Few if any uhf radios go all the way to the 50 watt level. That's fine though, as there is no discernible difference between 40 watts and 50 watts.
I strongly recommend that you avoid those Midland radios. They are nothing but rebranded Chinese radios with a hugely inflated price tag, and their performance is subpar. A real commercial radio in the standard 25 watt power level will outperform it, and the commercial radios are also available in a 40 or 45 watt version. Best of all, you can buy two or three good condition commercial radios plus programming cable and software for the price of one Midland MXT400.
Or, skip the programming and buy your commercial radios from a seller who will program them with the frequencies you need.
