WB4AIO offers some excellent information and I would like to add the
following:

Generally speaking, (Note I stated GENERALLY SPEAKING here) end fed antennas
tend to be most directional in line with their longitudinal axis. In other
words, an inverted-L, end fed, would pick up the greatest
capture in the direction that it is "pointing."

Center fed antennas GENERALLY tend to be most directional perpendicular to
their
longitudinal axis.

Again, I stress these are VERY BROAD and GENERAL rules of thumb. Of course
there
are always exceptions such as the center fed Zepp which tends to be most
directive off its
ends. As one respondent stated...experiment. There is a reason they call
technical suppositions "theories."
It is because they are just that, theories only. Real world performance is
whatever you get and can be
morphed by ground conductivity, nearby structures, interactions and terrain
as well as theories that are conventional but one day will be refuted.

Thanks, Clive - my room to experiment is extremely limited, but I will
do what I can.

I like that last sentence and believe it.

...and I'm gonna use existing trees to put it up about 30 feet above

higher voltage, but not real high-tension wires.

All other things being equal, am I better off:

- 1 - Putting this thing up parallel to,
- or more perpendicular to, the powerlines?

Most of the time perpendicular.
Also keep both ends of the Antenna wire
as far away from the Power Lines as possible.

- 2 - Having the coax meet the wire at the base
- of the tree and grounding it there,

IMHO this represents the better 'safety' Ground
and the Inverted "L" Antenna is the better Omni-
Directional and All-Band SWL Antenna.

Plus running {burying} the Coax Cable under-the-ground
even if it is only 4"~6" is better than on-the-ground
{tripping} and up-in-the-air {noise}.

- or running the coax up the tree and then depending
- on the outer braid on the coax for ground purposes? *

IF you have to run the Coax Cable from the Roof
to the Tree in-the-air then this works.
* but use a Ground Rod at the base of the Tree
and a Heavy Ground Wire up the Tree to the
Matching Transformer, Coax Cable and Antenna
Wire 'connection'.

- The coax is grounded at the first termination point at
- my MFJ antenna phasing unit using a short, heavy
- copper wire to a ground rod.

Short and Heavy Ground Wires are always preferred.
