At least 70 watts has gone through mine, when a few of us at the AMSAT demo station at Dayton in 2019 hooked up an IC-910. Still works great!

I have used mine with 30 watts quite frequently over the past two years that I've had it and it still works fine.

I think the power rating assumes a more broadband application where a significant amount of RF is being attenuated. When you're using it to cut off the third harmonic from a transmitter, you're really only asking it to block and convert to heat a few milliwatts of RF at most, the rest is passing through.

Steve,

It's been extensively discussed on Twitter @AMSAT a while back and I can relate from using my FT-1634 setup using the BLP-200, it is a non-issue for SSB and FM at 5W

Dual HTs will be fine. Many rovers are currently using it with no issues with more than 5W power. Obviously not recommended for high power use!!!

Don,
I have considered the Minicircuit BLP-200 for use in my two radio set-up, but Minicircuits rates it for a maximum input power of 0.5 W. Do you transmit through it with a full 5 W or do you bypass it for transmitting or ???

I forgot to mention it in this post that you need to use a filter on a 2 radio setup to prevent desensitization.

Mini-circuits BLP-200 and MFJ-916B are 2 that I have used, and I know there are other options.
