and what is the impedance of the antenna output? and VSWR..?
-
"I think with your project there are some problems....
-
,,, welcome to this forum, buddy ...!!!! ,,,for... "how to plot the axial ration VS frequency in CST...?" see this...
-
That's different, BackFire Antenna with dipole...!!! it would be time to close this topic...!!!
-
,,how much it is...?/
-
,,, but that's for 5ghz, 24dbi, diameter = 440mm
-
,,,not "TDJ Parabolic Antenna",this it"s te best patch-yagi antena on the offset parabola...
-
,,,show more about this ....!!!
-
,,,my UFO-Dracula2...
-
"old things",junk
-
But this it"s another" fish food "....!!!!
-
What's that stupid question?
-
maybe it's the best....
-
,,,from where 13dBi..???
-
,,,what is this ,,,?? a toy...?? This is a real antenna....!!!!!
-
Search for and find...!!!
-
-
and Power for what is it?
-
,,,okay,I see, but it has power supply..., do not understand the question, put the feed(POWER) in touch with WAN/LAN
-
,,,maybe with this...
-
I'm not so sure of that...!!

,,,the gain which can be obtained with a parabolic reflector is proportional to the square of the frequency. If this mirror to 2400 MHz can give such as 21 dBi,for 800 MHz,the gain 9 times (9.5 dB) lower than, i.e. about 11.5 dBi ,,,the strengthening of the parabola is G=e * 4 * pi * S / lambda^2, where S is the area of the aperture in m2, lambda is the wavelength in meters, e is the coefficient of the use(e- efficiency aperture reaches 55-65%) ,,,for e=77% => F/D=0,75 where F=focus of parabola : D=diameter of parabola
-
,,,study the parabolic(offset) antenna calculation...!!!!
-
,,,, wrong, MikroTik SXT RB LTE 3-7 antenna is not in the offset disk focus
-
the antenna geometry must be chosen with vswr <1.5
