OK. I'm hoping that needed antenna wankery can be done from the
ground, like a yagi, so we don't need to loft anything big.

Well, if we are not careful the tether uses up a lot of that. At 1000
ft, even something as light as 7 grams/foot uses up all your payload.
(For comparison, 14 gauge zipcord weighs about twice that).
I'm not worried about anchors, like Meredith points out, heavy stuff
is cheap and available.
