Definitely in the United States, anyway. For a temporary setup (i.e a weekend), you would at least have to notify the FAA. They may or may not give permission, depending on your location in relation to airport and heliports. Longer setups would probably require a lot of bureaucracy. I would guess the U.K. has similar requirements. -- ================== Remove the "x" from my email address Jerry, AI0K ================== |

Not may, but will, and most countries also regulate such. In the USA, under Title 14, Part 101 it says that moored ballons may not operate more than 500 feet above the surface of the earth or within 5 miles of the boundary of any airport. It further says that moored ballons may not be operated more than 150 feet above the surface of the earth without 24 hours prior notification to the nearest FAA ATC facility of all the details of the planned flight. I doubt the rules are much different anywhere in the 1st world. -- Jim Pennino |

I doubt the rules are much different anywhere in the 1st world. The UK certainly used to have a permanent mast height limit of something like only 40 feet within 2 miles of an airfield. There's also a general limit on the height of flying kites (unrelated to amateur radio) of something like 150 or 200 feet (Google required to check). Reminds me of an event from the mid 80's, NC. Late Sunday afternoons our Civil Air Patrol squadron flew a route over seven lakes around Raleigh, NC, looking for stranded boaters. We had radio contact with the local Coast Guard Reserve units on each of the lakes, and would direct them to someone whom we thought was in trouble. Of course, the CGR did their part by notifying boaters we would be checking, and to watch for us if they were in trouble. I was flying as an observer this time (we had two observers - one on each side of the plane so the pilot could concentrate on flying). Going over one lake at about 1,000 feet above ground level, I had to make an abrupt turn. There was a guy in a para-sail being towed by a speedboat - about 200 feet ABOVE us. He was so small (and we weren't expecting anything over us - air traffic control had nothing on radar) that we didn't see him until almost too late. Fortunately, we missed him (and his tow rope). Looking back, he was softly floating towards the water. I don't think ATC believed us and don't know if the FAA did anything about it. But I'll bet that guy didn't soar that high again! -- ================== Remove the "x" from my email address Jerry, AI0K ================== |

For grins and giggles I checked the CAA web site and found that you need to file a written application to fly a moored balloon at or above 60 M. So much for a 1/4 wave antenna at 136 kHz, but 59 M would be better than nothing. -- Jim Pennino |
