I recently bought the kit with 3 * Xbee Pro S3Bs ( 00mhz). This kit also included the 2.1db antennaes.
Intially I had then set up using only the presoldered wires and got a 100 or so meters in LOS.
Subsequently I have solderded on some RPSMA connecters and attached the antennaes but the range has gone down instead or up.
I have verified the soldering and everything is clean with good joints..
I have no background in antennaes and must admit that my knowledge is quite basic, I have read many of the beginners articles in the web but nothing seems to be pointing me in the right direction as to why my range has gone down instead of up.
I have my XBees in API mode, they can connet without any problem, I can send and recieve data but just can't increase the range.
The 1st Xbee is placed at my garage door, and the others are connected to a portable PC.. ( All are connected to Arduinos, either Nano's or Megas.. ( no problem with the arduinos or the code). The antennaes are connected directly to the Xbees.
All are set to HighPower (4) and have the usual networking params.
Where and how should I begin looking, debugging in order to determine why the antennaes are not producing better range...
Thanks in advance for any advice that you can offer..
