Dual Polarity Combo Mesh Nets are the most versatile
electric net fence made. They are tall, have tighter standard
mesh with very tight bottom mesh, and can be operated as "hot
and cold" or "all hot" fences.
Country Net user testimonial
Polarity nets, animals are shocked when they touch two
adjacent wire strands with opposite polarity (one positive and
one negative) at the same time. The earth or ground is not used
or needed to complete the electrical circuit. Alternate strands
are separately connected together at the ends of the net so
that the netting fences can be operated either in Dual Polarity
mode or regular "all hot" mode.
Nets also have Combo Mesh with mostly standard 4"
x 6" mesh but with two extra non-conductive strands at
the bottom to make a finer and tighter 2" x 6" mesh
for a more effective fence with smaller animals and predators.
This smaller mesh size area is a barrier that tends to push
animals up into the electrified portion of the fence. However,
these extra strands do not leak any electric shock from the
fence or permit any short circuits.
