Hi Ed and all,
I have had two Mitsubishi split systems installed for the past 6 years. No
noticeable RFI from them on HF or 50 mhz. The tower and antennas are located
approximately 50-60 feet from both the outside units and the inside units. The
model numbers are as follows: System 1 - indoor unit , MSZ-FE18NA-8; outdoor
unit MUZ-FE18NA and System 2 - indoor unit MSZ-FE12NA-8, outdoor unit
MUZ-FE12NA-1. Hope this helps to build your list of “RF quiet” systems.
73,
