I've just got a 97 GTi with o.e. beesting aerial and the m.w. reception on the stereo is very very poor, however, the f.m. is perfect. Does anyone elses have this problem, or have any ideas of how to cure it.
-
My Audi had that problem (same aerial).......couldn't get MW at all. The amplifier (thats in the base of the aerial) was knackered. Got a replacement aerial from GSF......very cheap.
Another thought, you have got the remote out from your head unit connected to your aerial haven't you?
-
I think it's all connected up, sounds like its the amp problem.
If I got an new aerial is it easy to fit? Would I have to remove the head liner etc and fix a new lead?
-
With my Audi, I was able to get at it by removing the rear ceiling light and a trim panel so it was quite easy and it was a straight swap. Not sure that you'll be so lucky, got a feeling you do have to remove the headliner.

The areial does not make any difference, it is only a piece of metal, if anything it could be the amp at the bottom of the areial if you have one, or its you stereo or you reception.

I think you'll find - that the Bee sting aerial is for FM only.
The head unit will have a ferrite bar inside for AM frequencies.
Maybe you have a gash receiver? :-\

I think that used to be the case but not so now.......certainly with my Audi which uses the same part number aerial as the Golf. Have a read of this:-
'If you have problems with radio reception don't be quick to blame the head unit; the problem my lie with the radio antenna. The OEM factory antenna employs separate amplifier circuits for the AM and FM bands. These circuits are designed to boost the most radio signals possible while filtering out unwanted stations and noise. These microelectronic circuits are housed in the antenna's base while the receiving element consists of a spring loaded, wire-wound, fiberglass mast designed to withstand most automatic carwash machinery.
Symptoms of problems with radio reception include poor FM reception (only strong stations tune in), and virtually no AM reception. Other indications of faulty antenna operation include audible "pops" heard on the AM band originating from turn signal or windshield wiper relays. The culprit to these problems may be that the antenna is not getting 12 volt power, the antenna is poorly grounded, or the antenna amplifier may be bad. The worst case scenario is that none of these problems is the cause and the radio itself is bad. If you have an aftermarket radio, the antenna may not be receiving power or you may have an ill-fitting antenna RF cable adaptor. Regardless, to troubleshoot for the source of the cause will require gaining access to the antenna and power connections at the back of the head unit and at the base of the antenna.'

Shurley it's dependent on the receiver - rather than the capabilty of the antenna. I agree the 'beesting' can receive both AM +FM - but what is the spec of the head unit?
I ain't saying you're wrong and I'm right - but I think there are variables in this equation. :P
If he has an older type unit - maybe, perhaps>??????? ???
I dunno - but you learn summat everyday don'tcha?

I have to disagree and say the quality of an aerial is vastly underated, you need to have a good reception point for the amplifier in the receiver unit is only going to amplify noise. Try plugging an old aerial into the head unit and see if you get a difference.I speak as a qualified communications engineer, so hopefully I may be of some assistance - and stop calling me Shirley ;)

You misunderstand
- i'm referring to head units having built in MW antennas - and wether the capabilties of a bee sting aerial would impeed the quality of MW recetion.
NOT the pros and conms of gash/quality aerials - a good aerial is always better than coat hanger obviously. ::)
-
I don't doubt that there is always the possibility that there could be a problem with the head unit and you're right, depending on the type of head unit, it may only use its own internal aerial as opposed to the bee sting for MW.
I didn't realise that head units were still manufactured that only used their own internal aerial for MW. :-\
-
I am the opposite - I didn't realise MW utilised the FM antenna.
But what the hey.
I'm just saying it depends on the head unit.
-
The bee sting aerial has 2 amplifiers in the base, one for MW and one for FM. My Audi MW amplifier had failed hence I couldn't pick up MW at all. It now works a treat without any interference so I guess my head unit uses the bee sting aerial and its amplifiers. Best ?10 I ever spent, I can listen to all my sport now. ;D
-
SORTED!

Sounds like I've started a pretty lively debate!!!
The head unit i'm using is a Sony XR 4440 that I run my cd changer from, but when I got the car I used my panasonic single cd unit for a while and the MW reception didn't work then either.
The power to the aerial interests me. How does that work?. Would that only affect the MW reception?
Any help would be much appreciated as I don't really want to remove the headlining to fit a new aerial.
-
You use the 'remote amp' wire from your stereo so that when you switch the stereo on, power is then supplied to your aerial.
My FM worked and I had no MW prior to replacing the aerial assembly. On replacing it, My MW worked and my FM improved.
Mine is a Sony head unit too, although probably a much older model.
-
You have to replace the central component for it to work right.

Changing the aerial on a mk3 isn't too difficult, ive recently swapped my old beesting for a Blaupunkt amplified DAB unit. Running new leads wasn't as easy...
