,,, by the way, maybe something like that could be used as crossed dipole...
-
,,,from Sl4va...
-
,,, maybe yes, but you need other distances between the biquad antenna..!!!
-
,,, then try to transposes this type of antenna on the frequency range 1.7-2.7 GHz...!!!
-
,,,a Bester Antenna after Harry36...
-
,,, and these dimensions are important...
-
,,,a fake batwing antenna 1700-2700, 8.7-9.7 dBi @ 50 Ohm from Yurii Pylypenko (ypylypenko) wrote... ,,, and here are my results ...
-
,,, another situation would be if SMA connectors were attached to the REFLECT0R...!!!
-
,,,only if you give me all the dimensions on the antenna....!!!

Harry36-user,he meant other batwings, not even batwings, but Sputnik V. Sputnik V,, put in a bucket... ,,IMAGINE...

,,,checcoanz,there is not much difference, post the antenna dimensions...!!! ,,,this it"s online Yagi Uda Antenna Calculator...??? https://www.changpuak.ch/electronics/yagi_uda_antenna_DL6WU.php
-
,,, what does NEMO mean ... ?? ,,,maybe MiMo(Multiple Input Multiple Output - multiple wireless connections technology)....!!!
-
,,,, it is observed that in the HFSS Software , Phi=0deg ; Theta=0deg...!!!
-
,,, after replacing the connector, place the ALFA AWUS1900 router next to the antenna....

-
I hope it is understood...!!!

Hentenna 2,1 GHz The original Hentenna as a special kind of a single loop was described first in the 1970ies by Japanese Hams, an English article by JF6DEA/KE1EO about the Antenna ("The Hentenna – The Japanese 'Miracle' Wire") was in the QST 1982 and in the ARRL-Antenna- Compendium, Vol. 5. The basic function of the Hentenna structure is the 1,50-λ-Extended-Quad. This antenna with the figure of an "Oblong" has a gain of 3,6 dBd, but a feedpoint impedance of 73 + j 470 Ω. The Hentenna has nearly the same gain, but a clever feeding with an impedance at XX of 50-70 +/- j 0 Ω . https://www.qsl.net/dk7zb/Quadlong/Hentenna.htm

,,,how to put a dimension on the drawing...
-
,,,it is a very good antenna but it should have a wider bandwidth for the 50 Ohm impedance...!!!!
-
,,,yes,it"s okay...!!! ,,,this is you...??
