This is a source run for an inverted L antenna for 80m that is 43 feet

What would be the simplest matching network to use to produce a flat match.
My primary use would be 80m low angle work at 3.7 and 3.5 Mhz, but also want
to be able to use it (with a tuner, of course) for a local net at 3.97 megs.

First of all, changing the match doesn't make the antenna change from
a "low angle" radiator to a radiator for local work.


While a 1.7:1 vswr at resonance is usable, I would like to get my starting
point as low as possible to maintain some sort of reasonable vswr at the
band edges, for those times when I need to check into the net.

By simple I mean no caps...they are not all that easy to find (in a hurry)
any longer. I need power handling of 500w. My two thoughts are some sort of
1/4 wave transformer (although that's a lot of coax), or a simple toroidal
transformer.

You can use a 1/4 transformer of two parallel RG-59 to get a nearly
perfect match at 3.7 MHz. But, you must realize that by doing this
you actually *increase* the SWR at the band edges. Any reactive
solution will do the same.

If you have a tuner anyway, I fail to see why you want to do this.
