I'll be moving my rig to a second floor OP here soon, I've always been
at/below ground level with a short run to a ground rod. I'm only
running a trap dipole nowdays and I don't want to get into the mess of
a counterpoise. Can I/will I get an acceptable ground by running a
ground strap to a ground rod? I imagine that a lot of folks are doing
this - is there any advice regarding getting it grounded from this
height?

tnx - Mark/n0lf

Mark,
Sounds like a 'balanced' antenna to me, why a
ground other than for electrical purposes (not RF)?

I needed to hear it from somebody else, that's all.

I'm not quite balanced in the feed, as I'm using coax out to the
dipole feedpoint, but probably close enough.

tnx - Mark

A W2DU choke would probably eliminate the need for
an RF ground and also be good engineering practice.

I have a 2nd floor shack too, and the antenna is a ground mounted vertical
(Butternut HF6V). I use a W2DU choke to connect my coax feedline to the
vertical and a 2nd W2DU choke between my Orion and Drake L-4B. Finally, I
found that the only way to prevent feedback on SSB was to NOT connect my
system to the #8 ground wire that runs out the window sill and down to a
ground rod.

Yep, everyone should realize that a ground wire is N*1/4 wavelength
at certain frequencies, and at those frequencies, is an RF transformer
that locates the standing-wave voltage maximum points at the transmitter. (ouch!)
That's what artificial grounds do - change that *electrical* length
to N*1/2 wavelength. For anyone insisting on an RF ground for an upper
floor, an artificial ground is probably the way to go. I, myself, prefer
balanced antennas and feedlines.
