Hello George,

On my first reading, I imagined that you were considering
replacing the 30-foot, single-wire, vertical wire running
from your tuner to a 120-foot horizontal wire with a 30-foot
length of ladder line. Based on the responses so far, I
wonder if I correctly understood the question.

If my understanding of your question is correct, you now
have something like an inverted-L, with potentially
significant radiation from the vertical portion.

Changing the single wire to ladder line would probably
cancel most or all of the vertically polarized radiation and
would probably do little to improve the radiation from the
horizontal wire. You won't get much low-angle radiation from
a horizontal antenna at 30 feet, no matter how you feed it.

It is difficult to say whether you would notice an
improvement with your contemplated change. I'm inclined to
think not. A better move might be to consider putting down
some radials. What frequencies are involved here?

Also, as some of the responses suggest, there are divergent
views on the end-fed Zepp.

Be interested to hear how others see this.

Good luck.

Chuck

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?
