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

1 Mar 2016


      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,
