Dragino LPS8 Indoor LoRaWAN Gateway Antenna

Hi,

I assume the external antenna of an LPS8 is meant to be for LORA. But, I can’t find any confirming information. There is nothing in the manual and even google doesn’t have a picture of the gateways backside. Can anyone confirm, that there is an SMA connector for an external Lora antenna?

Thanks, Michael

There is no internal antenna. The sma antenna connector is for a 868/915MHz antenna for Lora.

It’s a standard sma connector so you can add extension cable and/or alternate antenna. One problem with supplied aerial is it is a 90deg fixed so could limit positioning/placement for some. Just be careful with choice of connector m/f, std vs rp etc.

thank you @kersing, @Jeff-UK. I thought so, but it also could have been the wifi antenna. you never know…

There is an internal antenna: the WIFI-antenna. The antenna for LoRaWan is connected by the SMA-connector. I measured the small white external antenna with a VNA: it seems to be usable between 860MHz and 920MHz.

Hi I am also considoring purchasing a LPS8. Would you recommend it?
And if so: is there an external antenna you would advise?

The one it ships with is fine as if you get a ‘better’ higher gain antenna you will need to dial back the tx PWR to stay within regs… unless by external you mean one to be placed outdoors in harsher environment on a feeder cable…then the higher gain of new ant can be used to offset the cable and connector losses? My test LPS8 has run fine for 5-6 months with only occasional outages triggered by changes to/loss of WiFi connection ( I moved from wired to wireless enet after few weeks at test site). I’m told latest firmware corrects for poor recovery after WiFi loss, though haven’t had chance to test myself yet as unit is remote and am in lockdown/site not yet accessible even though close by :frowning: My impression is good value for money with flexible connection options so go for it and let us all know how you get on/your experience…

Thanks Jeff, I just ordered one and will evaluate the indoor antenna performance before I try out an outdoor one (indeed my question referred to mounting one externally).
Good observation that the higher gain would well offset the cable losses.
Once I get everything up and running I will post a report.
