Bought a cobra model 29, hoping to install it in my truck. Ive seen antennas but, need some opinions on what all I need to buy to have this cb installed and working in my truck.

Much obliged.

That will do antenna wise. As far as the tuner if you don't know what you're doing the best thing would be to take it to a pro. If you do know what you're doing, have fun.

need a base, antenna, coax cable, and a good source of power AND ground....


then take it to a cb shop and have it peak and tuned, or peak tuned...

they hook up a meter and adjust the swr's close to about a 1.5 reading on the meter as they can, and send you on their way


unless you run a linear amp, the (all) cb's transmit and receive at 4 watts.... on an untuned setup that is about 1-2 miles... on a good tuned setup you can see up to 15-20 miles, and with a linear amp you can see forever, as the truckers say.

the 29 is a good radio, i have a little micro uniden 510pro xl, and am looking for something different.
Peaked and tuned on the radio is different than tuning the antenna system to the vehicle. The SWR meter is temporarily installed inline between the radio and the antenna, then the antenna length is physically adjusted to closely match the electrical length of the RF signal being transmitted. I prefer the antenna style that has a brass screw at the end of the antenna, that way I can fine tune the physical length without cutting any wire that can't be put back.

CB radios also transmit and receive using AM signals. Factory radios transmit using a low wattage signal, then 'swing' up to but not exceeding 4 watts -- the max allowed by FCC rules for unlicensed radio operators. A peaked radio will have the ability to deadkey 4 watts, then 'swing' more than 4 watts, which is what gives the radio the ability to talk out the 15-20 miles. Tuning the antenna will increase the ability of the radio to transmit that signal, as well as the ability of the antenna system to effectively transmit that RF signal to the receiver inside the CB radio.

The different channels on a CB radio correspond to different frequencies in the RF spectrum. An SWR meter will generally be used to tune the antenna system on channel 19 to an SWR as low as 1.2, which will keep the SWR on chanel 1 and 40 to around 1.7, and the channels between somewhere inbetween. Keeping the SWR below 2 will keep your transmitter happy, and increase your reception range, keeping your operator happy.

If you have the room, I'd highly suggest a co-phase setup -- two separate antennas using a Y-cable off the back of the radio. It will also add to your transmission and reception range, being that CBs are held to small power transmission every little bit helps.

cophase is cool, if you have a semi truck, otherwise you will just look like someone that doesnt know what youre doing. whatever antenna you get, make sure its atleast 3/4 of it is above the cab. if not, you will enjoy talking to either yourself a lot, or those behind you. i swing about 350w max.
