I'm looking to buy a new antenna to go with my Cobra 25 LTD. I have heard a lot about the Wilson 1000 and the K40. Just curious which would be better? |

Thanks Bruce,
Would you know anything about elimateing static noise on the CB while the engine is running. I going to hook the CB straight to the battery to see if that helps. Let me know if I'm the right track. |

Thanks Bruce.
I'm just looking to improve a little on transmit and recieve without getting the 102",
Thanks again |

There has been BOOKS wrote on redusing engin noise i find directly to the battery helps and placing the antenna away from the motor does too at CB i would think unless your spark wires are not resistive the problem should be small check with the company that made your car sometimes they have service releases on how to cure this get a ferete bead from radio shack and put it in your DC wires just before they go through the fire wall to choke off anything comming that way to be honest i dont have that problem only other thing is MAKE SURE YOUR ANTENNA HAS A GOOD GROUND! I seen bad grounds mess uo things good!

Hey Bruce, I was just wandering how I could make sure I have a good ground on my antenna if it is magnetic base that I have atop my 4wheeler. Would the paint cause a problem? Or with the magnetic base that gives me a good enough ground.
Thanks for your help. And Also, I was wandering about you email.wa4gch. Is that Ham? and if so where back East are you from?
My Dad is wa4dsd on Ham...

Hi All,
I was looking at the Wilson antennas and I have a ? I was thinkin about the wilson 1000, but then i started looking at the W 5000. Just was wandering which one yall would run. Again I have a Cobra 25 LTD Classic. Would I notice a difference between the W 1000 and The W 5000?
Thanks for your input.

Chris magnetic antennas are at best Ifeee on CB how ever both the wilson ( i dont remember the model but it looked just like the k40 )and k40 i had were mag mounts and did fairly well. I dont realy know if you could see a change between the 1000 and 5000 i always say if they are about the same lenght they will work about the same. Now nothing beats a good ground for cutting down on car noise and mag mounts will dig up your paint although i used clear rap under the antenna with good results. if you can look into a good trunk lip mount if you have a trunk thats what i use on 10 and 6 meters and never had a problem with them. Now if your stuck with a mag mount and your a bit of a machinist get a ground at the base of the antenna and run it to a car ground |

Bruce,
Thanks again. I didn't know about putting something under the mount. But I'll do that now. and with the ground wire, thats a good idea. One of the locals here was telling me about that just today. and between the W1000 & 5000 there is only 1" difference & only $10 more. I just thought for $10 more why not..
I'll let you know what I choice and how the locals like it....

Chris,
either of those choices will work fine. One good thing about either K40's or Wilson magnet mounts, usually your SWR's are low and without worry, and they talk just fine. Especially if you are looking for something easy that will work, you have been led in the right direction. All are good so enjoy the CB'ing.

Bruce is right about the coils on the K40's...they have a tendancy to crack with time...now the Wilson's will last forever! I went through several coils on the K-40 before I finally bought the Wilson 1000. I have had the mag mount and the trunk mount Wilson 1000. They both performed well for me.
And Bruce, you're thinking of the 'Lil Wil' that looks like the K-40. I think it's the Wilson 500? I could be wrong.....

I know mounting an antenna through the body of your vehicle gives a better electrical ground. However, I have used mag mount antennas for cb as well as 10 meters and I can tell you they will work. You do have to spend time tuning them. My 10 meter whip is a Radio Shack cb antenna cut down to 10 meter band. It is below 1.3:1 from 28.100 to 28.600 with a flat swr at 28.400 or so. My cb antenna is also a Radio Shack mag mount($29.00 or so??). It is about 1.2:1 over all 40 channels[1.1:1 on 20] Getting these type of matches took a long time and some tedious cutting/adjusting. On a car, the roof is the best spot for any antenna be it cb or amateur. I know lots of folks say Radio Shack stuff is junk, but with the right effort you can get good results with their antennas.Model 21.972 is the closest current antenna to ones I have, which are both over 12 years old.(I clean and check them at least twice a year)
Good luck with your selection.

kb5lpa,
Thanks for the info. I just went to radio shack and got a 102" whip. i mounted it on the bed rail behind the cab.. My Swr's are 1.2 to 1 across all 40 channels.... i have gotten a lot of info on here. i'm glad i found it..
I have also heard that mounting a 102" whip on the rear bumper of a vehicle would work better too...
Tahnks for you advice..

