I don't understand exactly what you mean...!!!
-
,,,and this works just as well...
-
,,,hi buddy...!! ,,, yes it is possible, but it must be recalculated...!!! ,,,but tell me too, how you get these dimensions (framed in red)...???
-
Most of the parts on these planes are tabbed or slotted for ease of contruction and alignment... ,,,,building airplanes...https://rc.tomhe.net/su-37/

Bester optimized...ensures impedance uniformity over the entire frequency band...!!!! I think that of all those who tried to adapt this antenna, few succeeded...!!!
-
,,,it's not like that...!!!
-
,,,you can also use something like this,for cutting patches...!!!
-
,,,how to build a Bester antenna....
-
,,,show me where you saw...!!!
-
,,,,,,only this is possible... esa.sab
-
,,,the gain it"s aprox 15dBi...you can try whith 75 Ohm cable impedance...!!!
-
,,,another type of omni antenna...
-
,,, an interesting site....http://lea.hamradio.si/~s53mv/cigar/design.html

vertical polarization
-
,,,,yes, but behind the omni antenna, you need a conical,elliptical, paraboloid reflector...!!! ,,,the simplest conical reflector...
-
,,,the offset dish must be placed like this...
-
,,,,,how it looks coax collinear antenna 5dbi ...????
-
,,,it doesn't matter the material...!!!!
-
,,,it doesn't matter the material...but how you weld aluminum...???
-
,,,why...??
-
,,,yes...!!!
-
,,,the length of the coaxial cable must be a multiple of a quarter wavelength multiplied by the shortening factor of the cable(also NVP from English Nominal Velocity of Propagation ) Cable The shortening factor VKF (also NVP from English Nominal Velocity of Propagation ) Open band line=95-99% Belden 9085 (ribbon cable)=80% RG-8X Belden 9258 (coaxial cable)=82% RG-213 CXP213 (coaxial cable)=66%

,,,hi buddy...!!! ,,,why don't you look here...???

12dBi 2.4G WIFI Signal Receive Or Transmit Yagi Directional Antenna Computer from....https://www.aliexpress.com/item/1005004674158845.html,it is made with PVC insulating boom rod. ,,,not everything that flies can be eaten...!!!

,,,an idea of how to build a disk-cone antenna with PCB and wire...!!! https://yandex.ru/video/preview/11458033194622600454
