You might find a surplus commercial 160 MHz Low Pass Filter in the used market. That would work just fine for what you are looking for. I also like Mike's idea of using a duplexer like the Diamond MX-72H. The unused port will need to be terminated with a 50 ohm dummy load.

The first question I would ask is if 100w is really necessary. After that, you may want to look into using a diplexer as a low pass filter or find a dedicated 2m LPF.

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
