I just purchased a mobileone COL6MSK D-4098 fiberglass rod 6db uhf cb antenna from DickSmith in Adelaide. After unpacking it at home, I noticed that something within the fiberglass rod is rattling when shaking it gently. This is pretty much from the middle upwards. Is that normal? I just want to double check that this is the way it is supposed to be before I mount the thing onto my bull bar.

Thank you very much in advance for your help.

Surely not normal............

Go back and see if another one rattles.

CH,
Lot of that type seem to rattle, but don't know if it does any harm. Probably a bit of wear in very corugated conditions. Have heard of blokes putting silastic inside, but then some another bloke said it might throw out the tuning???

Have bought some from Access Electronics in Rocky that are filled with some goo and don't rattle. And work well.

Mobile One gear should be good, they've been going forever. Make a top AM/FM radio aerial, better than any of those chrome things.

Hooroo...

Seen it all, Done it all.
Can't remember most of it.

Well, it is a brand new rod, so I don't expect it to rattle straight out of the box. Dick Smith did have another one, so I might go and talk to them about the problem.

thanks, cruiserhead.

Gidday,This is quiet normal.The outside is only a cover for the radiating element which is connected at the top and is quiet loose.

She be normal, it's got a dipole inside, I had a 4.5db Aliminium Mobile 1 Dipole that rattled from new had it mounted on the bullbar for years, it's now mounted 15m up in the air at work on a mast and still works fine.

Here is the official reply from Mobile One. Good service, quick reply to my question. With 5 years warranty, I might just keep this one and see what happens over the next few years of usage... Thanks everyone for your replies. CruiserHead

The D4098 is DC Grounded so it will read a dead short at the base also the antenna may rattle , this is not too common
but it is of no concern , if the Antenna rattles to the point that it annoys you we are happy to replace it

the antenna is very solid internally and will last for many years with the worst sort of rattle
we do everything we can to make the antennas so they dont rattle , i am sorry you have one that does

But I can assure you that it can rattle 10 times worst than it does and it will not affect the performance or the life of the antenna
