The last couple of flights have been in light rain and solid IMC and I have very poor reception with lots of noise.  Basically the brand new IFD 440 sounded like crap with lots of static even when we did get reception. Today we had to push the volume button and listen to a lot of noise just so we could hear center so we didn't miss a call. Anyway,  I have two of the 7 antennas on top of the cabin and the rear one looks like it is brand new. The front one has taken a lot of abuse over the years w
