Hi Doug
Ignore those splitting hairs. :)
Yes, and inverted L will represent a load that should work for your radio
without any additional tuners (should).
I run an inverted L right up the side of an 80 ft pine tree and then I have
4 elevated radials. 2 of those radials parallel a fence that surrounds a
Tennis court. Not much I can do about it. The horizontal part goes over
to another tree. Many say the fence will detune the antenna, but I don't
see it and it closely resembles the numbers when I plugged them into AO
(Antenna Optimizer).
To prevent the winds from tearing it apart, I have about 30ft of UV protect
shock cord on the rest of the horizontal part before the line heads down
the other support tree. Since I added the 1/4" shock cord, I have not had
a fracture in the antenna. In the past, when it did fracture, I had to
take the Quad Copter out and re-drop a new line. :)
My antenna is NOT SWR flat across the entire band, which is good. The
flatter the SWR you have the more ground losses and less radiated signal.
I forgot what my 2:1 SWR bandwidth is, but it is about 1800khz to 1905 or
so. It depends if the ground is frozen or not.
I've worked the world on this antenna. Short story, I highly recommend you
build it and try it. If it works, awesome. If it doesn't try something
else. It is just wire and you can re-use it. If you get this shortly
after I right this, you can look at my PSK Report Link for FT8 and see what
parts of the world I was heard in tonight even with the solar storm.

I hope that helps, Mike va3mw
