I know little about active antennae except that if you absolutely *must*
use one, use a loop. -- Gregg t3h g33k "Ratings are for transistors....tubes have guidelines" http://geek.scorpiorising.ca |

I have a Grundig Rossini from about 1962 and I was wondering if anyone has suggestions on where to buy or how to build a good power antenna for the short-wave radio. This may give you some ideas. I understand the car is optional. http://www.miata.net/garage/power_antenna_repair.html mike |

I'm assuming that this is a home table radio, yes? If so, such SW sets are not that fussy about antennas. A random length of wire a few tens of feet works well. But if that option is out, people have successfully tapped their phone line for SW reception. The phone line usually is strung along poles for thousands of feet in the air, and will intercept SW signals. Unless you live in a city with everything underground. Connect a capacitor of about 500pF to 1000pF with a voltage rating at least 1KV (phone lines can have 90VAC when the phone is ringing, and transient spikes) to the antenna terminal and one side of the phone line. This size cap should pass the SW signals but not anything in the audio range. |
