Paralleled Zipcord could give a good match. However, an antenna
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
We now return you to your scheduled topics.
