Dan,

I would invest in one of the popular antenna analyzers and check the
antennas for the resonant frequencies of the bands you operate.  I live in
the country and have adequate space for single band antennas for the bands
that I operate.  Remember that the multiband verticals or beams are
compromise antennas.  You sacrifice bandwidth due the traps for using a
single radiator (antenna).  When I build and erect an antenna, I use an
antenna analyzer for the fine tuning.  When I have the antenna fine tuned to
my desired operating frequency, I develop a VSWR, impedance and operating
frequency chart.  I date the chart and place the chart in my radio room.  If
possible, I do not use an external or a built into the transceiver antenna
tuner.  The tuners absorb RF power and I want the maximum transfer of RF
power to the antenna.

Also remember, most transceivers if they see a high VSWR (>2:1) will reduce
the RF power from the PA transistors.  That is called a protection circuit
which is part of the transceiver RF section.  My Yaesu transceivers have the
protection circuit.

Good luck with your project.

Best 73,
