Dana, A couple of hundred watts would be enough...I have a Microwave Modules transverter, a brown-face Mirage 100-watt brick, and a pair of K2RIW-19 antennas, all obtained "on excellent terms." Kicking it old school. I'm not really thinking of upgrading beyond 100w any time soon... 73, --Ethan, K8GU.

Dana, Most common power dividers will handle 1KW at 432 and lower frequencies. The limitation is typically the input side N connector. A DIN connector could be used to insure 1.5+ kw on the input side, with N connectors for the 2 or 4-port ends.

I disagree on one point: Most common power dividers only handle up to a watt or so and are intended for small signal applications. These are widely available through Mini-Circuits and any number of other RF and microwave component suppliers, and in some frequency regimes can even be easily home built. Anything that can handle hundreds of watts qualifies as "high power", and is a whole other ball of wax. It would have been helpful if Ethan had mentioned the desired power handling capacity in his original enquiry, along with a rough number for the desired port-to-port isolation (which is yet another ball of wax since it depends on the transmitter's output impedance, rarely near 50 ohms or even known with any accuracy.). Cheers all, and I hope you have a good time at the picnic. I miss getting up north to visit now and then.

Kind apples and oranges. Commercial vs. amateur radio. Dana high power or uses of power dividers in ham radio mostly falls in the stacking of antennas or amplifier building which kind means needs to handle power as we hams like to transmit occasionally and HP on U & Vhf.

Randy, perhaps my judgement is colored by the fact that I've had zero interest in transmitting for a long time. My interests lie virtually-solely in reception of off-the-air signals and analysis of phase stability of any narrow-band components I can exploit. To each his own ...
