How to make a CB radio 1\4 wave base antenna

The design of this antenna is derived from common antenna theory and is based on it's intended operating frequency and the appropriate formulas as known in antenna engineering.

instead i don't use colid core cable but tv cable is the same?

@nikos839 I'm not sure what kind of TV cable that would be.

I am wondering do you have to strip the coax for when you solder the female connector you were breif in the details about that so do you have to strip the coax and solder the braid to the ground tab that is on the female connector? Also what kind of coax did you use. I tried it with comcast coax and the braid is a type of aluminum or steel and will not solder to copper wire at all. I have tried flux also silver solder and rosin thick solder as well. Any recomendations will be thankful.

@anekon2 Hello, my apologies for my very late response. Yes, you strip the ground shield of the coax then solder it to the ground tab of the connector. Check for shorts in the connectors after finishing the soldering and assembly. Use RG-58 Coax, it is the cheapest and most fit for this project. Others for CB use inclde RG-8 and RG-213. Comcast coax will not work as it is 75 ohm impedence instead of 50 ohm as your CB station requires. This could result in damage to the transmitter.

about how much is the total cost?

[FelixTheHouseFreak]

@JohnBayn My apologies for my late response. The total cost for me was right around 5 dollars or so which is the ammount I paid for the PVC materials. The rest I was lucky enough to have lying around the house. I would estimate the total cost for those who don't have the materials lying around to be no more than 20 dollars.

@FelixTheHouseFreak ok thank's

that brush-on electric tape might work for you. its better than tape if you use a few coats

@Gatorbobpa Hello and sorry for my very late response. You are correct, one 102 inch length of copper wire as the main driven element, and four 104 lengths which will be your ground radials. The correct length of coax is whatever length you need to reach from your antenna to your radio.
