Hi there - ive got a Sony ICF-7600GR shortwave radio and was looking at
a way to improve my reception (pick up more comms and stuff) - i was wondering if a longwire antenna made from Phono wire would do the job - and then just clip the phono onto the antenna with a crock clip ;-) Any ideas? Cheers {FireArm] |

Wire is wire... just don't overdo the length going to that portable or you'll possibly overload it, a common problem when trying to attach a longer antenna. dxAce Michigan USA http://www.iserv.net/~n8kdv/dxpage.htm |

Run some wire around the perimeter of the window held in place with
small suction cup hooks. The length isn't critical, but as DxAce said too much antenna and you will flood the receiver with signals. A wire antenna isn't particularly selective, and it will pick up all signals more or less equally. So Radio Havana will come in nice and strong, but so will static crashes and hash from a nearby computer or tv. Modern portable receivers are quite sensitive and they pick up a lot with just the built-in whip antenna. Unless you are inside a steel frame building that radio should hear lots of shortwave broadcasts and ham stations with just the whip. |

I found that on my Sony 7600 about 5 yards of longwire is about right.
73's Richard SO5GB, Warsaw "RHF" wrote in message ups.com... FireArm, Yes - Clipping a single piece of Phone Wire on to the Tip of the Whip Antenna will work. The better Idea may be InDoor Loop Antennas : Try taking a single piece of Phone Wire and form it into an Around-the-Ceiling Loop Antenna. You will create an InDoor Horizontal Loop Antenna between 32' - 44' long. Or taking a single piece of Phone Wire and form it into an On-the-Wall {Inverted} Delta Loop Antenna. You will create an InDoor Vertical Loop Antenna between 24' - 36' long. From where the two wire ends that form the Loop meet; Twist the two wire ends together to form a Twisted Pair of Wires to extend to the Radio. Connect the Two Ends of the Twisted Pair from the Loop Antenna to a 1/8" Mono-Plug. Plug the 1/8" Mono-Plug into the Radio's External Antenna Jack. iane ~ RHF . . . . . |

Cheers {FireArm] Many people have improved there reception somewhat doing exactly what you describe. The type of wire is not that important, but thin and flexible is easirr to work with. Many say that wrapping several turns of the wire around the antenna works better than clipping it on, others disagree with that. Experiemnt. Try a length of wire about 21' long for starters.

Cheers {FireArm} Overloaded means that the strongest signals you can normally receive will start appearing at several places on the dial besides in their correct location. There, they will wash over several freequencies above and below that. A classic case of "too much of a good thing". It's the weaker signals you are frequently after! You need a longer wire for picking up weaker signals - until it gets long enough (especially on small portables) to start "overloading" the front end of the tuner.
