I was hoping YOU have the drawings...i never draw any of those antennas...Is on the Petras and others a 3 strip balun from reflector to antenna...
-
Clanon, can you show me this details...
-
Jomy , These BALUN details might be IMPORTANT to know (3-4 feeding STRIPS) do you have a drawing with Dimensions...(Russians use it all the time)

"I don't think I have this file anymore...!!! Maybe only if I bring this topic up again.

post cst
-
I tried to do a simulation for this simple antenna,,,,
-
,,,400 mm length...for 2100MHz to 2600 MHz
-
Two examples of how it's done...
-
Give an example of how to do this. Will it fit the antenna?
-
As you can see...!!!
-
And how to solder it? Adding copper wire?
-
Can I please size the antenna if it's not difficult?
-
is built for bandwidth (i think)...discs won't get the same bandwidth...
-
and as I see on the model, the emitters are not discs but crosses, can I ask you for an explanation about this? I would be very grateful. can I find out the dimensions of this antenna?
-
I think this connector is used on the Tzar Antenna.... N-P245 mufa.cst
-
length=1370mm
-
that is, for a frequency of 2.45GHz, it is not possible to obtain a gain of 20db?(and would it be difficult for you to share the model file, it will help me with my study assignment)

-
LOOOONG TZAR YAGI...950 mm
-
good luck with THAT (Yagis hit a wall around 16dbi) more than 20 is a LOOOONG YAGI...and 200mhz bandwidth conflicts with gain...(A different antenna or a PARABOLIC DISH would get the gain , not the bandwidth)
-
,,, a rim around the reflector,it is not of major importance,so it may be missing...!!!
-
Is soldering suitable instead of welding?
-
It was not possible to attach images. Therefore, I quote. A question for the administrator. Is this option suitable for antennas 1800, 2100? If you make a rim around the reflector.
-
I think such an antenna with such characteristics, besides the fact that it is very long, is even more difficult to obtain. Anyway ,I will try to satisfy your request...!!!
