CB Antenna help 04 Disco

I am a new member to EE and was wondering if anyone could help me out on what kind of CB Antenna I should get and where I should mount it. I have seen pictures on the site of mouting them on the spare tire mount? Is this the best place?

Thanks

It depends what you want out of your radio.

If you consult with the EE fashion police (and who doesn't) they will tell you that the only place for a CB antenna is on the spare tire carrier. However, for the best range out of your CB radio, the antenna should be mounted in the center of the roof. Where you choose to mount the antenna will effect which antenna your should choose.

For roof mounting, I like the Wilson 5000.

What ever your decide... make sure you tune the antenna with the radio before you use it.

While you might get the best use out of it on the roof i believe the spare tire mount makes the best sense.

First - It does look better. You can't see the mounting or the wiring, and i'm sure the range isnot greatly reduced. If you're useing it while off roading chances are you only need it for short range anyway.

Second - I live in the North East US and lower a vehicle is the better. Up here we have trees and they can hang low... CB antenas mounted on the roof just catch limbs and can stress the antena and bracket. Even mounted so it extends rearwards can be a problem when catching limbs in reverse.

Go spare tire mount!

The whole issue is about priorities. If all you are doing is talking between trucks at a couple hundred feet, a 2' antenna on the spare tire carrier that stays below the roofline will be adequate. But to believe that the range will not be greatly reduced is foolish. Have you ever measured the SWR on a 2' antenna on the spare tire carrier? You would be lucky to get less than 2.5., which is not a good thing.

If you have a roof rack, a short antenna on a spring mount would solve the problem of banging around tree branches.

What I don't like about the spare tire carrier mount option is that when I mount a 4' antenna to get some range, it moves all over the place and bangs into the top of the door when driving.

What Mike said hits the nail on the head.

Truck to truck at fairly close range... go for looks, to hell with range.

If you want range though... you've gotta go with the roof mount.

The problem I have with my roof rack mounted Wilson 5000 (with the 100w booster ) is that my range is so much greater than anyone elses. Other people hear me but I can't hear them.

The VHF is next...

Why not just go straight to HF?

Imagine how nice one of those massive motorized HF antennas would look on a SD rack.

Yeah baby!!!!

I could have... CB antenna, 2 cell antennas (phone & modem), VHF antenna, HF antenna, GPS antenna, FRS antenna... did I miss anything?? So do I mount them all on the roof rack or on the spare tire carrier???

So if having too many lights is to be spidered out, what is having too many antennas? Porcupined out?

Mike,

Try putting a tennis ball on the antenna. Just punch a hole in two sides and slide onto the whip where it keeps hitting the roofline.

It looks weird, but after I did this I never had a problem again. I'm sure all that banging didn't do any good for the match of the antenna either.

Tennis ball? Ewwwwww!

That's definitely an offense the fashion police would frown upon.

Another example of function over fashion

When it comes to CB, making an argument for any kind of function is worthless.

mike, i've used a 3 footer K40 fiberglass whip. real thin. no base spring. just a quick disconnect. it never hit the body of the disco XD.

i've observed that the stiffer firestick on a spring base hits the body of the disco very often.

Tether the antenna to the spare tire so that when the antenna wags toward the vehicle the tether draws tight before the antenna hits.

Leave the tennis balls to the Retrievers.
