HI Tom,
If the mast is not metallic it probably doesn't matter.

That is correct, not a repeater set up, but, I like the idea of vertical
mounting. This makes things easier. But I still ask, how far from the mast, off
to the side, should the lower antenna be? I'm thinking some distance not being
an equal fraction or a multiple of the bands involved, that being the ham 2
meter and 70 cm bands.
Thanks again!

In general, where one is a receiving antenna for a repeater, it is
usually given the advantage of height, over the transmitting antenna,
which can compensate with greater output power.

We need to mount a vhf/uhf aluminum HAM band j-pole and a COMMERCIAL
vhf/uhf, (Comet GP->6NC), 153-157MHz, 460-470MHz, fiberglass vertical
antenna, (10ft tall, 3.5 lb weight), on a cross >boom.
He's not running a repeater setup. 2 x ants, one is a J pole and the
other is for commercial freqs.
