022 2022.10.04 | (maintenance) install directional LTE antenna
|
|
|
|
|
--------------------------------------------------------------
|
|
|
|
|
|
|
|
|
|
The `gigacube-2001` sits inside one of the orga containers aka inside a big enclosed metal box.
|
|
|
|
|
To combat possible issues regarding the LTE connection I've installed a directional LTE antenna ontop of the container on an already existing mounting pole.
|
|
|
|
|
|
|
|
|
|
**antenna details**:
|
|
|
|
|
- `800/900/1800/2100/2600 MHz`
|
|
|
|
|
- one vertical and one horizontal array
|
|
|
|
|
- inside single enclosure
|
|
|
|
|
- `type-N` connectors
|
|
|
|
|
|
|
|
|
|
**antenna connection**: `antenna (type-N female) <-> (type-N male) 10m Coaxial Cable (SMA male) <-> (SMA female) Adapter (TS-9 male) <-> (TS-9 female) Gigacube` for both arrays
|
|
|
|
|
|
|
|
|
|
**antenna orientation**:
|
|
|
|
|
* loosly towards top of city block on `Philipp-Rosenthal-Straße 66, 04103 Leipzig` (nearest Vodafone `eNodeB`)
|
|
|
|
|
* "fine" tuned through moving antenna vertically and horizontally while monitoring signal strength
|
|
|
|
|
|
|
|
|
|
**gain**:
|
|
|
|
|
* increased `rsrp` from `-90 dBm` to `-74 dBm`
|
|
|
|
|
* current `rssi` is `51`

|
**important**:
|
|
|
|
|
from now on please be careful when moving things around near the gigacube.
|
|
|
|
|
The `SMA to TS-9` adapters are too long for the jacks on the gigacube and therefore the antenna cables have a very unsatisfying fit.
|
|
|
|
|
They could either damage the gigacube, be yanked out or both.
