Yes Mike, Lino is sending us all loopy!!!
The problem some of us are having are huge noise levels, due mainly to being in a suburban location.
With many of my neighbours now using huge plasma TV's (the guy right next door has a 60" mega sized set that draws as much current as a several vacuum cleaners!!) and those awful CFL light bulbs, the HF noise has risen to the point of being unbearable.
That coupled with the small backyard that does not allow for many of the longwire or dipole arrays to be put up made the decision to try a Wellbrook Loop an easy one.
The reason for the rotator is that it will enable the loop to be turned, helping to null out any sources of noise since the loop exhibits a figure of 8 directivity pattern.
Check out the details and polar plot of the ALA1530 here:

Presently I use an Off Center Fed Dipole antenna, which works fine on 7, 14 and 21Mhz with a transceiver and receives reasonably well through a tuner for SW listening.
The noise here makes HF listening very unpleasant and frustrating and when the neighbours turn on their plasma TV, apart from dimming all the lights in the street, it makes listening just about impossible. The company that generates the cities power has had to employ more people to shovel the coal into the furnace faster when the big plasma TV is turned on
Whilst not expecting miracles, the loop should pick up the same signals as the OCFD, but with the ability to null out some of the local noise sources.
Lino: I will be using some RG58 to start with, since that is already a spare run fed through the wall to outside. Eventually I will run some RG-213 outside but that will require a session with the impact drill and masonry bit!
