Topband: Capacity Hat Wire Size

I have a 72 ft irrigation pipe vertical for 160m. It is much stronger that
your Spider pole. I use 16 ga wire for my 4 top hat wires. I'm not sure how
many top hat wires you have in mind, but with 4 wires, they also act as guy
wires at the top.
If you use 4 wires, the current would be divided equally, so I'm sure you
can get by with small gauge wire, perhaps 22 ga, although that seems small
to me. If the Spider pole is too flimsy for larger wire, you may have to
guy it more often.
The top hat wires need be as horizontal as possible, but on flat land, mine
are pulled away from the vertical as far possible which is about 100 ft in
each direction for me. You can only do what you can, but it will work!
HNY & GL,
PS, I see that the A70X operation is on 160m. For a rare IOTA, and to work
the world, that is the last band they should be on. But I guess the guys
are having fun...
