[ANT] Can I use a PCB antenna on 169 MHz? You can, but it would require a very large PCB. Normally we se a helical wire antenna being a better solution.

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] I would like to ask you if you have some reference design for usage of chip antenna with 868 MHz RC1181-TM.
