Best Antenna for LTE Bands (1800, 2100, 2600) Aggregation: Huawei B715 & Cybertech 17dBi MIMO

Question

Hello, what antenna will be the best for aggregation of LTE bands - 1800, 2100, 2600, the closest BTS is 1.7 KM from me. The router is: Huawei B715.

"Antenna Dual LTE-A / 4G 17dBi MIMO 1800-2600MHz" from Cybertech will be a good choice, will I find something better?
From what I read, this antenna has a bit mixed opinions, but most are positive.

If without the 800 band, the antenna is fine. As one of the few, it has almost full technical data, and more importantly - its parameters match. And that speaks well for her and the producer. In principle, there are no perfect antennas, each of them has some minor or major disabilities, contrary to what is listed in the technical data. So that in each case each antenna will behave differently, although this one should behave as it should practically always. As for opinions, however, each is subjective. However, not everyone knows how to use an antenna, not everyone can choose an antenna, not all conditions are optimal for a given antenna, etc. - and here there are negative opinions, usually unfortunately not having much to do with reality. On the other hand, there are hurray-optimism like because it worked for me! - sometimes against all logic or need, which again does not give much to the seeker ... Antenna like an antenna, but if you plan on a longer cable, more than a few meters, then antenna cables begin to be used, especially when receiving weak signals.

Standard, attenuation on high LTE 1800-2600MHz bands about 5-6dB / m. 5m of cable is a loss of about 3-4dBi of signal from the 17dBi gain of the antenna, purely it will be about 12dBi on LTE2600 and less on LTE2100, LTE1800. the antenna has an optimal gain at 2600MHz. in Play LTE2600 works at 20MHz width, so it is by definition the fastest, usually the least loaded and contributes the most to 3 CC CA B7 + B1 + B3. LTE1800 is 15MHz and LTE2100 is 10MHz wide.

Let's say it's the decency minimum at 2600.

Typical attenuation for 5 meters of cables at 2600MHz:

H1000___ 1.3dB

LMR-240_ 2.2dB

H155____ 2.7dB

Symbolic differences (except H1000), although if someone is fighting for every dBi of gain from the antenna, there is something to fight for.

I would use LMR anyway

The signal parameters on LTE2100 are the best and the bandwidth is therefore basic in 3 CC CA B1 + B3 + B7 (often has priority on BTS Play), worse on LTE1800 and poorly on LTE2600, but it's normal since the router is inside. Connection with BTS Polna because that's probably how the sectors are set on these 2 BTSs. Cybertech's antenna has a horizontal beam angle of 30 degrees, so you can check both BTSs by setting it one by one on them. LTE2600 should also work as a baseband, it is important because it is the widest band and the least loaded, UL on it is by definition 2x higher than on LTE2100, it is often useful, an antenna from Cybertech with a standard h155 cable or with another one and N connectors on the housing?

The antenna works fine, your signal parameters are perfect. Check how it works on AUTO.

Which operator which BTS? As the signal parameters on each of these LTE bands on the B715 look like, show the screenshots from HManager, LTEwatchH, the same with the B715 outside the window. What DL / UL on these bands

Hevce · Answer

Play network, the nearest BTS - 1.7 KM from me: and 2.4 KM from me another BTS: Tomorrow I will throw screens because only tomorrow I will have the router at home.

I need 5 meters of cable, Cybertech adds H155 as standard, I don't know if it's a good cable. They still offer an RF240 cable, maybe this one will be better?

Hevce · Answer

Is it better to take H155 or this RF240? The price difference is PLN 7 over 5 meters.

matek451 · Answer

Diversification about the selection of the cable without knowing the signal parameters outside on individual LTE bands is pointless, there is also no specific location, so it is not known in what directions BTS Play. In the case of purchasing an antenna from Cybertech at 1800-2600MHz and selecting a cable with lower attenuation, the version with 2 N) connectors is purchased z) led to the antenna housing and 5M cables with N (m) -SMA (m) connectors are purchased.

Hevce · Answer

Today I will throw screenshots as soon as I get the router. As for the location, it looks like this: This is the closest BTS.

Anonymous · Answer

Sorry, I automatically entered the name of a different cable, but of the same class as the RF240. And I will not agree here. The antenna cable is an independent part of the antenna installation and should generally always be of the best possible parameters, especially shielding. The higher the bandwidth, the longer the length, the more the attenuation becomes important. The transfer speed, apart from the BTS limitations, is directly determined by the quality of the received signal. This in turn, depending on the circumstances, depends on the signal level and the compactness of all disturbances in the signal. It must be remembered that the home is also a place where we have (or may have) a high level of interference. And a weak cable with low shielding is very susceptible to all kinds of debris from the air that can have a negative impact on the quality of the signal reaching the router's ports. In TV technology, with a weak antenna cable, good TV reception can be canceled using a poor HDMI cable, which may be hard to believe, but it happens ... Sure, the choice of the cable used will usually have a negligible impact on the transfer rates, because these depend mainly on other elements of the installation, but if the installation is well suited to the received bands and consists of good elements, then the chances of a long-term, stable transfer. And that is a completely different question, here we are talking about technical possibilities that can influence the choice.

