Need a new Ariel for my 90 so as I can have a decent radio.

Got a cassete player with LW and MW at the moment:eek:

Got a roof rack so where's the best place to put it and what type (cheap)

Are those military whips with the big base any good for me wireless:)

Them military ones are for UHF & VHF radio. they will probably work but it's a bit of overkill I have a short rubber aerial mounted to the Drivers front wing.

Just that I've got one on the front wing, I use it as a height indicator so I know how high I am with the roof rack, got tape round it at my height.

Wouldn't know how to wire an Ariel any way, what does the earth earth to (body?) and what does the other wire connect to (Ariel?)
 
I got an extending aerial from Halfords. Only 7 quid, I've got it mounted on my wing and so far I've picked up radio from Ireland, England and France. Not too bad :p

Don't really want a telescopic, will a cb ariel do cause I have one on the roof rack?:)
 
I spose the CB ariel will receive radio, better than a coathanger anyway:rolleyes:
 
A cb anntenna will receive some signal, but its not ideal. The lengths of a whip anntenna are a specific length that is matched to the wavelength of the middle frequency of the band it's designed to receive.

A full length whip for the FM band is about 0.8meters I think (I'm sure Wikipedia will give you the exact measurement). The alternative is a half length (40 cm) whip fitted onto a large flat ground plane (flat horizontal body panel, such as the roof or wing).

A cb antenna is longer than an FM antenna, because it is matched to the middle of the cb frequency band. It will give you some signal for your radio, but the reception won't be as good as a proper FM length anntenna would provide.

Hopefully any anntenna will be pre wired. But failing that, I think the standard for car radios is a 50ohm coax. Wired from the antenna to the connector on the back of the radio.

You should use coax all the ay back to the radio, and not just a signal wire, because the coax phase an earth shield around the signal wire to minimise interference and therefore give a better reception.

It is a telescopic but its not motorized. I just left it up and it looks like a normal whip but can be pushed down if I go green laning or whatever.
I asked the staff in maplins if a cb aerial could be used but they didn't have a clue and there was a much wider range of aerials in Halfords anyway

Thanks for that tech stuff

How come a telescopic ariel works whatever length you have it at, my base load CB ariel is about the same length as a telescopic one.

I have a piece of copper fuel pipe about six inches long on my old Saxo and it works a treat:)

Goin to have to try it then and see what happens;)

Yeah, very true. It does work to some extent, just not ideal. In older radios you'd experience more and more crackle the further away from ideal conditions you get, but modern systems have all manner of clever **** going on there to make the best of a bad signal, hence why a coat hanger works in most situations.

Mine don't crackle, just picks up the alternator if the earth is bad, only got MW and LW at the moment:rolleyes:

Yeah, like I say, the crackle is more a thing for older radios. But your symptoms (not having fm signal at all) wreak of crap signal from the anntenna.

Picking up engine noise is usually solved by fitting a suppressor on the power supply.

Solved on mine by cleaning the ariel earth but cleaning it etc was the final straw for the old telescopic mast and it broke soon after:(

Was thinking of a rubber duck but like the whip ariels:)

Did have a great signal from ariel and radio has no FM facility at all just has the two bands LW and MW so I couldn't pick up FM if I tried:)
