[TowerTalk] DB224 and polyphaser(s)

[chas]

We are installing a DB224 for 2m operation on the doghouse on a 12 story
building.
what sort of polyphaser(s) are we going to need for the coax going thru the
bulkhead to the 50W repeater, etc?
we have one that looks like a dbl female, barrel connector with a ground wire
attached to  it.  is that sufficient?

iow, I THINK that this grounds the braid... again, is that sufficient?
