I did run a tvfool report before installation and thought since it is close enough (27 miles LOS) , the db4 might pick it up - - guess not.
the tvfool report is here:

also,
http://www.choisser.com/channels.html shows that KGO 7 is transmitting with the lowest power among all the Sutro tower broadcast tenants - and they have an application for a 2 kW station on monument peak under consideration so things may improve.
there doesnt seem to be another worthwhile VHF station in the area so i think i wont go with a special antenna for KGO / (ABC) for now --
