Indeed, and I referenced that in my initial email,

So the plan then I guess would be two 10T for <30MHz and a "few" 2T for
50MHz. It's been said here that the inter-winding capacitance of the 10T
chokes lowers the isolation at 50MHz but does anyone know by *how* much?
Are the two HF chokes merely "useless" or are they actually "bad" at 6m,
such that maybe including a 6m antenna along with 10-20m is just a bad idea?
