Hi,
I have a number of products with nRF905 successfully deployed. Now, I am in a little struggle with a new one. The problem is the signal strength. The other products have a proper antenna connected through SMA connector. Due to real estate limitation I had to change that to a solder in wire. I used a single core copper wire of length ~173mm. Unfortunately the signal from it is a lot weaker.
Would you have any recommendation? Are there any procedures for changing the antenna matching components to better match the antenna I used? I used the recommended components for 433MHz range.
Thanks Witek
