[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 1713 Antenna Q&A Related Knowledge Base Posts -[ANT] Can I use a chip antenna on 169 MHz?[ANT] “We will perform a radiaton pattern measurement in a lab (no certification, only performance measurement). For that we need unmodulated Tx on lowest and highest channel. – For the non-HP I guess we can use the: RC24xx_2405_TX_UNMOD_0xF5.hex RC24xx_2480_TX_UNMOD_0xF5.hex – Can we use this for HP as well, is the PA and LNA controlled with this FW so we get the full power? “[ANT]”Is a flexible antenna (a wire) simply soldered close to the RF-Plane sufficient aa antenna – or a perpendicular soldered stiff wire with quarter wavelength over a ground plane leads to the best result?
