I am a new ham, passed my Technician and General. I would like say the words of wisdom, "I am in over my head" Before I got my license I purchased an antenna for shortwave listening. I have an 133' wire, 9:1 balun and coax into the house. The person I purchased it from said it should work on transmit when I get my license. I purchased a Yaesu FT-890AT yesterday and performed some tests. The internal antenna tuner seemed to work but I don't think I was transmitting with any usable power. Another run of the internal antenna tuner returned Hi-SWR, So I stopped there. My NanoVNA also shows effectively infinite SWR. (Tested on 80, 40, and 10 meters) So now the question: I have been reading about EFHW antennas, seems like I should get a 49:1 transformer to replace the 9:1 balun. Am I on the right track? Thanks for any advice.
