While grounding the mast may not do as much for the noise as you would
wish, it will make the antenna perform more like the specs say it
should.
This is because it depends on the grounded mast to partially replace
radials.
I know it's a half wave antenna, but without a ground, you are losing
a lot of rf back down the coax.

As I would have suspected, the imax is a great transmitting antenna.
Receive is not as good. True, if I can hear it I can work it, but the
noise
floor is higher. I am wondering if I ground this mast to an earth
ground,
if that will help. The noise is a constant s8 on fifteen meters. The
vertical doesn't get out well on 20, but is s units better than the
zepp on
17 and up. I have never used a vertical before.
