,,,this is very broadband and is not possible...!!! ,,,maybe 2 antennas with the respective frequencies...!!!

,,, narrow band ... how narrow ... ??? ,,, for what frequency ... ???

,,, maybe these posts will help you....!!! https://yandex.ru/video/preview/?filmId=10434698562256898701&p=1&text=3G+4G+Olkhon+irradiator+antenna&where=all Type:parabolic (offset) 3G / 4G antenna with mesh reflector Type of reflector:mesh (steel wire Ø3 mm) Destination:to enhance the level and stability of 3G / 4G (LTE) signal, as well as increase the speed of mobile Internet Terms of use:in indirect visibility of the base station MIMO 2x2 support:+ Operating frequency range:1800-2100 MHz Supported communication standards:LTE-1800, UMTS-2100 Gain:2х 30 dBi Electrical circuit:shorted Input impedance:75 Om Connection connectors:2х F-female SWR in the operating frequency range:no more than 1.5 Power capability:10 W Suppression of parasitic polarization:-25 dB Polarization:type X (horizontal and vertical) Lightning protection:integrated Supported communication operators:Vodafone, Kyivstar and Lifecell Maximum distance from the base station:up to 25 km The stated level of mobile Internet speed enhancement:up to 250% of the initial value Mounting the antenna:on the bracket or pipe Change the polarization of the:360° Wind load:5 kg / m2 Operating temperature range:from -60°C to +40°C Degree of protection from moisture and dust:IP68 Overall dimensions: - reflector:50x60 cm (netted) - irradiator:250x125x125 mm - weight in the Assembly:1.6 kg

,,,yes...!!! ,,, somewhere on this site there is such an antenna...!!!

Of course....!!

,,, an improvement of the Batwing antenna with dielectric lens...

I think you're talking about the yagi-antenna with wire elements..!!!

,,, coaxial cable with 50 Ohm impedance and a box with the dimensions below for MiMo Batwing antennas...

In fact, nothing new has come up, just connected the methods of powering the two ports, the outcome is greater than -20 dB throughout the band, wide band SWR. The antenna is recommended to be used in the focus of a parabolic offset disk.

,, please if you can tell me if you can make a splitter for 4 batwing or 4 patches antenna with 75(100) ohms each...

,,, something like that ... for cross polarization...

,,,metal, M3 screw...!!!!

,,, if you add a dielectric lens (polystyrene foam), you can increase the gain in directivity ...

,,, it was appropriate to make the rectification required by optimizing the Batwing antenna for 5GHz band frequency.... ,,, and the practical realization of antennas ...

,,, you can try this with ALFA AWUS036NH....

,,, it can be 9 dBi...!!! ,,,but try to rotate the antenna 45 degrees horizontally and change the position in different places...!!!

The antenna (TP-link ANT2409A),has only 6 dBi gain in directivity, try a stronger antenna made by you .. !!!

,,, the material used for antennas does not have much influence...!!! ,,,usually used galvanized sheet, covered with Rilsan (or a coat of paint)...!!!

,,, it's good, and the other port ... ??? ,,, put the simulation ... !!!

,,, sorry, but I don't know ... !!!

,,, I don't know how to do it, I posted something like that before, so there are three -four posts with Antena Nitsa .. !!!

It would be good if this simple version were tested as well....!!!

,,,no,I think that the director's clearance, it"s not taken into account in the model when calculating...!!!

,,,thanks swarg_eu,can you put these dimensions, please ... !!!
