"""" but the best solution for this type of antenna is to increase the distance between directors....

,,, this is a simulation with 8mm rod.... The constructive dimensions...

,,,hi buddy...!!! ,,, your construction does not work because the adaptation between the coaxial cable and the antenna is not correct...!!!!

,,, and by adding a batwing director the front-to-back ratio is emphasized...

And seeing this, I decided that a rounding of the corners is preferable(radius = 4 mm)...

,,, if the adaptation line is elliptical, a wider frequency band is provided... ,,, constructive details.... CST file,,, batwing elli.cst

,,,and a simulation with only two patches... ,,, with dimensions of transmission line balun Guanella ...

I show you a Guanella 1:1 balun with high choking impedance for most antennas over voltage baluns and 4:1 current baluns,used to adapt the impedance to the antenna above...

Turning a Petra Lite Box home antenna with a 10-meter USB extension cable into a street Internet access point with a 30-meter twisted-pair FTP cable is a couple of trivialities using the AXR-1PoE router, RJ-45 cable gland and the street option for attaching box antennas . Dismantling the elements of the USB extension cord, four holes for the M4 screws, ripping the existing PG-7 hole to 20 mm to tighten the RG-45. ,,,,and this it"s AXR-1Poe router with modem...

", not TUL, I think this antenna is not broadband...!!!

,,,okay Aurel,I"ll try to make a simulation with your wire TV antenna....!!!

,,, correct if you want my drawing above...!!!

And of course look inside. The dimensions of the base reflector 256х287 mm: And on the sides there are plates 28х269 mm. the Distance between them — 244 mm side The overall dimensions of the resonator — 228х268 mm, its width in the middle slightly smaller — 210 mm. The distance between the resonator plate and the reflector 29 mm. Amplifier Board is soldered at a distance of 89 mm from the top edge:

,,, and the results that do not seem too good...!!!

,,,that's it Super flat/thin antenna DELTA Н117А.F-5V...???

and here are the results of the quasi-bowtie antenna... ,,,, by adding a reflector....!!!

,,,,yes, of course, but some dimensions have to be modified...!!!! ,,,, and I think you're right, a 75 ohm coaxial cable should be used and I think I'll make a simulation for this impedance ...!!!

Operating frequency range, 2350÷2650 MHz..

Panel antenna AX-2020P designed for use in set c 3G modems (routers). Antenna type – common-mode strip grating. Recommended for use at the boundaries of the service area, with a very weak and unstable the level of 3G signal and also in cases when it is necessary to use a large amount of cable between the antenna and the modem. Electrical characteristics Operating frequency range, MHz=1900÷2180 Gain, dBi=19-20 The width of the days in H-plane, degrees=6÷18 Days width in E-plane, degrees=16÷18 The sidelobe level, dB, not more=-13 The ratio of forward/back, dB=24 Input impedance, Ohm=50 SWR in the frequency range, not more=1,5 Permissible power watts=10 Polarization=vertical/horizontal/inclined Mechanical characteristics Weight with mount, g=3350 Overall dimensions without mounting, m=0,45х0,45х0,05 Connector=N-female Antenna material=steel, galvanized steel Protective coating=powder polymeric paint Material of protective box=ABS+polycarbonate

,,,yes ,it is for 650---950 MHz...!!!

„, for simplification in construction it can also be so... ,,,or so...

,,, okay, I wish you success ... !!!

RC-Concepts,congratulations....!!!!

,,, and finally, the latest UWB batwing antenna model is optimized...!!!
