,,,model... 917 x 720 welded iron bars (Pacific Grid) 917mmx720mm and 150mm deep f/d = 0.38 grid parabola.cst

,,,,for 50 Ohm... ,,,,next 75 Ohm ,,,technical details... ,,,to change the impedance the power pin diameter(d0) must be changed...!!! The SMA plug remains the same, 50 Ohm impedance, only the coaxial cable is 75 Ohm.

FPV batwing antenna 5.8 GHz 12dB 30° WavLink Batwing 5.8 GHz SMA, for quadrocopters and aircraft models-will allow you to transmit a radio signal wirelessly, more stably and over a longer distance. The presented directional antenna operates at a total frequency of 5.8 GHz and is mainly used for quadrocopters and aircraft modeling, in order to increase the signal transmission range. A special feature of the model is the high gain, wide bandwidth, collapsible design, good housing materials and a popular connection connector. The antenna is one of the best FPV antennas in its price range, as it has a good gain factor. The gain of this antenna is 12 dB, which is enough for most tasks. The antenna can be used to stabilize the signal and display the image accordingly. Most often, this antenna is used to transmit a wireless signal in aircraft modeling, and it can be used both on transmitters and on wireless receivers. The antenna has a simple design and a high gain, so the engineers of our store conducted a special test. We conducted the test with a quadrocopter and a 400 MW 5.8 GHz transmitter, as well as FPV goggles. In the first test, omnidirectional clover-type antennas were connected to the devices, while the video signal transmission range was about 150 meters. In the second test, the Batwing antenna attached to the boom was connected to the FPV glasses, while the video signal range was about 5500 meters. https://gadgets-world.com/fpv-antenna-batvynh-5.8-hhts-12db-30-wavlink-batwing-5.8ghz-sma-dlia-kvadrokopterov-y-avyamodelei/

,,,this must be it...!!!

,,,let it be a sketch....

",,,such a yagi antenna can also be attached to the focus of a parabola.... The 8x8 boom is made of insulating material....

,,,for which antenna...??

,,,no...

Lunokhod-1 and its antennas! Is the antenna a cannon or a ribbed rod? In fact, this is an antenna complex! Ribbed-rod guiding director system with an active element in the form of a spiral axial radiation antenna! Do you want a good 4G LTE MIMO antenna "like Lunokhod-1" for your dacha?

Petra 9-simulation and dimensions...

Do you mean 1 mm, not 10 mm?

This antenna is not good enough... 3.52ghz.cst

,,,yes..
