I can't speak for your specific situation, but here is how I handled
the similar situation.

I used either a multi-band-parallel dipole (sometimes referred to as a
fan dipole) or a 135 foot dipole fed with 300 ohm twin-lead. These
antennas were raised about 100 feet or so into trees by mason's line
which can be purchased at Walmart or most hardware or building supply
stores.

. . .

While I still use it today, I don't recommend it for anyone wanting to
put up a permanent antenna and just leave it alone for more than a
year.

I don't think it works equally well for all kinds of trees. For many
years I've used nylon twine or mason's line for raising Field Day
antennas. The trees here in the Pacific Northwest are of course mostly
evergreens which have a lot of pitchy sap and in many varieties, fairly
soft wood. An antenna with a fair amount of tension causes the line to
dig into the wood in a very short period of time. And even after two
days, the line can sometimes be hard to get down because of being seized
in the pitchy slot it cuts in the wood. So while it's fine for a very
short time temporary setup, I don't consider it viable for longer term
installation in the kinds of trees we have here.
