BESTER BDM-2 MIMO 4G/LTE ANTENNA, 15-17 DB

[Luke.z 0]

Hi, i'm new to this forum, and i'd like to know which 4G/LTE antenna is the best for My WI-FI modem .
Also, if possible, i'd like to know all the details about the materials used and all the dimensions of the optimal antenna.

Thanks for all the usefull information, and the support!!

,,,this Bester antenna is for 2.4GHz...(to which you can add directors)....!!!!

Thank you very much!!

 Does the 2° plate lateral cuts need to be oriented with a particular angle to the feed?  (In the left image)

And which materials should i use??

[Admin 2427]

,,,yes, the vibrating element must be oriented at 30 degrees, galvanized sheet can be used...!!!

,,,this antenna works well in the 1800 MHz frequency...

Does it work with a 75 ohm cable?

[Admin 2427]

DavidER,,why don't you look at this post on page 3...!!!

,,,для кабеля на 75 Ом разница только в h1 и h2...!!!

You claim that the cable is 75 ohm for a TV. How can I explain what is used for the 1800 antenna?

[DavidER 2]

Then why not 50 ohms?

,,,certain users requested this and I have to comply...!!!

ДэвидЕР, почему бы тебе не посмотреть этот пост на странице 3...!!!

I watched. How many disks can you add to an antenna? Until 12, 16, 20?

[Admin 2427]

,,,after a certain number of disks(15), their number no longer matters, because the gain of the antenna increases insignificantly...!!!

,,, что-то вроде этого было бы...

Will it work on 2 ports with a 75 ohm cable?

[Admin 2427]

,,,yes,but you want 2 ports with a 75 ohm cable for 2600 MHz frequency...???

,,,да,но вам нужны 2 порта с кабелем 75 Ом для частоты 2600 МГц...???

 

Yes.

[DavidER 2]

And how to arrange 2 ports? 90 or 120 degrees?

[Admin 2427]

120 degrees

Дедеве, как бы это было...

Does this antenna operate in the frequency range 1800-2100? Because when I tested the antenna, it picked up frequencies 1800 and 2100.

[DavidER 2]

If you place two antennas in parallel and connect 2 ports independently, will they work well?

,,,yes, it is better that way ,than putting a single antenna with two ports (MiMo)

Greetings again, after trying many more complex and complicated antenna models from the forum, perhaps thinking that they would work better and being scolded by admin jjjjj perhaps for stupid questions..... I tried this antenna and walaaa!!!, I managed a connection stable at 1800mhz, with an acceptable size (I added about 14 elements), easy to build, little air resistance and almost immune to rain, it surprised me.  How could I squeeze a few more db?  perhaps modifying the reflector?

[Admin 2427]

,,, yes, increase the diameter of the reflector (not too much) and increase the number of directors..!!!!

,,after a certain number of directors, the gain does not increase so much..!!!

 

[Edel2020 15]

ok thanks, I've seen this way, is it more efficient?  What size would it be for your antenna?  Would it alter anything else?
