Genericly speaking, the should be longer than the duplexer that would be required for a ham split, because the wavelength is longer at 410MHz. Even if they aren't tunable, it's possible to cut off the bottom, remove some amount of metal, and weld them back together. -- Kris Kirby, KE4AHR Disinformation Analyst
