Title: Elite Aerials
Post by: Mr Skrunts on 04 July 2010, 13:54:21
Just out of interest, I was looking at the 2 Elites Josh has for sale, why is the Estate aerial longer.

Coz the signal has further to go on an estate than a saloon... ::) ::)

Noticed that difference between our saloon & estate.

Believe saloon aerial is for phone only - radio aerial is "built" into heated rear screen.  Think that estate aerial caters for both phone and radio.

as above, Saloons get their radio signal from the rear window, Ariel is only for GSM phones.

Estate gets it radio signal from the Ariel, hence its longer  :y

The stub for the phone on saloons is pretty dire tbh, it's only unity gain so when you take into account the losses in the cabling (it goes through three joins to get to the handset / head unit) it's barely better than using a built in antenna except that you've got it outside with a decent ground plane.

Even the estate aerial is flawed, while it translates to a 1/4wave colinear it loses the vast majority of it's possible 3db gain due to being at the wrong angle.

Still, could be worse, could be one of those tacky shark fins!

Most common vehicle aerials are in the form of a 1/4 wave antenna, so as the frequency gets higher, ie Cell Phones, the wavelength gets shorter.

I think one of the problems on later cars is the need to have a dual band / triple band antenna, an area where one size does not fit all!  ;D

Thought all the sat nav was disk based.

GPS signal is obtained by the ariel base, not the ariel itself. No data is transmitted maps are on the disc

Ignore me I am tired, just realised the idea of sat nav is to COMMUNICATE with the sat nav, hence needing an aerial.  :-[ :-X :-/
