The car already has 2 x TV antennas and 2 x TV antenna amplifiers (boosters)

The standard system is extremely well designed and engineered and works particularly well. You won't be able to do much at all to improve it.

Apart from mounting a steerable yagi antenna on a 10m pole on your vehicle roof :-)

If you suffer poor reception, it is due to low signal levels in your area. Drive to a different place!

2 antenna con = 2 yagi's

ontopic: @andyC, do you have original antenna's on car, if navi/tv comes as retrofit, maybe you are 2 antenna's short...try with a simple 10 inch wire on either antenna connector on tv module (inside pin), if you get a better reception, then have no antenna on car, just wires...

That would be tricky and would depend on the car. If it's an E46 then they are behind the rear bumper skin. On my X3, they are built into the rear quarterlight glass. Dunno about the 5 series or the X5.

What car have you?

I don't know what you are expecting out of the TV module - I found analogue TV was pretty poor whenever I wanted to use it, and a total waste of time with TV-in-Motion. DTT (Freeview) is better stationary but depends on whether there is current coverage, but again useless whilst moving. I have a Hybrid VM by the way

Will be interesting to see whether it significantly improves when we go fully digital in the next couple of years - assuming of course that the BMW Hybrid will cope with 8k mode

then bear in mind the TV antennas are built into the rear bumper

It would be worth checking that both antennas and both TV receivers are working properly.

Unplug both antennas from the video module (TV tuner)

Then connect each antenna, one at a time, to the first antenna socket.

Tune into a weak analogue station and note picture quality.

Then try both antennas on the 2nd antenna socket.

At the end compare notes: you should have tried 4 x combinations.

With a car standing still you can expect about the same reception levels from each antenna and from each tuner.

If one tuner is showing poor reception, replace the video module.
If one antenna is showing poor reception, check the antenna connections to the bumper antennas. This may mean removing the bumper and cleaning all connection points.

This is hugely country and TV station dependent!

I found analogue TV reception was excellent in my country, and TV-in-Motion was perfectly watchable.

But I was watching TV stations with strong signal on VHF-I and VHF-II, and driving around 20km to 40km distance from the main transmitter mast.

The UK only broadcasts analogue TV on UHF, and quality of mobile reception on UHF is nowhere near as good as VHF, due to the shorter wavelength of the radio signal and the susceptability to interference.

But then, if the UHF is broadcast from a mountain top and you are driving through strong signal areas on a flat plain with few buildings, then reception will be good. Driving through the center of London is a very different story...

So like I say: it varies hugely by country and by frequency!!
