If you want to add VHF capability to the DB4e, you can add a separate VHF high antenna - it does not have to be the VHF retrofit from Antennas Direct. The Antennacraft Y5713 is only $30

I am currently using a setup like this with a Y10713 above a DB8e on the same 10' pole, and an Antennacraft 10G221 preamp

As ADTech mentioned, you could also go with a large combo antenna, like the Antennacraft HBU type
http://www.antennacraft.net/Antennas/AntennasHBU.html - here "large" means "long" ... the Y10713 has a 10' beam and the HBU55 has a 12' beam.
