Hmmm... MFJ doesn't shed much light on what is in the "matching section". Hopefully, it's not a 50 ohm resistor! Maybe it is a 9:1 balun and this is like an end-fed wire. But then there is this from the manual "Raise the antenna and mast assembly up and mount in the final position. For best operation it is recommended that the antenna be put up about 35 feet in the air although reasonable results are obtained with a lower height". So they are hoping to use the mast as part of the radiator...The other problem is that you would like to operate on 80 meters and only have 28 feet of antenna. So, I'm not sure where I'm going here with your problem. Maybe something in breaking down and arcing in that "matching section". If it's a 9:1 balun...that might be why it's only rated at 150 Watts CW?

Rf in the shack? Trouble shooting ideas?
