Thanks Roy,

I should have mentioned the trees are in position for a broadside array to
fire in the (two) directions I need.

I would use the trees that currently support the 30m half square firing
NE/SW.

The problem you'll run smack into with any fixed antenna is that to get
gain in one direction you've got to take away gain in others. So the first
thing you have to decide is which directions do you want to improve your
signal in, and which are you willing to sacrifice. Then consider where
your trees are. Only then can you begin to consider what kind of antenna
might deliver what you want.

I have some space and some high trees. I already use a 400ft doublet with
atu for several bands and a 30m half square and get good results. I want
to improve my performance on 17m. I am now thinking about a wire
antenna with reasonable performance for 17m only. I have thought about a
full wave loop, even a bobtail. A broadside array would be great but I
am not keen on antennas with reflectors or directors because of the
complexity of support ropes. So, really some kind of antenna supported by
ropes from two trees would be ideal. Any ideas please?

A horizontal 66 ft. dipole fed with ladder-line would
work for 40m-10m and give you some gain over a 1/2WL
dipole on 17m where it would be an Extended Double
Zepp. EZNEC says feeding it with 9 feet of 450 ohm
ladder-line and then coax the rest of the way gives
a pretty good single-band match on 17m.
