the ground or roof surface??

Hi Myles,

Both. For purposes of feeding it, the proximity of other conductors
and sources of loss, the antenna is as close as that 20' you offer.
On the other hand, for purposes of propagation, your antenna will act
like it is elevated 175'.

Your experience, compared to others, will fall somewhere in between.
Personally, I would think you have a very nice situation. If you seek
to improve it, it would only be in shades of a degree, not in leaps
nor bounds.
