,,,hi buddy...!!! ,,, yes, but anyway you did not rotate the antennas by 45 degrees as I showed you...!!!

Covid-19 ,,, if the angle of 90 degrees is increased , a good uniformity of the frequency bandwidth and impedance of Batwing-Antenna can be obtained... angle=100 degrees ,,,Covid 19-1 angle=111,5 degrees

Different forms of dipole.. ,,, and a simulation of one of them...

,,,named Covid-19,,, after a moment of inspiration, I managed to configure a new Batwing type antenna that provides a wide frequency band and a VSWR factor <1.5... The antenna is made of round cut galvanized sheet, cut triangularly and rounded corners..

,,, something like that ... !!!

,, you're not interested in the Batwing antenna ... ?? ,,, or so it may be...

,,,, hey man, I only posted this as a price comparison...!!!

,,, it's not a bit expensive compared to this one...???

Antennas work and perform their functions, there is a noticeable difference in price, although it should probably be the other way around ! Do not forget that for confident reception of DVB-T2 at a significant distance (60-70 km )from the signal source, it is necessary to raise the antenna from the ground by 12-15 meters, a strong mast + MANDATORY GROUNDING + side lightning protection. Source DVB-T2 Ostankino 10kW — distance 20 km conditionally direct visibility of the floor 12.

,, and how much does cost the SWR meter from Owl-RC ...???

,,,ok,thanks,,,!!! ,,, and SWR-meter can be DIY...???

,,, good job buddy, congratulations...!!!! ,,, please tell me, at what maximum distance can you pilot this drone .. !!!! ,,, and if the SWR meter is built by you...???

The antenna of REMO "WiFi Agent InDoor" is of the directional type. The model running in the 2.4 GHz band is able to provide you with the ability to receive even a weak Wi-Fi signal. You can use the antenna to connect to a remote wireless network. This feature can be useful when using the signal of public access networks. Using an antenna can also be useful in private homes that have a complex configuration: in these conditions, the signal from routers and access points often does not reach remote premises. The data transfer speed can reach 150 Mbit/s. Some technical details...

,,,hi buddy...!!! ,,,,from here...https://bester-ltd.ru/product/antenna/

These are the original dimensions..

Okay Eric, but you want your vibrator in the air or on the PCB...???

Good morning Eric...!!! ,,, you are interested in the yellow model...???

,,, no, 7mm is too much ,,, maybe 4.5mm compared to the copper layer ...!!! ,,, but tell me what PCB you want to use and I will try to help you...!!!

,,,hi buddy...!!! ,,, first of all I tell you that it is not absolutely necessary to present my images in copy ,,, the distance between the reflector and the PCB is chosen to stabilize the impedance of the antenna ,,, the connection of the vibrator to the reflector by screw, influences the impedance of the antenna but it is also possible to remove the electricity ,,, it can also be double-plated PCB, but it must be of good quality

,,,, and these are the results of the simulation but I think that the position of the vibrator must be modified to obtain the maximum operation...

Thanks the user "com666" for transmitting the dimensions of this antenna...

,,,, yes, REMO the manufacturer, also has the circular version of this antenna but with an output impedance of 75 Ohm ,,,and resonator (puller unit)....

I tried to simulate this monopoly antenna and it seems to provide a fairly wide bandwidth..
