Jim, This is why I got involved with TACMO and the C-130 with 30,000 ft of antenna hanging out of it.
The Navy had installed a pod on the end of the wire to settle it down for open ended wire blowing in the wind at 300 mph it would flap around and modulate the VLF signal. Well one day they drug one of these pods thru a ship. Really upset a few...well a lot of sailors. So they put a altemeter in the pod with TX to let the crew know where the end was. I had to design a dedicated receiver to receive this. The only problem they would not tell me the exact freq due to it being classified. They gave me about a 5 MHz spread. Was a fun project. 73, ron, n9ee/r >From: Jim Brown <[EMAIL PROTECTED]> >Date: 2007/09/01 Sat PM 03:10:50 CDT >To: [email protected] >Subject: RE: [Repeater-Builder] Re: Duplexers > >On the E-4 aircraft we delivered to the Air Force, the wire was about 1/4 inch >at the aircraft end and tapered down to around 1/8 inch at the drogue at the >far end. (to keep the wire from whipping around in the slipstream). We >could never deploy the wire over the US, but had to go down to the closed >airspace south of Eglin AFB in the gulf to let the wire out. Can you imagine >what would happen to the power distribution system over land if you had to cut >the wire?  The wire was spiral wrapped ribbon and I don't know what the >core looked like>What size wire does it take to be self supporting at that >length?<BR><BR>'JK > >--- In [email protected], Ron Wright <[EMAIL PROTECTED]> wrote: >> >>... a C130 aircraft with 30,000 ft of wire hung out the back... > > > > Luggage?
