Does a CB radio with WX need a special antenna?

I wouldn't think so, an antenna will have to be resonant in the CB range, for transmitting, it doesn't have to be resonant in the range where you're getting the Weather from.

For the middle of the CB frequencies, a quarter wavelength would be electrically 8.6 feet.

For the NWS weather bulletins, they broadcast between 162.4 and 162.5 MHz, for which a quarter wavelength would be around 1.44 feet. This means that a quarter wavelength at 27.185 MHz, the center of the CB band in the US, would be just about a wavelength and a half at 162.4 MHz, the bottom of the weather band.

For a receiving antenna, that should be fine.

For receiving antennas, close counts, adding one more to the list of horseshoes and hand grenades.

No..If you have a decent CB antenna, you will hear the weather channels fine. Even though they are located in the 162 Mhz. range. They have several frequencies, and your radio should hear the closest one.. If there is a seperate antenna connection for the WX channels, a small 2 meter antenna with a mag mount or a 20 inch piece of wire should work fine..

Although you will get the best results buying an actual CB antenna, I have picked up the local weather stations using standard speaker wiring. But it will be better to buy an actual antenna:

There are better ones available. Now I have heard that calibrating the antenna will get you even better results but I don't have experience with that. I bet another user could help with calibration. Good Luck!

you cant use the police antennas on cb radios/the police use fm together as the cb is am/flow to radio shack and notice in the event that they are able to extra wholesome you up/want an swr meter to make confident the antenna and radio tournament up/those products should be finished on internet site/no longer many adult adult males around with that information anymore/the handheld radios have knocked plenty out of the corporation
