At home, I never use one. *Any amplified antenna also introduces a noise figure in addition to atmospheric and manmade noise. *Examining the spec sheet on the devices used in the active antennas construction will tell you the amount of noise you are introducing into the antenna system. So, of course, at home, I use the best/highest/length possible. It is relatively easy to find that an active antenna is NOT even in the same league as a 120 FT antenna mounted 30 FT or more in the air. Simple tune a weak station on the 120 FT antenna and then disconnect and find that you can't even receive the same signal of the active antenna (probably is there, but below the noise floor and unusable.) *Again, just a simple law of physics ... you can read any book on the subject and find it plainly stated ... however, like everyone else, I first had to find it out for myself, before I accepted it ... I'd just love to toss 30 FT of wire out a second story window and get every station on the other side of globe ... wouldn't we all? Regards, JS ....if I threw a 30ft wire out my second floor window the result will be a lousy ground connection... |

Hello! Introduction and a few questions
That was an old unsafe to use anymore 100 feet long extension cord.The
insulation was cracked and peeling off in a bunch of places. I have a book here about barb wire collecting.Some of that old antique barb wire is worth a lot of money. cuhulin |

And, noise pickup is acceptable? You have underground power? The were supposed to drop the powerlines in my neighborhood underground, then the economic collapse hit ... there is a transformer, somewhere around here, which causes noise, especially when raining. Power company came out and I pointed out the transformer to them. They said they would have it fixed ... but then, that also was before the economic collapse worsened/lengthened ... I am going to have the wife call 'em and complain, again ... and, probably again ... Regards, JS |

They need connectivity for their surveillance equipment. |
