Thank you Robert, for your help.

Yes I have tried to move the servo with a battery and it works fine in direct and reverse mode. So the PSU must be wrong. I am in contact with my distributor to get a new one.

Thanks again for your help Robert.

Hello Jose

The first 24v 1.0Amp AC Adapter I received with my baby loop was found to be faulty, the second exactly the same as the first but a replacement known to function with a baby loop has so far allowed my baby loop to function.

Both adapters were Chinese manufacture.

For your problem if you have investigated all issues that might arise from the loop installation between the ATU to the junction box on box the loop and can find no clear issue then you can suspect the PSU has become faulty.

I have before stepped the loop motor manually from a 12v battery without connection to the ATU to confirmed the loop operation.

I have also successfully run the ATU and the loop motor with a AC adapter rated 15v 500mA also made in China but with a feel of better quality than the items supplied with my loop.

Jose your PSU may have become faulty and if you can investigate and confirm no obvious issue with the loop or installation and with a different PSU then if your loop is still in guarantee then your supplier should be asked to provide a replacement.

Good luck

After reading your comments about the power supply, I have reviewed mine and surprisingly it is 24 volts 0,5 A. My Baby Loop has been working fine but now I have experienced a lot of problems from time to time and after running the Auto Detect procedure, the ATU is not able to recognize the Baby Loop and I get a Unknown Antenna Saved! message.

I wonder if the limited current of my psu could be the cause of these problems. I have attached a photo of the psu box. This psu was received with the Baby Loop from your distributor in my country. You can see very clear on the foto 24 Vdc 0.5 A. ???? If 1 A is not enough, imagine 0.5 A!!! Any help from your part will be welcome.

Once more hello everybody from Verona

to stop all rumors concerning the power supplies of our Loop Antennas, we would like to add the following explanation to our mail from yesterday which apparently led to more lack of clarity than to clearing up what’s on.

All Loop Antenna’s actuators consume at the very beginning of their motion (we are speaking of a fragment of a second) a somewhat higher current than 1 Amp. Over many years we had a high quality product of power supply which was easily able to cope with that peak at the motor start.

Then suddenly and unexpected, we were caught by surprise of some power supply failures during our factory tests and a closer examination proved, that their quality dropped remarkably from one batch to the other.

We quickly decided to change our provider of the power supplies and, to avoid a comparable surprise for all future, we decided for that stronger model of 24V / 2A .

Owners of later antenna-generations than mid 2018 are definitely delivered with the 2 Amp power supplies.

And all owners of earlier Loop generations using the reliable, robust 1 Amp power supply just use their antenna as they are used to, you don’t have to expect any problems with the ATU 2.0, nor their antenna motor.

Our distributors are informed and also aware of the history.

Mine is also delivered brand-new with 24V/1A power supply from the german distributor. Maybe that´s a problem why i have unstable SWR and the actuator or ATU is doing crazy things sometimes (restart, lost actuator-position)?

Hello everybody,

as the producers of Ciro Mazzoni Loop Antennas, we are somehow surprised to read, that brand-new Loops are delivered with a 24V/1A power supplies. Our original power supplies have 24V/2A.

We would really like to know from You, from which distributor You bought the antenna with this kind of power supply included. Actually they are not strong enough to operate the Loop’s actuator, especially if longer motor cables are in use.

Only to the UK we deliver the antennas without a power supply, because from Italy we can only provide „European“ plugs + the additional adaptors. In our British distributor’s opinion that was not an attractive solution and we agreed upon the policy to let him add an original British power supply to the package.

We were not aware of the fact, that they are only 24V/1A models and we are very sorry for the issues that finally our customers are facing.

We are getting in touch with the distributor to clear that up.

Hi joohno

Thanks for your reply apologies for delay in getting back.

As I mentioned I contacted the supplier with the same info I posted and had a swift response that the AC adaptor was suspected to be faulty and a replacement was promptly dispatched.

I got around to testing it yesterday and the loop functions as per the Ciro setup and operation instructions.

It would seem likely you also have a faulty psu and it will need to be replaced.

The psu type that are dispatched with the loop are rated 24V 1.0A DC and it does look likely that these are coming out of the manufacturer without proper quality control.

Maybe in the first instance you can also obtain a replacement from your loop supplier before going for an up rated 2A type as you may find that operating your loop on a psu that is rated higher may mask a different issue and might even invalidate the warranty. Just a thought.

I have the same problem, got the loop one day ago and the ATU shuts down when the motor runs on the fast setting. Operating the medium and slow setting is fine. I don’t think the power supply is supplying enough current. I have ordered a 2 amp power supply to see if it solves the problem.
