Finally made some progress on my APRS Buoy project.
This model only needs to float a few weeks for tracking ocean
currents and then be recovered. SO it only needs two lantern
batteries, a MicroTrak8000 FA tracker and Byonics GPS.
Today we finished the Antenna, and I must say, it is the first
coaxial whip dipole in a pipe that I have gotten the SWR down to
a perfect 1.0!

Hope to launch it in a week or so...
