Paralleled Zipcord could give a good match. However, an antenna 
tuner/transmatch (e.g: 
http://www.zgitaly.it/italiano/area.asp?sez=5&id=32) doesn't compensate 
for loss in the feed line.

Loss in the feedline can also reduce SWR due to mismatch _*at the 
load*_.  100 feet of RG58 *[at 146 MHz]* has an SWR no worse than 1.7:1 
no matter WHAT it is connected to, shorted or open; half the power is 
lost traveling outward, and half the  reflected power is lost coming 
back. http://www.hamradio.me/antennas/swr-vs-return-loss.html

We now return you to your scheduled topics.
