Re: The SULA antenna

Noted on the correct mast height specs ie 3m to bottom corner of antenna.
I will make up a mast extension and repeat the SW test . SULA vs JHG mag loop.
Busy with some work at the moment and WX raining. Thanks for your input Andrew.

Re: The SULA antenna

Hi Andrew I have tested the SULA vs MLA-30 and JHG amp mag loop. On SW the SULA is the best performer. On MW tested the SULA vs JHG amp mag loop The JHG loop is the best performer the SULA preamp is much noiser All tests done indoors. I would still like to repeat the SW tests outdoors ie SULA vs MLA...

Re: The SULA antenna

I will be trying the local one from Giga Tech as I will be using the SULA on SW.
My JHG amplified mag loop is very good on MW. The amp is similar to a UK design ( ALA1530)

Re: The SULA antenna

Thanks Andrew I have my own Amplified Magnetic Loop which works very well on MW and its powered by a 12v battery so I can use it to power the SULA preamp
