Those are pretty sophisticated balloons. Bet those are similar to the
aerostats the US uses around the Gulf of Mexico for surveillance purposes.
Those are tethered and go up thousands of feet and are marked on our
aeronautical charts. Prices must be high on those, out of the limits of the
average ham here. hi

Yeah, but not too horrible. See price list at:

My guess(tm) on the weight of a 1/4 wave 160 meter monopole was 464
grams without the weight of the balloon, insulators, and whatever else
might be needed. Looking at the chart, I could get a "Skyhook" model,
that would lift 800 grams with no wind, for $760 excluding VAT, duty,
and shipping. You decide if having the loudest signal on 160 meters
is worth the expense.
