Re: Radar ?
The most over-looked specification is the beam width; then combine that with transmit power. The "range" (i.e.16 mi, 24 mi, 36 mi) is misleading.
If two units have the same power, lets say 2 kW, but one has a 5 degree beam and the other has a 6 degree beam, the 5 deg. version will have (geometrically) better target resolution the farther out you look. It's all about power per unit area (watts / cm^2). With relatively low power units and wide beam angles, you will have a hard time seeing a small target at longer distances (5 to 20 miles).
If all you care about is being able to see targets within a half mile or mile, it is less of an issue. But don't be too surprised if you can barely see the shore 14 miles away with a low-end, 6 degree beam unit that says "16 mile range".
