So I am in the process of prepping my rv6 for a repaint. It is set up for basic ifr but I am not ifr rated yet. I am planning an avionics upgrade soon as well. It has two comm antennas on bell along with transponder, adsb, marker beacon, and vor antenna. It has an sl30 for nav. Should i keep the marker beacon antenna and nav antenna or should i get rid of both and just put a garmin 175 in? Now is the time to get rid of them since i am painting.
