I had a sloper version of this antenna about 15 years ago for
listening purposes. Excellent reception, and built like a tank.

I wonder what the performance difference would be between the inverted
'V' and the 'Sloper?' In light of your comment below, the end-fed
sloper might be a better choice easthetically.

It's pretty visible -- not exactly a stealthy antenna, but works
awfully well.

That's good to know. I suppose the antenna element insulation is
black not gray. I wonder if there's any way to change that. I
suppose a latex-based paint would work to change the color to
something less obtrusive until it pealed off. Any thoughts.

Thank you for sharing your first hand experience with Alpha-Delta
products. Much appreciated.

I don't know whether there would be a performance difference that you
could hear, but the sloper is basically one half of the dipole you've
ordered, and fed from the end. It would be more dependant on having a
good ground to work against. The dipole doesn't need a ground
connection.

It's heavy wire with black insulation, plus there are spacers between
the dipole elements, plus there are coils that have a white round form
wrapped with wire. I suppose you could spray paint it all sky blue, I
dunno.

Still, it's all the different elements that make it work well at
different frequencies, versus the single resonant frequency of a
simple dipole of only one length.
