Both DAB and FM are loosing radio reception, on DAB it's long periods of silence, some reception, sometimes some static, then silence...On FM it's just static and occasional reception.

It sounds like or acts like the arial has become disconnected. Anyone know where the arial is?

John- We need to know where you are, whether you are in built-up areas or countryside when you lose reception.
Radio wave propagation is very dependent on terrain, elevation and as the frequencies get ever higher, the weather and humidity conditions.
Think of it like sound waves, when you close a door, you lose all the high notes of music playing in the next room, the bass rumbles through it. It is similar for radio waves, longer frequencies can travel around the world bouncing off the ionosphere, but mobile 'phone reception use gigahertz frequencies - they can be blocked by tall buildings or other objects.

The other factor is that digital reception is either over the cut-off threshold or it's not, either fully on or completely off. With analogue transmissions such as FM and AM, you get increasing amounts of interference, but never completely lose the signal until out of range.

Add to this patchy coverage of digital and FM signals throughout the UK and you begin to see the extent of the problem. If you do regular long-distance trips, you may be better off sticking with AM stations if you want to maintain continuity of programme content at the cost of less fidelity. As with most things, it's a compromise, function over form.

All the best, Tony. (ex tv engineer)

Hi Tony, I live in the country (Bedford) but no matter where I drive, London, or past a field of sheep the reception is non existent, this is a recent problem, the radio reception has been fine for the last 4 years so I feel like something has come loose.

John- sounds like you have an aerial connection problem or the front-end of your receiver has sustained damage or has failed. Maybe you have been through a thunderstorm and a nearby lightning strike has fried the aerial pre-amplifier. If you've been through a car wash and the aerial has been twisted/bent or kids have been playing with it, that may be your issue.

If you have an acquaintance with a similar Nissan or similar looking aerial, try theirs before going to a stealer, most of them just unscrew from the base. If not, and it's your head-end be prepared for some very large bills for a replacement HU.
