The dimensions in yellow are for the 2300 MHz frequency...
-
,,, something like that, you can never say(3.5 x 3.5 = 12 (dbi)).. !!!!
-
,,,but anyway, I don't think that's the reality.... omni800-2600.cst
-
,,, yes, I think this topic was discussed on a forum...offset helicoidal parabolic antenna....radio vorticity:
-
I don't have these dimensions..maybe only by approximation ....!!!
-
,,, the vibrators are placed on an insulating plate or insulating tube PVC spaced from the reflector ... there are many solutions ... !!! The 50 Ohm impedance coaxial cable connects directly to the feed points.
-
Speak in English...!!!
-
,,, here you can find what interests you ... !!!
-
-
,, these would be the dimensions ... PCB material double plated FR4 #0.5mm
-
for which antenna ... ??? where is Harry36's original drawing ... ???
-
,,, there are a lot of antennas on this forum ... choose one ... !!!
-
Samir, only English is spoken here ... !!! ,,,for 75 ohm cable the only difference is h1 and h2...!!!
-
,,,what does the antenna look like ... ???
-
,,, yes, but I think the reflector is a kind of satellite dish...!!!
-
These are the dimensions for the 2.4GHz Bester antenna
-
Samir,, wait until I do a simulation for the 75 Ohm coaxial cable..!!!
-
,,.it is still possible(2,4 GHz) ...!!!
-
I think so....!!! 4.bmp
-
,,, for coaxial cable with impedance of 75 Ohm another distance between reflector and vibrator is needed...!!!
-
MiMo Bester after optimization.... ,,, constructive details ...
-
,,, a simpler and improved version... ,,,notched vibrator and supplied directly with coaxial cable...!!!
-
-
,,, yes, that's about it...
