WARNINGS AND DISCLAIMERS

Connecting unapproved devices to phone lines may be illegal in your area.
Telephone lines present a potential shock hazard. Do not use this antenna
for transmitting. Use at your own risk.


INTRODUCTION

This article describes how to use a phone line as a shortwave receiving
antenna. Performance will vary depending on the kind of phone line you
have. Overhead lines usually make okay antennas, while underground lines
| usually don't. Phone lines carrying DSL service may be unsuitable because
| DSL operates over a wide spectrum. A phone line antenna will generally
pick up more power line noise than a dedicated antenna, so don't expect to
| use it for DX work. Nevertheless, I found that it outperformed the
| telescopic whip antennas built into many portables.

A reader sent in this suggestion: If you're concerned about connecting
the phone line directly to the receiver, try wrapping the phone cord
several times around the receiver's telescopic whip antenna instead.
Performance may not be as good as a direct connection, but it will
probably be better than the whip antenna by itself.

Someone else wrote asking about lightning protection. I haven't thought
much about it because thunderstorms are rare in my area. Most phone lines
have lightning arrestors on them where they enter the house, but the
lightning arrestors may pass enough energy during a lightning strike
damage a receiver. My suggestion is to disconnect the antenna when not in
use if you experience frequent thunderstorms.
