I am thinking of putting a shortwave antenna wire in my attic but I am confused on the correct length of wire. Some sites have different ideas on this and a couple say the longer the better. Only reason thinking of the Attic is due to the wife not wanting a yard full of wires.

I currently have my kenwwod 440 running on an Antron 99 for 10-17 meters and it seems to receive pretty good on the shortwave freqs. Will I actually get a big improvement by constructing a shortwave wire or I am just wasting my time? I was surprised at what I could hear on the Antron and I am wondering if I am missing much more.

Thanks,

Does your wife make the house payments? Smiley

A wire in the attic will not be as good as what you have outside. Besides, it will probably pick up every bit of noise generated by the various household electronics.

A smoking section in a restaurant makes as much sense as a peeing section in a swimming pool.

Almost anything outside will usually work better than anything in the attic. Another thing you can try for the lower frequencies is to isolate the shield and connect only the center conductor of the coax to the receiver. This will allow the whole length of coax, as well as the Antron, to act as the antenna. It may provide some improvement *IF* it doesn't pick up too much noise.
