Dick, I see you're getting some replies trickling in already.
Two feet won't do it I don't think my friend....not even close. In 1997 @ CY9AA (St. Paul's Island) we had a balloon supported 160m vertical using a very fine uninsulated wire (and I think maybe kite string too). I was not in charge of this part of the expedition (VE1PZ was our topband guy) but I am pretty sure we used a 4-5' - "rubber" balloon. (could've been latex or something similar) We eventually lost our balloons to sharp rocks, so lacking any other method or access to a store, hi) we blew up a few green garbage bags, (doublebagged) which surprisingly lasted a few hours or maybe more..where there's a will, there's a way. We were pretty loud in EU and elsewhere, right over salt water. I think Doug (VE1PZ) went to a specialty (welding?) store to get the gas. I have no idea what it was-pure helium I presume, but you can see the orange tank in one 24yr old photo here: http://www.uksmg.org/content/cy9photo.htm Good luck ! Mike VE9AA..ex cy9aa, cy0aa Greetings All I want to try a balloon supported Vertical for 160. Any advice on sources for balloons? Mylar material and diameters up to 2-feet would be my choice. 73.
