[TowerTalk] Schedule 40 pipe or HD aluminum mast?

[Louis Sica, Jr.]

To Steve and others who asked:

The current plan is a Tennadyne T8 on that mast (8 element 13-32 LPDA, 38
lbs, 8 sq ft wind load). Future plans are for the possibility of a V/UHF
antenna (maybe even the T31, 50-1300 LPDA, 17 lbs, 3 sq ft wind load)
