[Towertalk] Re: Any glaring discrepancies? -- Summary

[Jim White]

this bri gs up an interesting question....

how close to the top plate should one put the bottom antenna in a stack...

mechanically placing it as low as possible mean a smaller "moment" affecting
the mast...

I like having enough room for an automotive jack to raise the mast up by
pushing on the boom...this make a rotor swap out duck soup...

But there is the question of electrical interaction with the tower...which I
imagine is lower when the bottom antenna is higher...

Thoughts?
