[BC] Part 15 radio station

If the tower is grounded at its base, then the tower _is_ the ground 
lead/wire.  If it isn't, the tower still is one arm of a dipole.  Either 
way the tower itself will radiate, unless the Pt 15 tx is insulated from 
the tower.  Even then, the program and power wires leading away from the tx 
will radiate unless they are decoupled for r-f.

The elevation pattern of a vertical monopole of more than 5/8 wavelength 
wouldn't be optimum for producing groundwaves.
