...In Germany you can use a maximum braid length of 100m without a special licence. If 200m would be allowed, my vertical would be a 200m ;-) But with a special permission you can relatively easy go
Can a thin wire be suspended between two kites, 100m or more apart? The resulting catenary (Oberleitung?) should add considerably to the capacitance (extra ~480pF?) and raise the overall effective he
Hi all May I ask you to pay some attention on the three following issues related to balloon/kite aerials ? - using "high" altitude kites or balloons is often subject to a formal authorization (at lea
That is exactly what I was thinking. That way the balloon will stay above the feedpoint. Weedwhip (plastic) line would work great for the support cords (ropes) and double as good insulators. Add mode
Hi Paul, Tried that some 9 years ago. Did not work due to heavy detuning effects if wind speed varied slightly. What worked sufficiently was a pyramid guying at ~1/3 of the full length of the kite ro
Mal, One option is to use helium balloon/parafoil kites pretty sure UK amateur G4VG flies a 160m antenna this way, when no wind the balloons work fine, when wind picks up switches to more normal kite
HAM communications should NOT be reliable communications, Mal. Certanly for professional communications this is very funny idea. But we are about HAMing. This is PLAY, but it is a nice play:-) Regard
Mike, group, what about a "construction" as in the attached figure ? I will provide topload and keep the balloon position more stable. 73, Rik ON7YD - OR7T Mike WE0H/8 Mobile on my BlackBerry Attachm
Stefan Just one warning, I have used kite-supported aerials on 136 many times and you have to be careful what insulating material you have between the kite and the top of the wire. One day the kite w
I was thinking of a balloon supported inverted L. No doubt whatever antenna is used, adding a hat will up the ERP greatly. Mike WE0H/8 Mobile on my BlackBerry
You will need a really big balloon to support all these ropes and wires! Better yet, use several balloons so in case one breaks it can still remain airborne. The University of Hawaii ham club has a w
Jean-Louis, In UK 60m is the flying limit and 30m near an airport but I think you'd have to be seriously daft to fly a kite near an airport anyway. You can fly higher too.... for permission to exceed
Sounds good if one could ORDER wind when flying the KITE, too hit and miss for reliable communications. Another DREAM. I am still waiting for a two way Dream 9 QSO, why the delay!! Hire a helicopter
Hi All, Talking about & discussing kites, today there was an interesting article in my daily newspaper regarding a kite, the article is attached but quality may be a problem so I have transcribed the
On 73kHz I originally used nylon strimmer cord as the antenna insulator. Worked fine until one day I was testing using PSK (100% duty cycle, long transmission) with G4GVC and it was raining. The a
