I am using two 443 MHz transceivers (FY-605 transceiver) with both having different antenna lengths. One antenna is around 12cm long and the other antenna is around 17cm long. Will this cause problems? And does it affect the range or doesn't it work at all? Also the ±12cm antenna is connected to the transceiver with a coax cable. As far as I know this doesn't cause harm. Can anyone confirm this for me?
