[Xastir] Portable Digipeater Antenna?

[Richard Polivka, N6NKO]

I agree about the windup j-pole. My complaint is that 300 ohm twinlead 
is not stable in construction or materials. I have had the geometries of 
a J change when rolled up, messing up the tunings. You also have to use 
a coax balun or beads on a J since it is a balanced antenna being fed 
from an unbalanced coax.

Just personal preference. Coax is more easily had than twinlead in an 
emergency....
