Ant 8 now has it's dipole installed.
Could not find anything wrong with antenna 2.
Antenna 14 had a dipole rod snapped off; replaced it.
Antenna 17 had a loose connector at the balun, LCP side; fixed.
I keep forgetting that antenna 16 does not have a low band up-converter
and won't until it is upgraded.
