[ANT] I have an existing 2.4GHz design. Now I want to change to an 868 MHz solution. Can I reuse the antenna? No, the antenna made for 2.4 GHz will perform very bad at 868 MHz Last Update: August 8, 2017 January 11, 2017 2598 Antenna Q&A Related Knowledge Base Posts -[ANT] “The problem is that that demo kit has a much longer range compared to the design. When we mount their homemade wire antenna onto the demo board the range is like 250 meter in-line with our needs. However on our own design it is only 50m range. Everything else work fine. Is this an issue on the PCB or an Antenna matching/design issue? “[ANT] Is it possible for modules to share the antenna?[ANT] I would like to ask you if you have some reference design for usage of chip antenna with 868 MHz RC1181-TM.
