Where could I find Mini-Slinkys?
"RHF" wrote in message om... SR, Consider a simple-to-make Dual Slinky Dipole Antenna using two "Mini-Slinkys" Stretched-Out Horizontally; that is fed with 300 Ohm "TV" Twin Lead and connected to your Radio via the HI-Z (500 Ohm) Terminals. . NOTE: If you are using a 'portable' Shortwave Radio that uses an 1/8" Mono-Plug for an External Antenna Input. Then use a "300 to 75 Ohm 1/8" Mini-Plug Adapter" between the Antenna and the Radio. The 1/8" Mini-Plug Adapter to functions as an interface (Matching Transformer) for External SWL Antenna Signal to any 'portable' Radio that uses 1/8" Mono-Jack Input. The Twin Lead is connected to the two 300 Ohm Screw Terminals and the 1/8" Mono-Plug is plugged into the Radio. RadioShack Catalog #: 15-1148 R/S-CAT= http://tinyurl.com/2k2eu .

You Can Hear Forever and Beyond - The Beyond ! . . = = = "S R" wrote in message = = = ... I want to build an antenna for my shortwave radio. I live in an apartment. So it would have to be something I could put near the window. No longer then 3 feet. My idea is having 2 wires in a coil. Wrapped around PVC tubing on each end. It would look like the letter T. ( I am not sure which size of tubing to use). I am not sure how many feet of wire. Which type of wire. Should the wire be shield or not shield. If not shield, then when I wrap the wire, can it touch itself in the turn or must it be spaced apart? Then comes the end of the two wires. What do I use to solder to then plug into my portable radio? And is their a way I could make a tuner and have the wires connected to that first then to the radio? Thanks. 73 . |
