If you have the time to work with surface mount parts, Marki Microwave sells some SMT bias Tee's for around $50. I didn't see a spec for max RF level on their web site but it might be worth looking into. I bought a few of them one time to protect the ports of my VNA by grounding the DC input terminal. They've worked very well.

I'm purchased 2m and 432 preamps for my satellite antenna system and both will require external bias-tees for power. Looking around on both US and UK/EU websites I've found bias-tees that cost almost as much or more than the preamps did. The inexpensive devices I've found are receive-only and meant for SRD users.
Does anyone know of a source of bias-tees that cost less than $100.00 each, have decent specs on 2m and 432 and can withstand a transmit power of 50 or 100 watts. (Yes, I know I don't need to run 50 or 100 watts for satellite work but I don't want devices that will fail the first time I accidentally transmit "QRO".
Thanks
