question about cb with weather channels
if i get a cb that can access NOAA weather channels, do i need a specific type of antenna? Radio Shack sells a cb/wx (weather band ) antenna but its a magnet mount.
i'm assuming i do since the weather band works on a higher frequency but wasnt sure. thanks!

NOAA weather channels are in the 162.XXX Mhz range. They are always in a very high location and often push in excess of 300 watts ERP out of the antenna. You could drag a piece of aliuminum foil behind the truck and recieve NOAA weather radio. In other words, the CB antenna will work fine to receive it.

you fold little pieces of it until the SWR reads 1,203:1.
You calibrate the meter. You tune the antenna. You don't calibrate SWR. Put the meter on Calibrate or FWS and hold transmit. Turn the calibration **** until the needle is on the calibration mark. Then put it back to SWR or whatever the other setting is labeled. Key the transmitter. The needle reads what the current SWR is. You then have to tune the antenna to improve the SWR. Tuning the antenna involves lengthening or shortening the antenna.
Turning the calibration **** while it is in SWR mode to make the needle move is NOT changing your SWR, it is just changing the calibration of the meter and making read incorrectly.

Yeah its better to tune if you know how, or have someone do it, but I just bought a pretuned fiberglass one from Radioshack(yes i know its not tuned the best). It works though on my midland.
I also learned that having the weather channels is only useful if you live in or drive around large cities that broadcast- I opted to get one without.
Also a question to add. I have the pretuned fiberglass antenna hooked up now on the roof. If I buy another of the same and put them on oposite sides of the truck, would it increase incomming signal, or cancel each other out?