Chris,
Keep that thing as close to the center of the mobile as possible with a good SWR. That way you won't necessarily have to turn the truck around when you talk to someone. If the antenna is on the rear of the vehicle, you will talk more toward the front. If you have a small vehicle, you will talk a LITTLE more front and back than from the sides. No, it's not like a beam if you mount the antenna on the rear of the vehicle. You just won't hear as much behind you.

Dx431,
No worries, but i would still like to see your set up.. Like i said i just got a 102" whip and mounted it behind the cab on the bed rail in the center.. My SWR's are good. Im reading 1.2:1 across all 40 channels.... still want to redo my mount... I would like to fold the antenna down when not in use...
My email is 4ofusinaz@msn.com look forward to seeing your pics... Thanks... |

I have a 102" whip on my truck that dosent work to well. I have it on a custom mount that I made for a ball mount. It is mounted right behind the cab on the driver side. It worked awsome on my old truck but not very well now....I might try running a ground to the frame and see if that helps or not..I would also be interested in seeing some pictures of both of your setups to give me some ideas..
Thank you

Buck,
Im in the process of putting my 102 on a ball mount which is on a custom bracket.. Right now i have the whip in the center of the bed rail.. I drilled a hole to mount the bracket to that way i would get a good ground.. Once i get the ball mount mounted and i get some pics Ill share with you and Dx431

Grounding the mount to the chassis does make a difference. Also check that coax. |

Tech671,
Im getting ready to mount my new custom mount to the bed rail using bolts to secure it. Is that a good enough ground? or do you still recommened running a groung wire from the mount and connecting it on the chassis somewhere....
Would the rubber bushings on the bed mounts be causing a improper ground??

Chris,
By all mean's go ahead and run a ground wire from the Mount to the Frame. That way you will never have to worry about weather it is a good ground.
With the Spacer's/Groument's/Bolt's the factory uses on mounting a lot of the bed's you can never really be sure that the bed is really grounded good. By going directly to the Frame you will Eliminate any problems.
And as 671 stated CHECK THAT COAX!

Your bed is of course grounded or your lights wouldn't work. It is NOT grounded to the point of creating a "ground plane" or RF ground. I'd recommend a large (4ga) fine stranded ground from the mounting bracket to the frame.
Whatever antena you use, if it has a coil you want the coil above the cab roof line. |

Chris Hooking up directly to your battery might help, or hurt. If your Ign. wires are old and are breaking down your power wires could act as an ant. and pick up a buzz.
Back in the old days of generators and filters we used coax as a power cable. The rigs drew a lot of power "Tubes" so we ran RG-8 using the "center conductor for Pos" and Shield as Gnd. It helped a little on some rigs.
Add an extra ground to your radio it cant hurt with all the plastic in theses vehicles. |

Chris I forgot to add. You may be able to use RG-58 since the new radios draw less current. And fuse it at the Battery.
A 1961 VW goes up quick when the coax shorts with no fuse on it. My CB pal did save his 108" whip and ball mount. |

Galaxy .... you got that right ! Do you know what you call anyone who dosnt fuse at the battery ??
A FOOL ! Back in the 70's i had a fellow ham who had a VW and the battery was under the back seat well he did want to lose the .2 volts across the fuse After it shorted he didn't have to worry.

Bruce: That's dumb for shure My buddy didn't fuse it because the Heathkit had a built in fuse in the radio thats dummer. It shorted under the drivers seat
Did he do the all out noise reducing my buddy did? Ign. noise was so bad he had braided shield on all his plug wires to ground trying to get rid of it. His 108" was on his front bumper on a 3 ft' pipe. We kidded him to put to up another one so he could claim it as real bug with two antennas. |
