Re: Mode S test

Just as a satisfied user I can confirm having had a Sandpiper 23cms helix up
on the chimney stack for the past 12 years looking at one of our ATV
repeaters and it is still working fine.

I can not comment on the "real" gain but it feels nicely directive and the
SWR is still good. It has also survived numerous assaults by birds.

I also have a spare one ready to use for P3D.
