Do megahertz or watts measure the range of CB radios?

Answer 1

-- Megahertz . . .

That's the unit of the number that describes the frequencies of the CB channels.

All of the CB channels perform pretty much the same, and you don't have control

over the frequencies anyway, except to pick your channel.

-- Watts . . .

That's the unit of the number that describes the power that comes out of your

antenna (whip) when you transmit (talk). If nothing else changes, you can

figure that 4-times the power gives you double the range, 25-times the power

gives you 5-times the range, and 100-times the power gives you 10-times the

range. But don't get carried away. The power of your transmitter is limited by

federal law, sticking an external 'linear' onto your CB radio is illegal, and the

only thing that's limiting your range right now is not the power coming out of

your radio when you talk, it's the 3-ring-circus of interference that you hear on

CB right now, caused by all the other people who are running illegal linears.
