LoRa antenna kit
Can I use another antenna than the 900 Mhz LoRa antenna kit and which you advise me?
In that antenna style I've had acceptable results with the ProAnt PRO-IS-212 https://www.digikey.co.uk/products/en?keywords= 1532-1023-ND
Could you please recommend any other alternative to Taoglas PC.81 worth trying?
The Molex is the worst antenna I've tested. Very poor performance.
What is your experience with Molex 105262? Is it comparable with Taoglas PC.81? It is much cheaper, however it seems to be unavailable in most of the e-shops right now.
Where did you see 8dBi? The LoPy kit antenna is FCC listed as 2.2dBi
In this topic I always had the doubt of the maximum gain of the antenna for the gateway, in Multitech support say to me maximum 3dbi, but I see that you use of 8dbi, what is the criterion?
Some may have a different connector, the LoPy has what's called an u.FL so you might need an adapter cable. From the listed the Laird and sticker type already have it, while you would need an N-Male to u.FL adapter (TaoGlas) or N-Female to u.FL (Sunhans)
Hi @jmarcelino thanks for your response,
I can use them on the lopy ?
Yes and there are thousands of suitable antennas, very much depends on what you wish to do it - do you want an external type antenna (big and robust), higher gain (more focused beam), small size (even like a sticker) ...
For example my deployments include the 1.5 meter TaoGlas Barracuda http://www.taoglas.com/product/barracuda-omb-868-08f21-868mhz-8dbi-omni-directional-outdoor-antenna/
The "Sunnhans" antenna: https://www.aliexpress.com/item/806-2700MHz-Omnidirectional-Fiberglass-Antenna-for-GSM-CDMA-PCS-3G-WLAN-system-SMA-male/32674489646.html?spm=2114.10010108.1000013.1.n9mcsi&scm=1007.13339.33317.0&pvid=2e27570c-cd4d-43ad-ab1e-0628d982816d&tpp=1
The traditional 1/2 Wave antenna (for example from Laird)
The tiny and cheap board mounted ProAnt http://www.proant.se/en/catalogue/embedded-antennas/--onboard-smd-antenna/onboard-smd-868915-antenna-pid55.htm
To an antenna which is just a sticker
You need to understand your criteria and go from there.
