I've been playing with a MFJ loop for my second floor condo and I can say that loops are extremely sensitive to any close objects/surfaces. For instance, tuning changed significantly when I had mine laying on the roof vs. ~4ft above it (to the point where SWR was marginal on the lower part of 40m with the former). It was horizontal both times, too.
Also, loops are going to have more loss at the lower end of their design range due to physics. 15w may very well not be enough to make contacts depending on how it's designed, though band conditions also play a role. -Mooneer K6AQ On Thu, May 14, 2020 at 7:21 PM Phil Kane <k2...@kanafi.org> wrote: > > On 5/13/2020 12:42 PM, brianchapn...@rogers.com wrote: > > > Im thinking of a loop.
