2006 Defender 110 Td5 XS DCPU Zambezi Silver

Hi,

Appreciate this is an old post but I have just fitted one myself and have encountered a problem on the DAB side.

When I fit the supplied booster, the radio shows antenna problem on the screen. The DAB works but I cant do anything.

I’ve tried the booster unpowered, no connection to anything and it pops straight up. I plugged the old window one back in and no pop up.

The radio is a Kenwood DMX7722DABS, has anyone had similar?

An earlier post identified the same problem with the Nak splitter,

Hi all
Have just attempted to fit one of these wonderful aerials to my partners 110 which has a Pioneer DEH-S720DAB head unit. It was working with the little stick on the window unit - but not very many channels or good reception.
Since adding the new Nakatanenga antenna (via Brendon and 4x4 overland) I have an ‘Antenna Fault’ message which wont go away no matter how I try and configure the power/ no power to the unit.

I see that PJ2016 had a similar issue with the same head unit as I have but not sure how the issue was fixed .. any pointers ??

Just to follow up for those who are interested ...
The issue with the Pioneer radio was sorted with pressing the reset button under the removable face plate for 5 seconds - then not using the ‘splitter’ provided by Nakatanenga but one from Amazon with a single power connection.
Similar to this one - https://www.amazon.co.uk/LEADSIGN-Splitter...amp;sr=8-5
This works very well and gives up a wider range of stations with good reception.
The Naka one would not work with the radio and constantly caused an 'antenna fault’ warning.
Hope that helps others.

Thank you,

I must have missed that reading through the posts. I’ll try a different splitter like that.

You have to turn the aerial power off on the head unit. And then you power your Nak loom. Fitted mine a few weeks ago. Same headunit as you 👍🏻

Thanks for that Landy Andy, eventually found that option and once I turned it all was well.

Yes, there is a setting for that, which is a bit annoying as you can easily chose the wrong one by accident.

These Antennas make a good Xmas present if you don’t already have one, I’m very pleased with it.
I’ve had one a few years now, works well and is robust.

Ideal that it is always there, so it doesn’t need putting up and also life proof for off road, won’t get damaged green laning etc.
If you want the DAB on, you can just put it on whenever. TheThunder Rolls🇬🇧🇺🇸

Solved! There is a setting in the radio’s system that either powers the dab antenna or does not. As the nalatende has a booster the power is not needed, so in the system you need to set it to off. Works

Found it somewhere hidden on the internet in a Mazda forum hahaha.

I’m happy, I’ll try it tomorrow to test the reception.

Still happy

Hmmm... for some reason the radio does not remember the power off selection. It does remember all other stuff...?

Are you sure it’s retaining permanent 12v feed input? To the HU.
If not it could wipe settings, typically that menu will only come up when power has been completely cut.

So suggests either ground being missing or poor connection, less likely OR being ignition power fed only without permanent 12v TheThunder Rolls🇬🇧🇺🇸

Thanks, I'll check it this afternoon. Are the normal ISO connections and as the memory and all other used setting remain I was thinking all is ok....

I'll check it.
