CB Radio Information and Installation

@Sandman614, thank you for your post on antenna mounting and tuning. Over the weekend I figured out my problem. The antenna I have just isn't compatible. I hooked up a friends antenna, and it brought my SWR readings down into range. I'm going to get a new antenna and check it again.

 

You cannot tap into military frequencies b/c we are on different waves than civilians. Plus we don't use CBs or HAM.

 

What length and type do you need? I have a 4' firefly firestik laying around now. I meant to order a 3', which is on the way now. So I have a 4' laying around. Brand new still in box.

 

Interesting. What antenna do you have and what antenna did does your friend have?

 

Mine is a kw4 firestik 4'. He has a tunable 5' firestik. I have to check my receipt but, I believe I can upgrade the one I have.

 

any threads you recommend for a car radio noob like me?
I want to join the air force eventually - hopefully I will learn more about communications.

 

Nae man I can't. I'm just getting into CBs myself. I just know a little about military radios and freqs to get me by and through shit.

 

Ok guys, I thought he had a tunable 5' firestik. well as it turns out its just a kw5 firestik (5'). So after doing some research my 4' antenna is 400watts and his 5' antenna is 500watts. I was wondering if I could just get a 4' tunable antenna which is 900watts? If someone can explan to me the differents between the different watts between the antennas, I think that would help me a lot in understanding how it all works.

BTW: my SWR readings are ch1- 2.8 and ch40- 3.5 with the 4'
ch1- 1.5 and ch40- 2,1 with the 5'

Thank you!

 

CB only 'legally' outputs 4watts, so the branding of 500watts/900watts is silly. If you really want to really look into something research 1/4wave, 5/8wave, etc. If the antenna is labelled for CB and fits your need of Ground Plane vs No Ground Plane(boat, RV, motorcycle, and other low ground plane installations), then it should be good. The length will help you transmit and receive performance, generally longer == better. You need to Tune your antenna. If it doesn't have a tuneable tip(screw) then you will need to cut it shorter, even if the readings say it's too short you can't add onto it. Too short is relative, antenna "lengths" and repeats themself, so once you take enough off it will be too long for the next "length".

Pics of where it's installed?

 

Car stereo or Ham/CB radios? if the latter, check here

So it sounds like I should go with the 5' tunable.

As for the mount; Its mounted on the right back corner by the tail light.(I know left side would be better but, its also my company truck. Left side would be in the way). I have it grounded to the frame. Checked it with my meter, hot is hot and ground is ground. Coax is ran behind the tail light, along the frame, into the cab from under the passanger seat to under the center cup holders. I'll post a picture tomorrow. One thing rhat I'm concerned about is my bed rack is also reading grounded to the truck and antenna ground.

 

Thank bro. Know any good shops in Phoenix?

 

nah

 

Picture of install:

 

Everything seems to check out. You just need to Tune your antenna, whatever length you prefer. It's also possible your 4' antenna is damaged.

 

What do you do to tune it? Both SWR readings are high. All I found was on if one or the other was high.

Thank you for all of your help!

 

Remove the spring and check again. It's likely the spring is a problem.

Read this too.

Thank you! You have given me some more homework for the weekend. I greatly appreciate all for your help.

 

This is another good read.

I'm getting a Galaxy DX-98VHP radio. Getting it tuned from bells cb in florida. With a Wilson 1000 magnatic roof mount. I have a 2017 TRD ORDC W/ premium and technology package. Can I mount the antenna close to the shark find on top of the truck? Or does there need to be some separation?
