I am buying a new vehicle and I have a minor issue. The roof mounted whip aerial is too long and when I go in and out of our garage it will strike the garage door(tilt door).

 

Is it possible to cut these shorter without loss of reception?

 

alternatively, is there somewhere in Wellington anyone can suggest I could go to find a replacement shorter aerial. I would like to be able to just unscrew the current from its base and

 

screw in a new aerial.

 

I have included a representative aerial similar to the one on the vehicle I am buying.

The length is a deliberate part of the antenna design, if you alter it in any way you will most definitely alter the reception characteristics (for the worse).  I'd suggest a different antenna or mounting point instead.

Can you not fold it down flatter?

Does that mean one cannot screw another shorter aerial into the mount? or are they matched to the vehicles radio?

If it does unscrew, then just take it off alltogether and see how you go.

Why not change the whole aerial for one of those euro design ones that look like a shark fin.  Get it color coded to the car for a extra flash look...

 

I am sure you local radio installer could advise something appropriate, may even be able to test a couple of options.

Some car aerials have more than one function, some do GPS, some do cellular phones and some do satellite radio ( not an issue in  NZ ).

 

You might be able to buy a stubby aerial off trade me ( cheaper off ebay ) and see how you go.

 

Most just unscrew

 

DO NOT cut the antenna that you have.

 

While it is that  length for a reason it is not so much of an issue for receiving hence the stubby aerial.

The whip aerial on my last car unscrewed so you might be lucky. I don't know if it's still a thing but they used to do "coil loaded" aerials that had a spring section in the middle, or towards the bottom - something like that might give you some flexibility for a lower garage door.

I tried a "stub" aerial for my car but reception was terrible. In the end I just pulled the rubber end cap off, cut in half, spray painted and replaced rubber end cap. Reception is okay (I don't listen to radio much) but I agree with the above and look for a proper replacement.

 

PS My aerial appeared to be made of fibreglass or something, I had a few splinters in my fingers afterwards so be careful.

i thought that newer cars had the antenna in the windscreen and any car that had one of them just above the back window there was a good chance it was a undercover police car  especially if it was a ford or holden. Guess i was wrong.





Common sense is not as common as you think.

Usually you will find a plastic one with a wire inside or a wire wrapped around a fibreglass rod and heat shrunk.

 

I have not heard of bad experiences using a VW stubby one.

 

Wouldn't surprise me if someone bought a stubby aerial that was just a hold plug with a plastic spike.

When I take delivery of the vehicle, hopefully tomorrow, I will have a look at it. Anyone able to recommend a good installer in Wellington? There was one in Railway Ave but they seem to have gone.

Exactly. Mine was off Ebay, so there's your answer.

Maybe I should pinch the one off my wifes' Skoda while she is away :P

OK, I know about wavelengths and I know how aerials work. If this one is only for reception, does it really make such a huge difference if it is a little shorter? Reception will be a little weaker on AM, but I doubt if it would be very noticeable. The question is what this would do to FM. The answer I see all around me is those portable FM radios with antennas telescoped in and out at arbitrary lengths. It might make a difference for difficult out of town reception, but is it really going to matter in the city? I have had plenty of radios with makeshift wire antennas and they all had at least some reception. I have even had a car radio with no antenna connected at all, and that had some reception. If there is a coil inside the antenna to make a tuned circuit for FM reception, I can see how cutting the aerial might destroy that. Otherwise I don't know why it would make a huge difference.
