The SLINKY has been a popular field day antenna for years. I use it here
suspended vertically penetrated by a vertically mounted telescoping
fiberglass fishing pole. Cost $1.88 + $8.00 plus $ $2.00 for RG-1744U
and a hand wired 4:1 balun

This comercial $40.00 slinky CLIFFDWELLER will load up and work with a
tranmitter: http://usa2way.homestead.com/CliffDweller.html

I made mine with a Wal Mart SLinky

It started with a slinky stretched accross the LR and DR I picked up
Eastern Med but a LOTTA NOISE from the house.

SLINKYS, originally used by military exsperimentally in Korea, are a
popular antenna for HAM field days :

He wants $40.00 Slinkys cost $1.88 at WALMART

I USED one...NOT A BALANCED PAIr like the cliffdweller. His picture
shows it used INSIDE his shack. He's got a balun in the PVC Tee
connecting the two slinkys and a SO 259 for your coax

HADDA get the antenna outside and isolate it with a balun and come in
with sheilded cable instead of the nekked hookup wire tot he raidio
when it was inside.

Instead of expensive coax you can use TV cable RG-58 and use the TV 300
ohm to 75 ohm adapter as a poor mans balun...many listeners dont notice
any difference between that and a home made 50 ohm balun.


All you ever wanted to know about slinky antennas---many URLs derivative

I made my balun on a 1.25" powdered iron core You could use the core
from a scrapped switching power supply from a computer. Wind a secondary
1/4th the no. of turns you estimate is on the primary

mine was 100 turns of magnet wire primary for antenna and ground.
The secondary 40 turns magnet wire
on top of that for RG-174 and braid to receiver

received briefly or weakly Ceylon and Singapore on it and routinely
Europe,Eastern Med and S. America

Hi there,
This topic, I'm sure has been covered before. My brother-in-law is about to
take a long sailing trip from NZ to USA as a passenger aboard a cargo ship.
He will be taking with him a Grundig YB 400 receiver. He had heard of other
sailors/passengers dangling an antenna out of their port hole window to tune
into radio stations on their SW receivers. He has asked me if I could make
something up for him to take away with him. The unit has a 3.5mm mono jack
as the ext. ant connector. The radio has a small reel of cable for the
external antenna. According to the user manual with the radio it indicates
coaxial cable as part of the antenna system with out mentioning cable
lengths. The tuning freq possible with this radio are FM 87.5 - 108 MHz, MW
520 - 1710 kHz, LW 144 - 353 kHz, SW 1711 - 30000 kHz & 3200 - 29700 kHz in
20 bands.
Any ideas for a portable antenna would be gratefully appreciated.

Thanks,
