Also, don't rule out stubs as part of a solution. Carefully tuned stubs
built with beefy coax are typically good for 20-28 dB of attenuation,
depending on frequency. There's some good stuff about this on K1TTT's
website, and a lot more on my website.

Stubs are REAL easy on lines feeding monoband antennas, but switching
gets very tricky on multiband antennas because the switching network
becomes part of the stub.
