And around 50 watts. You don't need any more power than that, it is just wasted.
At VHF/UHF frequencies the signals are line of sight. They will go slightly past the horizon, but even doubling, tripling, or quadrupling your power will not give a meaningful increase in range. For example, two radios I like, Yaesu FT-1900R at 55 watts, and FT-2900R, at 75 watts. These radios operate identically, same buttons, same menus. But for the power, there is no difference. And the extra 20 watts of the 2900 will give you no more range. At best, that is a half a S-unit signal increase. The higher power unit is70% larger by volume, or turning it around, the smaller unit is only 60% of the size of the larger one by volume. The 1900 is smaller, lighter, easier to mount, and just as effective. Pick your radio by features other than a few watts of power. |

This is true unless you have alot of background noise caused by some sort of interference, then the extra wattage helps get you through the static. My inlaw's have a transformer on their power pole that plays havoc with my radio whenever I'm at their house, but if I use the amp (160 watts, 2 meters) it really helps to break through the static to talk simplex. |
