I constructed an extended double zepp for 10 meters out of #12 solid house wire . I didn't have any ladder line laying around so I decided to make my own but all I had was some #10 stranded wire. I made the spacers 1" apart and and put about one per foot and the total feedling is approximately 25 ft. and it's going through an MFJ 941E Versatuner . I can't get my SWR's below 2 . I'm sure there are a lot of varibles here but I was hoping someone could point me in the right direction.My first guess is that I should have used the #12 for the feedline and the #10 for the antenna . Thanks in advance , Will Seems kind of strange the tuner would not match it.. The spacing probably has more effect on the feedline Z than the wire diameter. Shouldn't really be that critical. The wider the spacing, the higher the Z.. I guess you could try a different length of line.. Or scrounge up some other ladder line, maybe with a different length. Even 300 TV line would be ok if it's not wet. Myself, I used to feed them with coax, and coax series transformers. I imagine you could also feed with coax and use twin matching coils at the feedpoint for both sides of the element. Same as matching a 5/8 GP, you are just doing the same with a complete antenna. I've never tried it, but it should work. MK |
