,,,400 mm length...for 2100MHz to 2600 MHz

The 4G LTE MiMO 2x2 Tsar-Pushka VARIUS antenna differs significantly from conventional ribbed-rod "pushka" antennas in its wider frequency band. While conventional antenna guns can only be designed and manufactured for a single frequency band, the Tsar Cannon Varius antenna model works perfectly in the 800 MHz band from 1700 MHz to 2550 MHz. The Tsar Cannon antenna can be used on the following bands: Band 1 (1800 MHz) Band 3 (2100 MHz) Band 40 (2300 MHz) Wi-Fi 2.4 (2400-2500 MHz) The antenna has excellent cross-polarization isolation, which allows the MiMO 2x2 technology to operate as stably as possible. Maximum antenna gain of 11-14 dBi The Tsar Cannon antenna has a pronounced radiation pattern. The antenna can also be used in the 2500-2700 MHz band (Band 7, Band 38), but the gain will be low and the SWR will be high. We recommend using this antenna in these bands only in extreme cases when there are no other options available.

Two examples of how it's done...

As you can see...!!!

I think this connector is used on the Tzar Antenna.... N-P245 mufa.cst

length=1370mm

LOOOONG TZAR YAGI...950 mm

,,, a rim around the reflector,it is not of major importance,so it may be missing...!!!

I think such an antenna with such characteristics, besides the fact that it is very long, is even more difficult to obtain. Anyway ,I will try to satisfy your request...!!!

,,,,prda, your antenna looks like this... ,,,your antenna... ,,,and patch antenna 5 GHz ,10 dBi...

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/ https://repiter.mobi/uk/news/2663755-antena-batving-batwing-5-8-ggc-12-dbi-30-50-vt-dn-5812gr/

I tried to do a simulation for this antenna and it resulted in some miniature dimensions....!!! ,,,and for the 5.8 GHz frequency...

If you solder the shield of the coaxial cable to the ground, it is not recommended.

The dielectric constant of styrofoam (expanded polystyrene) is approximately 1.02–1.04. This low value is due to its low density, which consists of air bubbles (with a dielectric constant close to 1) and the polystyrene material itself. The dielectric constant of solid polystyrene resin, without the air pockets, is higher, ranging from 2.4 to 2.6. For expanded polystyrene (styrofoam): The dielectric constant is approximately 1.02–1.04, which is a very low value due to the high volume of air in the foam. For solid polystyrene resin: The dielectric constant is higher, ranging from 2.4 to 2.6. Factors influencing the value: The dielectric constant is influenced by factors such as density, moisture, temperature, and frequency. Frequency dependence: While the dielectric constant of solid polystyrene is relatively flat up to 1 GHz, the value for the foam is measured in specific ranges, like 100-400 MHz.

This is harder to build...

After so many years I tried to recreate this antenna with the dielectric lens....

,,,2.1---2.5 GHz, is the frequency range quite good...???

,,,does this suit you...??

I don't know if this can help you.....

If I remember correctly, I tried something like this... but I'll try this square bester too, inside of beercan...

,,,there... bester.stl

Clanon, maybe you can optimize this.... bester comercial.cst

I wonder if the antenna elements have concentric copper circles on PCB...???
