The ground plane is a good choice. I built mine with an SO-239 and AWG #12 solid copper wire.
I used needle-nose pliers to put a small loop at the top of the vertical radiator so that I can run a non-conductive support line through the loop and hang the antenna from a nail or a limb or whatever.
These antennas work well.
Very slick idea ! Never even thought of the loop at the top concept. That would be a 'simple' way to get the HB GP way up high, via some rope, etc, over a tree branch.
I use three methods to get wire over a branch. For up to 25’ I drilled a hole in a baseball, and ran a loop of a zip tie. I tie some paracord to that and do an underhand swing in a loop and then let it fly. Takes a bit of practice.
To go 30-40 feet I have a kids bow from Walmart. Set a fishing pole up to the side open the nail and line tied to end (nock) end of arrow.
For 60-90 foot trees - yes I have some - I use my compound bow and it soars over them. But my home is fairly rural so now safety issues with neighbors.
After the fishing line is over I tie to pull paracord thru
I’ve raised jpoles made with 450 ohm window line and even my large comet gp-6 into trees. They both work great.
