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 ...
-
I show you a Guanella 1:1 balun with high choking impedance for most antennas over voltage baluns and 4:1 current baluns,used to adapt the impedance to the antenna above...

Turning a Petra Lite Box home antenna with a 10-meter USB extension cable into a street Internet access point with a 30-meter twisted-pair FTP cable is a couple of trivialities using the AXR-1PoE router, RJ-45 cable gland and the street option for attaching box antennas . Dismantling the elements of the USB extension cord, four holes for the M4 screws, ripping the existing PG-7 hole to 20 mm to tighten the RG-45. ,,,,and this it"s AXR-1Poe router with modem...
-
", not TUL, I think this antenna is not broadband...!!!
-
,,,okay Aurel,I"ll try to make a simulation with your wire TV antenna....!!!
-
,,, correct if you want my drawing above...!!!

And of course look inside. The dimensions of the base reflector 256х287 mm: And on the sides there are plates 28х269 mm. the Distance between them — 244 mm side The overall dimensions of the resonator — 228х268 mm, its width in the middle slightly smaller — 210 mm. The distance between the resonator plate and the reflector 29 mm. Amplifier Board is soldered at a distance of 89 mm from the top edge:
