Group: What kind of antenna? (700' outdoor telco line)

Unzip and solder the phone line for a 1000' Beverage fastened with zip-ties to the shrubbery above the stream? (I doubt any neighbors would even notice the wire.)

Also, presuming he listens to LF or MF and has a need for a beverage. Finally, a Beverage is typically good for ONE direction only: north OR south, east OR west, not both. There IS a "two-wire" bi-directional beverage, but not for zip cord; it seems the two conductor Beverage must have a wider spacing (typically 10 inches), obviously much wider spacing than the zip cord has. |

Thanks for the info. If I want to try tropical band, the stream to the south lines up with Havana and Managua; have to calculate an optimal length... -j |
