[FieldDay] Mast inside a section of tower

[Mike Wells]

Ron,

We have a 30 tower for FD and to rotate the 3 ele tri-bander we run the mast
all the way to the bottom. We use vise grips to rotate and secure the mast
so that the antenna doesn't free wheel. We found this is much less
cumbersome than ropes hanging all over the antenna. My two bits.

Mike

   It is not a field day question, it is a tower question.
   You start with a 40 foot mast ...
A rotor with 50' of cable is better, or put up a Moxon.