Home router - no external antenna - 3 band aggregation:

HManager - aggregation of 3 bands:

LTEWatch - 3 band aggregation:

1800MHz:

2100Mhz:

2600MHz:

I don't know why, but it draws everything from this further BTS which is 2.4 KM from me. Why not pull the one closer - 1.7 KM?
Today the antenna will come, maybe it will jump to the closer BTS with the antenna.

Hevce · Answer

I ordered an antenna from Cybertech: Dual antenna LTE-A / 4G 17dBi MIMO 1800-2600MHz, in options I chose: 5 meters of cable - H155 and connector: SMA (m) - directly on the cable. There were no more options on the Cybertech website. Somewhere in 2 hours, the courier will bring the antenna and see what it will look like with the antenna. Added after 7 [hours] 26 [minutes]: This is what it looks like with the antenna: 1800MHz: 2100MHz: 2600MHz: 1800MHz + 2100MHz + 2600MHz: Is it okay or something wrong? Today I have a problem with this BTS on aggregation: Yesterday without an antenna on aggregation it was like this:

Hevce · Answer

Similarly to AUTO. So it turns out that 2 BTSs are clogged?

Well, it's not exactly that perfect - the situation, apart from the 1800 and 2100 levels, does not look good. The programs report RSRQ / SINR respectively:

1800 :: -13.5 / -4 (!) And -13 / -6 (!)

2100 :: -11.7 / -1.3 (!) And -12 / -5 (!)

2600 :: -7 / 10 and -4 / 19 - here it is OK

A :: -7 / 14 and -7 / 12 - here it is also quite OK

Aside from the fact that the SINR indications can be differently displayed by the equipment and do not have to be very reliable (the negative indication shows more noise and interference than the useful signal, i.e. de facto no possibility to establish transmission), RSRQ also clearly shows some problems. It looks to me as if the antenna is catching extraneous emissions at 1800 and 2100.

Hevce · Answer

There may be a problem with the antenna, cable or router? Or maybe BTS? SINR and RSRQ are average for me. Somewhere I read that SINR can be weak due to a clogged BTS, but I don't know if it's true.

Comparing these results to singles and router aggregation without an external antenna - post # 13:

A :: -6 / 12 and -6 / 13

from the reception point of view, apparently little has changed in aggregation - probably, looking at the singles results, aggregation without antennas was dominated by the 2100 band, and with the antenna - 2600. But, it seems that earlier there was much less interference than the aliens 1800 - 2100.

Hevce · Answer

But in my case, SINR and RSRQ jump every 1-2 seconds, it will show SINR 10 once, and in a moment it shows 0, -5 etc. RSRQ from -7 to -14 and so it jumps. RSRP and RSSI are stable.

Anonymous · Answer

Because BTSs do not have continuous emission, but in fact 'shoot' consecutive packages. Hence, depending on the moment of measurement, there may be more or less interference from extraneous emissions. I don't insist that you do, but it seems so to me.

It may be that without an antenna you had little signal and that could be causing problems. But the foreign emissions were so small that they did not interfere with the reception, 'hiding' in the generally perceived noise. With the addition of the antenna, both the usable and the noise levels increased ("getting out" above the general noise), and then you got a problem - you improved the 2600 band significantly and made trouble on the 1800 and 2100 bands.

Summing up - it all looks like an antenna with too much gain at 1800 and 2100.

And to verify this - question - do you have some 'foreign' BTS +/- in the front hemisphere in the direction of the antenna?

Hevce · Answer

Can a high gain antenna be a disadvantage? I always thought that the more profit the better. Alien in the sense of a different operator? Because there is no Play network.

Anonymous · Answer

As you can see, the high gain in pick-up (single km) can be a disadvantage.

"Alien" in any sense different from that with which you are connected.

I have already found - you are within the range of BTS from ul. Królewiecka 1 and probably the one from Polna 2A.

Try to use the good directional characteristics of this antenna to 'lose' this annoying company - you would have to turn it to the right (westwards) until the RSRQ and SINR readings improved. In this case, don't worry too much about the level, because you have a spare. You can look there - a similar situation -> Link

The X polarization antenna is hung as shown in the picture. It doesn't matter which cable to which connector.

Hello. I would like to ask for help in choosing the lte antenna.

Location: Tenczynek 32-067 ul. On the rocks (at the end of the road)
Router: Tp-Link mr6400
Operator: Play

The connection is very unstable and weak, although the tests give results around 6 mega, sometimes it is difficult to open the page, in the evening this net does not work at all.

matek451 · Answer

This router is practically not suitable for Play from BTS at Trzebińska 15, it is worth little, so buying an antenna for it is pointless. Without the antenna, it probably logs into the clogged, long-range LTE800, if you can give it back.

Qleslaw · Answer

I can give it back. So what set to buy?

matek451 · Answer

The minimum is B535 with aggregation of 2 LTE bands to use 2 CC CA LTE2100 + 1800 from this BTS, on it you will do outdoor tests and choose the antenna, but rather Dual LTE1800-2100MHz.

I understand well that you mean Huawei 535-232 such as below? I am a layman in these matters and I prefer to clarify
