They should be individually tuned to the same frequency,
then adjusted the same amount to trim them, and since they
are now a dipole, would be best fed with 72-75 Ohm line.
They can be mounted on anything, I have a 15 meter unit
at the top of a 10 foot piece of 1/2 inch (trade size)
EMT. (interior electrical conduit with a cap on top,
hose banded to a sewer vent pipe on the roof of my house)
