharge in the case of atmospheric lightning for the antennas without isolating spacers.

Top 3 Best WiFi Signal Strength Meter Apps 1) NetSpot — both a WiFi signal strength visualizer and a WiFi discovery and analysis tool. 2) WiFi Analyzer — WiFi signal strength meter app for computers running the Windows operating system. 3) Wireshark — is the polar opposite of WiFi Analyzer.

,,,,this is the simulation of the antenna with the isolating support rod (to use plastic rod with plastic screws) ....
-
I am not sure about this... but I have to check it....!!!
-
Aurel, the most correct one would be,,,,
-
Vman, try to see this...
-
I think I'm tired, try to read what interest you , on this forum(there are many interesting...)!!!!
-
-
TRY TO DO THIS...!!!
-
No, not this, try to show me something like this...
-
Anyway, please, post a picture with your antenna adapter to the coaxial cable...!!!!
-
,,,okay Ingsun,I'll do that too...!!
-
"""" a very good achievement RC-Concepts,,,,!!!!

As a variant-shaped core of the copper wire insert in an aluminum plate. And to them already to solder. 1) drilling + braking on both sides 2) riveting 3) grinding+drilling ,,,and an antenna built from jar caps...
-
,,, yes, you can use the thickness of 0.3mm...!!! ,,,yes,9mm and 7mm distances between biggest directors very important and critical...!!! ,,, the distances between the antenna elements:7mm,9mm,41mm,36mm,36mm,36mm(these measures do not include the thickness of the material).....!!!!
-
Hi buddy....!!! Here are the results for 3G, 4G antenna...
-
"""" but the best solution for this type of antenna is to increase the distance between directors....
-
,,, this is a simulation with 8mm rod.... The constructive dimensions...
-
,,,hi buddy...!!! ,,, your construction does not work because the adaptation between the coaxial cable and the antenna is not correct...!!!!
-
,,, and by adding a batwing director the front-to-back ratio is emphasized...
-
And seeing this, I decided that a rounding of the corners is preferable(radius = 4 mm)...
-
,,, if the adaptation line is elliptical, a wider frequency band is provided... ,,, constructive details.... CST file,,, batwing elli.cst
-
,,,and a simulation with only two patches...PETRA-12 MIMO BOX ,,, with dimensions of transmission line balun Guanella ...
