Measured with a RigExpert AA-1200 antenna analyzer, the SWR using this coax is higher than expected. With the FlightAware 1090 MHz 24" antenna it's over 1.7:1., With the DPD Productions antenna it's 2.1:1. I have a feeling that a 50' run of this type of coax is just too long to get good SWR. I suspect that most people don't have an antenna analyzer capable of going to 1.09 GHz so most people don't know the difference. I was expecting less than 1.5:1 on both of my antennas especially since the antenna is mounted in the clean on 23' mast.
