  1. ,,,the adaptation lines are not good...!!!
  2. ,,,your antenna doesn't really give good results...
  3. After an idea of Vman... Sector Antenna 2442mhz.cst
  4. I can help you if you don't give me the dimensions,..!!
  5. ,, you can put the dimensions on the dxf drawing..!!
  6. It would be easier for me if you put some dimensions...!!!
  7. Hello, it would be good if you could post some dimensions for this dual band antenna...!!!!
  8. Hello everyone.Here are proven horns for offsets at 5.4 Ghz offset 60cm . horn5,4ghz.cst
  9. DavidER,finally, I managed to complete this antenna,.with 75 0hm impedance(1,95---2,2 GHz)...
  10. ,,, may I try today ... !!!
  11. ,,,why solder a wire, that's where the antennas are connected...!!!
  12. ,,,as you can see, the modem has two plugs for connecting antennas...!!!
  13. ,, is this what it looks like built from PCB...???
  14. ,,,why this difference in the location of the ports...???
  15. Professional panel antenna for modems and routers that support MIMO 4x4 technology. F=1700-4200MHz, CU=9dBi, 4 x N-female connectors, vertical+horizontal polarization, decoupling between channels of more than 25dB. Electrical characteristics of the PETRA-9 MIMO 4x4 antenna Operating frequency range, MHz 1700÷2700 Gain factor, dBi 8,5÷10 Bottom width in the H-plane, deg 59÷82 Bottom width in the E-plane, deg 35÷57 Side lobe level, max -7 dB Decoupling between ports in the operating range, not less than 25 dB Input impedance, Ohms 50 SWR in the operating frequency range at the inputs, max. 1,6 Permissible power, W 10 Slope of polarization of received / emitted waves -45°/+45°(X-pol) Mechanical characteristics Antenna weight, g 820 Bracing mast diameter 20-52mm Operating temperature range -60°C to +80°C Overall dimensions without mounting, m 0, 24x0, 24x0, 1 Permissible wind speed, m / sec 25 Connectors 4 x N-fe male Material of the protective cover Polycarbonate Antenna Material Galvanized steel, brass Mounting material steel / Polycarbonate+ABS
  16. Recently,a new antenna configuration known as Bow Tie Antenna (BTA) or Butterfly Antenna(BFA) are proposed with broadband and high gain properties . The Butterfly Antenna is shaped from four side quadrilateral sheet feed in the vertex. This kind of antenna is defined by quadrilateral the flare angle only.
  17. TL-WN821N is a portable Wi-Fi adapter that can connect via USB to computers and laptops to connect through it with your home router (access point) and safely surf the Internet with speeds up to 300 Mbps. In that situations will it be useful to make a modification,,,
  18. GSM antenna "Razor" is designed to amplify, stabilize the signal and provide high-speed Internet for modems and routers. If the signal in your area is not as good as you would like, the 3G/4G "Razor" GSM antenna will improve the quality of signal reception at a distance of up to 20 km. from the base tower! The operating frequency range is 1700-2200MHz (3G-2100MHz, 4G LTE-1800MHz). The antenna can be installed outdoors, on a pipe, or just on the wall on the side of the base station. If the Internet speed does not suit you, you need to change the antenna mounting location. It attaches quickly and easily. The kit includes step-by-step instructions on how to install the antenna correctly. Technical characteristics of GSM antenna 3G / 4G "Razor" 15 DB: Antenna type Streel, panel Support for standards 3G ,4G (LTE) Gain 15 Db Operating frequency range 1700-2200 MHz Type of polarization Vertical, Horizontal Interface F connector KVS no more than 2,0 Operating temperature range -45 to +60 Seconds Network range Up to 20 km Wave resistance 50 ohms Sizes 225x175x45 mm Weight 445 g ,,,and an attempt to simulate the antenna...
  19. ,,,something to try...
  20. ,,, the frequency of 4.5 GHz is not visible...???
  21. A method to improve the gain of axial-mode helical antenna is proposed. This method involves a parasitical circular metal disk,which is installed on the front of general axial-mode helical antenna and is apart from the helical line. A circular current whose phase lags behind that of helical line current appears,which brings a more concentrated radiation field. Consequently,the antenna gain is improved, Based on the simulation results,an antenna array model fed independently is proposed.This model gives an excellent explanation of the radiation characteristic of helical antenna, Both the simulation and experiment results show that for obtaining the same gain,the antenna length in this new method is only 71% of that in traditional helical antenna.The reduction of antenna length favors the miniaturisation of antenna. In addition, this method has a little effect on the bandwidth of antenna, so it can be widely used in the design of helical antenna element and array.
  22. High gain with wide beamwidth! The Pepperbox antenna from IBCrazy combines a phased array circular polarized antenna system that gives you up to 13dBic of gain, but with a 145 degree wide beam width! All the benefits of ciruclar polarization, but with tons of gain! Should be used in conjunction with RHCP antennas on your transmitters for full performance Pepperbox Specifications: Gain: 13dbic Horizontal Beamwidth: 145 degrees Vertical beamwidth: 55 degrees Bandwidth: 2300-2500MHz
