alex07111971,
but in the last drawing you can explain? what is red?

[alex07111971]

Red - dielectric! Signed on the picture!

I apologize for getting into the discussion like this, but isn't it easier to buy a ready-made solution from the Chinese? Here, for example, I ordered myself this4g lte antenna

Also this antenna used to be liked, and inexpensive! I thought two to buy: rolleyes:
At this time, I think to buy a single MIMO antenna? Only now they are expensive, they can become cheaper in a year ...
Decide on the results!

[mixer88]

Pavlunar108 Here you have a MIMO antenna for the same money.

[alex07111971]

Antenna gain DISH + "BOF 2XXX" depending on the size of the mirror used
0.4 meters 18 dBi
0.55 meters 21 dBi
0.6 meters 22 dBi
0.9 meters 25 dBi
1.2 meters 28 dBi

: thank_you:
From me, two BSs (apparently different operators) are a kilometer away with obstacles, there is no direct visibility, and between these BSs a distance of 500 meters, and a universal solution for me would be to acquire an antenna of not a narrow directivity spectrum but wide, so that both these BSs were available . : rolleyes:
The antennas presented above apparently need to be accurately directed to the BS.

I think that you are wrong! The second tower for the first will be a nuisance! On the contrary, you have to isolate yourself from the second tower! All antennas have one of the main characteristics of the radiation pattern! It shows what angle and with what gain the antenna has! All characteristics of these antennas can see on the site lan23.ru

[Pavlunar108]

Yes you are right, but the directional pattern can be narrow or wide. In this case, I need a wide, and preferably with a wide range of frequencies if possible.

I use LTE-modem huavei E3276 at work and in the country. At work, the signal is very unstable 1 stick, in the country as a rule 1-2. I want to connect an external antenna to the antenna connector. Tell me which antenna is best for me?

[alex07111971]

slopedwhich operator?

[sloped]

alex07111971 @ 10/15/2013, 09:47

sloped which operator?

Yota Ufa

[sloped]

Called eto, said tower address. To the tower 2.1 km. The terrain is flat, residential area, 2-3 storey houses, trees. Now at work shows -88 dbm (1 stick).
For me the most important thing is not to carry a bulky antenna with you to work / from work. That is, he brought a modem to work, connected an external antenna, then went to the cottage, connected a country antenna, etc.

[alex07111971]

slopeda why drag, do two! DBM-1 is small, it's easy!

[sloped]

Can I link and photo?

[alex07111971]

slopedread carefully in this thread! Only three pages! And there is a photo! And links! And the drawing!

[sloped]

What is DBM-1 made of? I can assemble from aluminum construction profiles and fasten on metal rivets, or weld from reinforcement and chermet. Where can I get a cable and connectors for connecting to a modem?

[alex07111971]

slopedThe discs are made from any metal sheet metal (preferably from the one that is soldered), between the discs there is a tube with a diameter of 10 mm (I used the couplings for extending the cables, they are copper) all on a 4 mm pin! And pull on the nuts! I think there are connectors and a cable in Ufa, Google to help! The material is also painted on the drawing! The first disk is thicker than 1.5-2 mm, since the screws must be hidden, nothing should come out between the disks! And the other drives from beer cans!
In post # 41 ready-made antennas by mail, there are also plugs and cable! Good luck!
