[amsat-bb] I wonder if this commercial quadrifilar helicoidal antenna any good?

[Alan]

Drew,

I have the 2 m version, which is usable, at best,  for satellite reception.  It has been repurposed to
a portable APRS digi where it is doing a good job, though certainly not a cost effective one.

73s,

Alan
