,,,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...!!!

1. Working frequency: 2.35-2.55GHZ 2. Antenna gain: 10.5dB (typical value) 3. Antenna standing wave ratio: <2 4. Power capacity: 10W 5. Mechanical size: 5×10Cm (without joint) 6. Radiation direction: directional linear polarization 7. Connector type: SMA-K (standard female head, external screw inner hole, customizable)

Harry36,try to put the pictures to be seen..!!!

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...??

,,,hi buddy...!! ,,, can you give constructive details ... ??

Let's make the next copy of the antenna.. Caracteristicas: Conexion: por cable RG-178 a RP-SMA. Frecuencia: 2,4 ~ 2,5 GHz Impedancia: 50 ohmios. Ganancia: 10 dBi a longitud de cable "0" Polarización: Lineal Dimensiones: 100 x 65 x 30 mm Material: cobre (bronce) de 0,5 mm de espesor.

,,, but what do you say about that ... ???

,,, two variants-the first is to choose...!!!

,,,what bucket do you have ... ?? ,,, some dimensions for buckets...

...1 Crossed Dipole Batwing Antenna ,,,2x2 Crossed Dipole Batwings Antena

,,, okay, now I'm getting to work...!!! ,,, you can make something like that...???

,,, of course, I will try to design a batwing antenna around this frequency...!!!

,,, this happens at cross polarization...!!! ,,, but by changing the dimensions a wide band of frequencies can be obtained...!!!

Picture series shows the teardown of this antenna. This particular version has separate 7/16 connectors for connection to the horizontally and vertically polarised antenna. Construction is very solid Deutsche GrÜndlichkeit: stainless steel bolts, silvered connectors, tons of pop rivets to obtain a very rigid construction etc. The Kathrein catalog promises 15 years of maintenance free operation. As can be seen extensive lengths of semi-rigid, or more exact Huber & Suhner Sucoform 141. The cables are connected via soldered-on 'junction boxes'. The white blocks are plastic spacers.

,,, maybe so ... ,,,or so...
