All of your stations are strong, there should be no need for any amplifiers as long as you properly select a mounting location and face the antenna the correct direction. You have signal margins in excess of 40 dB for most of your stations. You should be able to feed a two-way splitter and several hundred feet of coax without an amplifier.

The DB2e is the wrong antenna for San Francisco (unless you add a VHF dipole for ch 7-13, in which case it should be fine). It should do fine on all the UHF channels out of the box. If it didn't, there's something amiss somewhere that needs to be fixed.

Our normally recommended antennas is the ClearStream 2V mounted in a location so that it can "see" Mt Sutro.
