Active antennas
I am considering buying a Icom r75 and would like to get an active antenna
to go with it. my question is this Are the active antennas worth the money or should I stick with a wire antenna? Thanks for any input Steve |

Shortwave Listening (SWL) : Active Antenna ? -or- Wire Antenna ?
SD,
For Shortwave Listening (SWL) what you would spend on an Active Antenna; you could buy a good 'passive' Wire Antenna. * Your Location {Region} and Weather can be a Factor in your choice of Antennas. * The RF Environment {Noise} of your Location {Neighborhood} also can be a Factor in your choice of Antennas. 1 - Two Major Determining Factors would be : * The Size-of-the-Area {Space} that you have to put the Wire Antenna up in; and the relative noise of your location. - - - - - vice - - - - - * The Distance-Away-from the Home and other Sources of Noise that you could Locate the Active Antenna. 2 - Here are a few Good "Out-Side" 'passive' Wire Antennas for the Shortwave Listener (SWL) : {Sized - Big to Small} * Alpha Delta DX-Ultra Antenna http://www.universal-radio.com/catalog/sw_ant/3377.html * Antenna Supermarket Eavesdropper SWL Sloper Antenna http://www.universal-radio.com/catalog/sw_ant/0013.html * * Par Electronics EF-SWL Antenna - Rigged as a 15 Foot Vertical by 30 Foot Horizontal Inverted "L" {Low Noise} Antenna with Coax Cable feed-in-line. http://www.grove-ent.com/ANT8.html http://www.universal-radio.com/catalog/sw_ant/2205.html * RF Systems Mini-Windom Antenna http://www.universal-radio.com/catalog/sw_ant/3575.html 3 - Here are a few Good "Out-Side" Active Antennas for the Shortwave Listener (SWL) : {Priced - High to Moderate} * Dressler ARA60S Active Antenna http://www.universal-radio.com/catalog/sw_ant/4061.html * RF Systems DX-10 Professional Active Antenna http://www.universal-radio.com/catalog/sw_ant/2868.html * * McKay Dymek DA-100E Active Antenna http://www.universal-radio.com/catalog/sw_ant/0328.html * LF Engineering H-800 Skymatch Active Antenna http://www.grove-ent.com/ANT15.html * MFJ-1024 Active Antenna http://www.universal-radio.com/catalog/sw_ant/1132.html Most of these are considered to offer Full Spectrum Coverage of both the Medium-Wave and Shortwave Bands : 500 kHz - 30 MHz. FWIW - As time goes on you may wish to have both an Out-Side Wire Antenna and an Active Antenna as a "Pair" of Antennas to Choose from for a variety of Shortwave Listening (SWL) needs. iane ~ RHF |
Active antennas
While an external antenna, such as an Eavesdropper, would be the best
solution for you, an internal active antenna such as the Radio Shack amplified shortwave antenna is good too! "Stephen Drummonds" wrote in message ...

Thanks for any input Steve Active antennas can be reasonably good, but there is one tiny hitch: You need to isolate it from all the electrical and computer hash you'll generate in your house. Do not buy a cheap active antenna or you'll be sorry. It's actually easier to erect a random wire antenna and use it instead of an active antenna. That said, a well isolated loop antenna with an external power supply, isolated from the rest of the house, might be just what the doctor ordered for a small suburban lot. Loop antennas have the advantage of being able to null out local groundwave signals. However, if you have more than fifty feet of distance available to you, I suggest you look in to the random wire first. It's cheaper, and it just plain works... DE AB3A |
Active antennas (Thanks for info!)
Thanks to all who wrote and gave me some very good answers to my question.
I think I will go with the wire antenna for now also to the gentleman that asked what area I am from Im located in Alabama Thanks to all who responded!! Steve "Jake Brodsky" wrote in message ...

Thanks for any input Steve Steve: IF you live in a Very , low noise environment; - Or can move the active antenna out away from your home, Into a low noise environment, then I suggest messing around with this. Putting up an active antenna in a noisy environment will just .. Amplify the ambient noise as well as Shortwave Signals Suggest Just use a regular random wire, with a co-ax feed. Congratulations on th R-75 |

Steve,
PA0RDT-Mini-Whip {Active} Antenna - Inch-per-Inch - It Works ! http://groups.google.com/group/rec.r...c4666783b0a2f6 Shortwave Listening (SWL) "Receive-Only" Antennas - Away Is Better - Then Up ! - Or Is It ? http://groups.google.com/group/rec.r...75a10814862d1d ~ RHF |

David - The MFJ-1024 Active Antenna was on the list of Active Antennas that I provided. http://www.universal-radio.com/catalog/sw_ant/1132.html * For many who can not have a very 'visible' Antenna small Active Antennas like the MFJ-1024 do a very good job in letting them hear what they want to hear. * The only feature of the MFJ-1024 that I do not like is the Telescoping Whip Antenna. * * I would replace the short Whip Antenna with a solid CB Whip Antenna mounted on a piece of 21 Foot Top-Rail and 50 Foot of Coax Cable to get it away from the House and out-side Up-in-the-Air. * * Small Active Antennas like the MFJ-1024 some times can be used In-Side the Attic with a Pair of Perpendicular One-Metre Diamond Wire Loops. and that's my view from the far side of . . . the antenna wire - iane ~ RHF |

Thanks for any input Steve I have a Dymek Stoner DA100E active antenna, indoors. It works fine, doesn't take up much space, but a full size outdoor wire antenna provides stronger, louder reception of signals. A big wire antenna is cheaper, the active antenna is more convenient; take your choice. bob k5qwg |

They are omnidirectional and vertically polarised. These can be advantageous attributes sometimes. The more antennas the merrier. |
