So the instructions here are clear for installing external antennas in the Puli XE300
The holes in the side are a perfect size match for any SMA connector.
Now I don't know much about antennas, frequencies and so on. I got a similar antenna to these:
With these specs:
- Frequency (MHz): 698-960MHz & 1710-2690 MHz
- Gain: 2/5 dBi
- Connector:SMA- Male
- Impedance (Ω) :50
- VSWR: < 2.0
There's a cell tower on top of my apartment building, I can't say for sure I gained any speed even while on the same band, but the speeds and connection is more stable. I tried an stubby antenna I had (seen in the pics) but it only supports 900/1800 and it was mostly garbage speed wise.
I compared the connection status and this is the results.
| External | Internal | |
|---|---|---|
| Band | 40 | 40 |
| RSRP | -80 | -89 |
| RSSI | -48 | -56 |
| RSRQ | -9 | -13 |
| SINRl | 15 | 12 |
This was from the stubby antenna
| Stubby | Stubby |
|---|---|
| Band | 40 |
| RSRP | -79 |
| RSSI | -45 |
| RSRQ | -14 |
| SINRl | 12 |
Speeds
Internal 22Mbps/3Mbps
Large Antenna 25Mbps/4Mbps
Stubby Antenna (900/1800) 12Mbps/0.5Mbps
I will try to get a proper 4G antenna, these are all cheapo junk-market antennas that costed me 5USD for the large ones and 3USD for the stubby ones.
- Unplugged the red connectors
- Connected the IPEX1 to SMA Female cable and passed the SMA through the hole, then tightened it up with the included hex nut.
