Outer Limits 4x4 Board

Found this aerial in my truck after I bought it. No idea what it's for. Any ideas? I can't see anything written on it apart from RFI.

uhf

Could even be for an old school mobile hands free kit. Have you traced back the lead it was attached to? May give you some more clues. One of the radio enthusiasts would probably know what its for and whether its worth keeping.

wasn't attached to anything. Was sitting in the little ledge that runs around the inside of my car where the roof attatches. My guess would be old school hands free thing but no signs of where one was mounted in the cab (this doesn't rule it out though)

looks like a VHF aerial to me as UHF aerials have there spring up higher towards the center

definately a UHF one.. i have heaps of them.

spring is in the same spot mine is. i still vote uhf

Yes, it's UHF, and it's even for the UHF CB band.

It might be the top half of a CD94, or it could be a Phasemaster CSW whip - either way the blue tag would indicate it's for 470-490MHz (so UHF CB).
I think the whip on a CD94 is a CSW anyway, so regardless it's a 4.5dB(i) antenna.

Looks like a UHF to me. 1/4 wavelength at the bottom, coil, then 1/2 wavelength on top.

Well there you go. I thought the coil was just so it didn't snap when I drive into stuff

it does help with that too
but if you use it with an elevated feed then id recommend using a spring base also..
i found out the hard way on a tight track one night

If there's a second grub screw at 90 degrees to the one you can see its the same as a UHF antenna I had
