This is 10m RF getting into your 15m yagi. A filter on the 10m amp will
achieve nothing.

You need a coaxial stub on the amplifier end of the feeder to your 15m

RG213 or similar with VF 0.66 will require a 23ft shorted stub.  This will
null both 20 & 10m RF.

A lot less expensive than an high power BPF.
