Yes: Commercially would install many antennea specifically for receiving
specific bands, I.E. 2-6 Vhf, 7-13 Vhf, and/or Low range of UHF only.
We found mounting the actual heads at different altitudes with respect to
the ground had major effect on the db levels of the received signals.
After a period of time we actually created a rough graph using the
ac***ulated datum and used that information through out our service area
to
provide reliable reception to our customer base.

Deja-vue regarding TV reception via OTA. Cheers
