Paul,
As mentioned, you can use a commercial diplexer, or split it by making yourself a lpf for 2m
and a hpf for 70cm,easy and cheap.

I'm looking for a filter suggestion to reduce the third harmonic (435
MHz) of my 145MHz 100W signal. How much attenuation would I get from
a simple 435MHz quarter wave stub?
Thanks
