I am currently using a 150' randomwire for 80 & 40 meters. Its
connected to the "wire" terminal of an MFJ-949 tuner. Been happy so far
with the conntacts made.

I'm considering taking an turning it into an endfeed windom simply by
running 450 ohm ladder line from the MFJ-949 to the top of my 30' mast
which current supports the randomwire. I'll be cutting the randomwire
at the mast and soldering one side of the 450 line while letting the
otherside of the 450 line not attached to anything.

Is there any advantage of doing this? Basically I'm taking a 150'
randomwire and turning it into about a 120' endfeed windom, will it be
worth the effort?
