[Antennas] Question reg. multiband dipole - balun

[Joe Falcone]

This exchange about window/ladder line is helpful.  My present situation was meant to be temporary at the new house until I got my tower and quad up.  The tower is 
now up, but the quad is lying on the ground, waiting for spring and repair of some of the elements.  

Anyway, this is what I did:  I have a flagpole in the back yard.  About a year ago, I put up a dipole, about 130 feet or so long. One leg of the dipole goes straight north, 
the other goes due south then makes a 90 degree turn due east.   I ran a random lenght of window line out the metal framed window to the dipole, and closed the 
window on the line.  I then terminated the window line to a 4:1 MFJ balun.  I then ran coax from the balun to the tuner on the FT-1000D. 

I hit the tuner button and the automatic tuner brings the swr down to 1:1 on all bands at 200 watts. Everything seems to work fine, as I can work the dxpeditions fine 
with the 200 watts and QRP with 5 watts. I don't think I would ever want to run 1500 watts with this set up so I did not hook up the amps.  

Needless to say, I understand that running the balanced line outside by closing the metal window on it isn't the right way of doing things, and I will be drilling holes in the 
house this spring to run coax as well an appropriate method to get ladder line out, but, my question is:

What do you think is happening to the signal, if anything?  Is the antenna tuner simply taking care of it?  Or am I radiating a lot from the line instead of the antenna?  Am 
I likely losing signal to the window?  Is the window radiating?  How can you tell if the ladder line is radiating?  The antenna does seem to receive quite well and seems to 
get out every bit as well based on the fact that if someone 7 or 8 thousand miles away hears me in a pileup, something must be working OK.   I have my computer 
monitor sitting on top of my radio and if I broadcast without hitting the tuner, there is RF interference, (the screen goes weird), but as soon as the tuner kicks in, there is 
no RF interference. If the line is radiating, I don't know if that is a bad thing anyway.  My line does sort of travels horizontially to the antenna anyway, as my house is at a 
higher elevation than the flagpole. 

Well, I just thought I'd tell you guys about what happens when you sort of don't follow the rules.  Joe N8TI
