Last week I installed a Baby Loop on my roof 2m high and a long way from metal, at least 8 metres. It worked fine for a few days, then I started getting Motor Fail warnings. The PSU works fine and gives me 24 VDC at 3 amps. In debug mode when I drive the motor manually using the 9/3 8/2 an 7/1 buttons it is OK and the antenna opens and closes. I get around 400 mA load on the PSU with the motor in operation.
A couple of times I have been up to the roof and not really done much. The antenna works fine then the fault comes on again for no apparent reason. Straightened out the coaxial feed and motor cable and measured the SWR through a dummy load connected on the roof instead of the loop, so coaxial is OK. I am using a 1:1 choke balun at both ends of the coaxial. Have tried removing these but it is the same.
When I try to tune manually using * then enter frequency, it shows 30783kHz-7050kHz, then motor fail. I have never entered a frequency of 30783 so that is strange.
I see there was another thread earlier on this subject but it was not properly resolved.
As you know the antenna is not cheap so this is disappointing. Any help would be gratefully received.
