I decided to go dig out the BMW manual on communication and indeed the rod aerial is involved in FM, but only as it seems posted earlier on higher level systems and in the FM 87.5 to 108 range.
Perhaps that explains why it makes no difference to my reception (basic set up) but does to others.
BMW aerial systems
The radio aerials for AM/FM are described in the following.
The other aerials are described in the respective
chapters.
The E85 features the following aerial systems:
- Rod aerial for AM/FM
- FM aerial in rear bumper
- GPS aerial for navigation system
Rod aerial
The rod aerial is a common part from the E46 convertible. The aerial is designed for AM/FM
reception and additionally features an integrated telephone aerial.
The rod aerial is mounted on the rear left side panel. The aerial amplifier is screwed to the
aerial from below.
The rod aerial consists of the aerial rod, aerial head and aerial base with integrated aerial
amplifier.
Aerial diversity
The E85 features aerial diversity for the higher grade radios. Aerial diversity comprises following
components:
- Rod aerial with amplifier
- FM aerial in bumper
- FM aerial amplifier
- Aerial diversity
The aerial amplifier and aerial diversity are fitted in the rear left of the luggage compartment.
The second FM aerial is located on the rear left in the bumper.
Components
The aerial diversity system includes the rod aerial with amplifier and the FM aerial in the
bumper.
Rod aerial
The rod aerial is identical to that of the E46 convertible. The rod aerial is designed for the
following wavebands:
• AM 522 kHz - 1710 kHz
• FM 87.5 MHz - 108 MHz
FM aerial in bumper
The FM aerial consists of a 73 cm long
line. The FM aerial is mounted in the
bumper on adjustable clips. The FM
aerial is adapted precisely to the vehicle.
For this reason, no
changes must be made to the aerial.
The FM aerial is connected to an aerial
amplifier.
Aerial diversity
In the E85, 2 physical aerials are connected to the radio aerial diversity, i.e. the rod aerial
and the aerial in the bumper. The aerial diversity function switches over to another aerial as
soon as the system undershoots a defined threshold. Changeover takes place in such a
way that no interruption can be heard. Depending on the reception situation, reception on
both aerials simultaneously is also possible.
I can email the entire document to anyone interested or more technical on comms than me complete with illustrations, wiring diagrams, etc.. It incudes details on how the following can be tested at the radio:
Frequency of Station
Station Identifier being received
Field Strength
Quality of Station
RDS identifier

Interesting read this thread and interesting idea to change the size of the aerial. Always thought the OWM aerial was a bit gangly.
No idea what the mango aerial is, instead, will the Honda "stubby" from the S2000 fit the car? Does anyone know if the thread pattern the correct size?

The Honda S2000 antenna will fit the Z4. One of the members on this forum has one on his.DannyBoy said:
I recently got an S2000 aerial from eBay thinking it would look spot on, but it doesn't.... 
Granted, the actual thread is the same and the thread length is fine, but the base of the Honda aerial is much wider than that of the OEM one and IMO it looks daft due to the difference in the base size/taper.... Or am I doing something wrong and need to unscrew more of the aerial base on the car....?
I had an aftermarket shorty aerial on my old MINI Cooper S and the base of that matched the car's mount perfectly. I'll try and find another aftermarket one after being rather disappointed with the Honda version...
