Ah yes! If it's not the latest and last edition, then you should get one.

On Thu,
Thank you everyone who replied. The consensus was that sloping ground will
not matter much.
I was discussing with Tree that I may have the opportunity to put up a
similar, same direction, but temporary Beverage on the opposite side of the
hill which slopes in the opposite direction to compare. The
Same here, 570’ W/E with 80ft drop and ~8ft high in a hedge works well in both
directions.

My E/W Beverate (bi directional - brute force - transformers on each end

Works fine uphill.

What may be more destructive is a slow velocity factor in the insulated
wire. There is no way to estimate that, you just have to measure it. If
the VF is low, then you get into the same kind of problems

Hi Guy,
Good topic.
The losses as a reversible beverage would far exceed those used as a
balanced feedline, because of the balance partly cancelling fields in the
dielectric between them.
Slow wave structures are more common in microwave. Anything that increases
capacitance or inductance
Yeah, so he says when the wire is new. There is an ASSUMPTION that stuff
retains characteristic at RF over time when it was only designed for audio.
Have you ever noticed how pungent that stuff smells when you first pull it

I am preparing to install a reversible Beverage antenna, using 450 Ohm
ladderline. All of the components are from DX Engineering. The maximum
length I could fit on my property was 480ft. This would be the first of my
receive antennas for my first venture into 160 and 80M.
Here is my concern.
Wayne,
That's what mine does with the same components.
Works fine.
