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

40 posts in this topic

4G antenna BDM-2 is a wave channel with crack initiation, and the delay line is made of sequentially installed disk elements.
Compared to the classical antenna BDM , new directional antenna BDM-2 is:
More gain;
Improved radiation pattern;
More stable operating parameters;
Greater reliability;
Superior mechanical characteristics.
Due to the small weight, a small sail and streamlined shapes, the antenna BDM-2 can be used in almost any climatic conditions. And corrosion-resistant materials of the antenna will ensure a long maintenance-free operation even in the marine climate.

Specifications 4G/LTE antenna BDM-2:
Antenna type    Directed
Beam width H/V °    20/20 
Frequency range, MHz    2600 MHz
Polarization    Linear orthogonal
Gain, dBi    15-17 DBi depending on frequency of execution
The CWS in RAB. the frequency range, not more    1.5
Max. input power,W    50
The weight of the antenna package, gr.    910
Input impedance, Ohm    50
Overall dimensions, mm    Ф90 x 500
The operating temperature range, °C    -40 .. +60
Performance    All-weather, all -
Connector (on the case)    N-female x2

I am looking for a MIMO irradiator for 4g b3 (1710-1880). I found this option, but Yurik says that this antenna has poor port isolation. Can you check it out?

There are not all sizes.

Yes, it is...!!!

Have you tried to optimize it?

Привет я хочу, чтобы разработать эту антенну, в чем разница между 1800 и 2600, предмет частоты событие, которое я просто не могу решить с помощью моих собственных средств? 

Я была бы признателен, если бы вы ответили. 

 

Hi, I want to develop this antenna, what is the difference between 1800 and 2600, the subject of a frequency event, which I simply cannot solve using my own means?

I would appreciate it if you answered.

Hi Mr. Admin I will ask you to help me for this I need a disc-making antenna for my 4g signal 

I made one based on the shares here, but I didn't get the speed I wanted.

Is it possible to build BDM-2 on 4mm steel boom? Does boom size affect the frequency?

I intend to use it indoors only since router is too far away. 
I have 1mm aluminum plate and 0.5mm copper plate 100x300mm 

Or should I built lower gain antenna for indoors use? Cell tower is approx 550m away, one building in between

,,, there is not much difference between the two boom diameters(4mm or 8mm), although preferably it would be a diameter of 10(15) mm made of threaded screw and pipe and patches of galvanized sheet with a thickness of 0.5-1mm....!!!

,,,,increasing the boom diameter ensures a wider frequency band...!!!

Hi Admin,

I am looking for a 70 ohms version for this antenna, since we don't have access for a 50 ohms Cable here in our country.
Or can I use 70 ohms RG6 for this project?

Hi Admin, 

Actually I just wanted to reach the tower that is 10km from my area. I have an LPDA antenna but I believe it didn't reach the tower.
I will be connecting this antenna to a signal booster.

Perhaps a good design for Band 3 \ LTE 4g 1800 will do that will reach 10-15km. Honestly I don't care about how many elements, all I care is to have a signal. :D 
Any suggestions?

,,, for a distance of 10 km, you need a parabolic offset dish...

Hi Admin,

This is great, But we don't have dish like this in our area, I mean no one sells this here.

Question.

If I don't have a disk, and I will increase the elements, Will it reach to a point of 10 KM?


I saw one of your simulations for 1800 Mhz, will this works by using 70 ohms RG6 ? Most of the people here talks 50 ohms I am so worried I don't have the materials to used.

I plan to create this one with ( 70 ohms RG6 - Threaded Rod 6mm - nuts - Galvanize Iron (like the one used for roofs.))

,,, if you don't have obstacles in the direction of Base Station, it might work(but I don't think so)..!!!
