  2. Dear fellow friend, I got in my possession an outdoor AP/Bridge model WAP-1001 by LevelOne. I took some pictures and measurement so I can share in this forum. Maybe somebody has an interest to replicate and try this flat panel directional antenna. The only information I know about the antenna is it gain is 12dbi (see the brochure at http://download.level1.com/level1/datasheet/WAP-1001.pdf). Maybe somebody who has information please share... dimension.pdf
  3. can I get dimensional details of this model sir? thanks
  4. yagi

    with the label number model etc...it should have it printed on the sleeve...(eg. RGxx)
  5. they INTERACT for the WORSE ! without simulation ...hard to know...
  6. yagi

    ,,, most of the antennas on this forum are for 50 Ohm coaxial cable adaptation...!!
  7. yagi

    What type of coax cable is supposed to be used? And does it matter if it's 50 or 75 ohms? If it does matter, is there a way to check any coax cable to tell how many ohms it is? Thank you!
  8. Hi, what would happen to the antenna at batwing 2.4 if the size of the reflector make 78h130mm ? I would like to insert 5.8 and 2.4 antennas into one case .

  11. ,,, this antenna is not very good, after resizing I got this...
  12. Manufacturer: Delta Satellite Model: Delta MIMO 20 LTE Band, MHz: 2500-2700 Gain factor, dB 2*20 Vertical / Horizontal polarization VSWR less than 1.5 Connector 2 n connectors (Female) Operating conditions -40 +80 protection against moisture and dust IP 54 Overall dimensions 370*370*25 Weight, kg 2.0 Additional information: Delta 4G-20 (MIMO LTE) antenna) Powerful 2x20 dB, two-polarization MIMO (vertical and horizontal polarization), directed 20°X20°, all-weather IP54 antenna on the range of 2.5-2.7 GHz 2600 LTE (Band 7, FDD 2600) is designed to work as part of modems, routers, routers, LTE-4G access points. Provides maximum connection speed and stable operation in 4G networks for Yota, MegaFon, MTS, Beeline, Tele2 operators in conditions of uncertain signal reception. The 4G MIMO antenna is connected to a modem or router via cable assemblies and allows the antenna to operate on a 4G LTE network.

  14. Arif4050,,, this simulation is older and I no longer have the file ... !!!
  15. How many degrees is it in angle?

  18. Thanks Admin but I didn't find the answer i wanted. I try to explain better: since my design is very large, I'm using field sources and when I use field sources I have the F-parameters. I don't get them, are they like S-parameters? I just need to quantify the antenna to antenna coupling
  19. Yup it is about polarization of antenna. I think you can Google about how the signal is propagated in your country. The wrong polarization will antuallt cost a big drop to the signal
  20. metal THICKNESS and DISTANCES...that's all of course SHAPES are of the utmost importance ... every time you PUT a discrete port between two metals on ANY PLACE ...CST would tell you the impedance THERE...
  21. That is called POLARIZATION both RX and TX should have the SAME (type of antenna) (linear) Vertical , Horizontal , CIRCULAR RH LH (used a lot on FM , it gets inside moving cars) , ELIPTICAL . you could get 3db more of signal just by moving the antena 90 degrees...
  22. Ukamurubasu,see this...
  23. Yeah but one antenna has 2 discret port (1 and 2) and the other has 2 discrete ports (3 and 4). I need the coupling between [1,0]+[2,90] and [3,0]+[3,90]. I hope I was clear
  24. Very interesting topic According my own experiences, the Vertical yagi is better for SpE but 3 years ago during an opening with the Vertical dipole I heard Spanish and Algerian stations, but when switched to my Horizontal dipole, British stations are popped up on the same frequencies. Example: on 88.1 with the V. I heard Batna FM with RDS, but when switched to H. BBC R2 RDS appeared.
  25. Where can you get a 25K audio taper pot for the mid control, other than Alpha? Cant seem to find one in CTS, and CGEs offerings are diminished as well. Thanks
  26. That is true, but I do not know how. Nor do I know how to determine what the impedance of an antenna currently is. This information is kept secret?
  27. discrete ports are the probes i'm talking about...coupling is directly calculated every time you use more than one port
  28. Where do I put the probes?
  29. 20dbi...hard to swallow... 16...17 ...maybe
