Does anyone know or familiar with radio shack's amplified antenna for shortwave radio? It's a small black square box with rf gain and tuning knobs along with on/off switch and A & B bands. Question is I just bought one of these used and it didn't come with any plugs but it has an antenna and radio jacks/plugs on the side along with the 9v socket but am curious how these hook up to a shortwave radio? I have two realistic shortwave radio's and all they have on the back is the basic flathead screwdriver type screws for positive and negative for one antenna jack and the other is the pl259 antenna jack. Just wondering how I'm supposed to run the jacks from the amplified antenna to the radio's? |

Is it item number 20-280? I've got one and it works pretty well with my DX-392. According to faxback document # 21369 the cable that comes with the unit is NP Part # 11108990. It's just a two conductor cable with mono 1/8" phono plugs on each end. The center conductor is the signal and the outer is the ground or shield. For your particular situation you could buy adapters to make it work with the radio that has the pl259, and make up a custom cable for the radio with the screw terminals. Check what's available at your Radio Shack so you can use the fewest adapters. To make the cable buy a 1/8" phono plug and use a convenient length of 2 conductor wire. Connect the wires to the plug and then to the screw terminals. If the screw terminals are labeled you'd want the center condutor to the antenna screw and the shield to the ground screw. If they aren't labeled then try them both ways and use which works best. You could also buy a matching transformer to fit the screw terminals and adapters to interface with the female F connector on the matching transformer. |

Hey Racer X, I tried that a little after I posted this and it worked out fairly well. Noticed a difference in the signals that pulled them in better. Thanks for the input!!! |

Sure - glad to help. If you really want to hear some signals then hook an antenna to the antenna jack of the amplifier. I've connected it to my 11m dipole in the attic and found it worked extremely well. It also worked well with my A99. |
