video we're going to take a quick look-see-loo at the mfj differential t-tuner this is a roller inductor tuner rated at 3 000 watts this is rated at 1 500 watts peak envelope power for single sideband so let's take that and um go at roughly i'm going to say four to 500 watts am or fm would be about a probably about a safe power rating for this and um rms wise and uh yeah it's kind of a neat unit actually i have really enjoyed this i bought this in late 2007. and i ran this quite a bit in my station i actually ran two um stations at my house in washington state and i had my little mfj 941d on my smaller station in my bedroom and then i ran this one in my larger station on my radio room and um really got a lot of use out of this thing so generally i don't like using an antenna tuner per se as far as tuning an antenna i like to get my antennas pretty close to resident frequency or whatever
