I recently read somewhere where, and please don't laugh, someone actually
used a metal slinky toy as an antenna in just your situation. He said that he simply let it drop out a window for DX'ing and when he was done, just pulled it back in. I've never heard of how successful it was, but it may be cheap and fun way to experiment. 73's, Todd KB3KNV |

I recently read somewhere where, and please don't laugh, someone actually
used a metal slinky toy as an antenna in just your situation. What's to laugh at? The Slinky-as-antenna concept has been around for a LONG time, and has many, many proponents in the SW and amateur realm. Do a search for 'slinky antenna' on google or your favorite engine, see how many hits you garner. I've experimented with Slinky antennas in the past, but more out of curiousity than outright need (I use a 75" sloper and a large horizontal loop 'skywire', about 200" a side, for my outdoor antennas) but they can be rewarding antennas. For about a year I had an indoor Slinky antenna 'loop' running around the ceiling in my room, all four walls. When storms or wind were howling outside, or in snowy conditions (blowing snow and sand can cause a LOT of static build-up on a longer wire antenna!) I could still do some rather nice listening without fear of frying my radios. Worked pretty well on my scanners, too. And you're right, it's cheap and it's fun! Linus |

The U.S. Navy used them for transmitting from ships in the 50's........hung
from the rigging vertical. "Macman" wrote in message ... I recently read somewhere where, and please don't laugh, someone actually used a metal slinky toy as an antenna in just your situation.

from the rigging vertical. Yeah, sure. Only if some ham was bootlegging. At that time, ham operation wasn't allowed on Navy vessels. Bill, K5BY |

check it out . I have the book somewhere and try to find it. It states it
was used by the Navy for transmitting military frequencies, not amateur. "WShoots1" wrote in message ...

The reason for my doubt is that, in the 1950s, I worked on Navy comm systems, in a factory and on some ships while working in shipyards. Vessels ranged from tugs, landing craft, and minesweepers to a cruiser. Bill, K5BY |

The book I am referring to was published about 1959, and dealt with variable
types of vertical antennas. I have recently moved and will be attempting to locate it in about 206 boxes of books. I am sorry if I have offended you, sir, it was not my intent.

You haven't offended me. In fact, I was probably too blunt. But I am very interested. Remember me and post what you find, whenever you finally get a chance to go through your books. I'll look for Subject: Slinky Navy Antenna. When I moved here 12 years ago, I downsized by a factor of 4, so I had to give up a lot of my books. (Sob!) That was my last move ever. At age 73, I can say that with assurance -- unless a hurricane or fire takes me out. G Anyhow, maybe in the meantime, I might find something on the Internet about slinky Navy antennas. All the vertical HF antennas I'd been aware of was the common 33-foot vertical, plus the discone-discage. Even the 2-3 Mhz tug boat rigs fed those 33-footers, using a VHF type of coax -- 4-inch copper pipe "shield" with a 1/4-inch copper tubing "center conductor." LOL Oh and I suggested to Navy design in Philly, in 1960, to turn part of the "sail" of a sub into an antenna embedded in fiberglass for HF, to overcome the problem of having to wait until the sal****er drained off the 33-foot vertical' insulator before transmitting. I underestand they did. Oh, and I was offered a GS-9 job then as reward for that and for a field test I'd conducted of an antenna multicoupler. (The latter had flaws.) I turned it down because my current employer then gave me an opportunity to go to work with big digital computers. Best wishes in your new abode, Bill, K5BY |
