Powerline
Does anyone know where I can purchase a powerline antenna? These used to
be very plentiful. They seem to be very hard to find these days though. Could anyone point me in the proper direction? |

Perhaps because they were marketing gimmics that never really worked? Could anyone point me in the proper direction? In the rip-off section next to the snake-oil? |

Powerline
These never worked very well. It is another gimmick to make people spend
their money. For a local inside antenna, nothing beats a simple pair of rabbit ears. -- Greetings, Jerry Greenberg GLG Technologies GLG ========================================= WebPage http://www.zoom-one.com Electronics http://www.zoom-one.com/electron.htm ========================================= "manaen" wrote in message news Does anyone know where I can purchase a powerline antenna?

Uhm that's not entirely true I am *not talking about the plug your tv into the wall outlet type of powerline antenna. I am talking about the type of antenna that you could hook up to a powerline and examine pn pg ng individually while having your receiver hooked into an outlet. It may or may not have some attenuation switches as well to keep you from blowing the front end of your receiver up. I am well aware of the limitations surrounding powerlines. I would be using this for experimentation. The powerline antenna would primarily be for the protecton of the receiver connected to the outlet. I really don't care if there is static. There used to be a few companies that sold such boxes, but i have not been able to find them. I appreciate the help everyone has given though. |

Our local, small town power company just uses cheap AM radios that have a signal strength meter to look for noisy power lines, bad insulators and such. -- Best Regards, Daniel Sofie Electronics Supply & Repair - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "manaen" wrote in message news On Wed, 18 Feb 2004 21:21:45 +0000, James Sweet wrote: "manaen" wrote in message news Does anyone know where I can purchase a powerline antenna?

That is an interesting solution for stuff that radiates out into freespace. I am going to have to go dig up an old am radio and check it out. What I am really interested in looking at is the carrier current communications that are on the line and not radiating out into freespace (I know no matter how small a signal on the line is there probably are some freespace emanations). Guess I need a box, with a powerline input and bnc output that blocks AC voltage, DC voltage, switches between PG PN NG and can attenuate an rf signal from 10 to 30 dbm. Almost forgot, a 60hz comb notch filter would be nice as well. I could "hack" together a solution but I am pretty sure others have done this already. |
