You might be surprised! - Steve - That is all very true. Three Different Noise "Sense" Antennas To Use For Noise Cancelling Antennas With An Antenna Phaser. Noise "Sense" Antenna # 1 - Short Vertical Antenna : The short 15 Foot Vertical Antenna is a good 'starting-point' : Since a Vertical Antenna should 'Sense' equally in all directions {omni-directional} from all noise sources that surround it. Both the MFJ and Timewave-JPS Boxes have a Noise Antenna "Gain" Adjustment so hopefully 15 Feet will be in the useful Range of this Gain Control. Otherwise, I will have to shorten it down to 5 Feet and try again. But, if I do shorten it down to 5 Feet : I still want the Top-End to be at about 15 Feet above the surface of the ground; meaning that part of the Coax Cable will also be part of the Vertical-Up-Leg. Noise "Sense" Antenna # 1S - Shorter Vertical Antenna Five Feet (5') Vertical Noise {Sense} Antenna o - 15 Feet above the ground l l F ll ll ll ll===========================P- Ground Level 'o' =End Insulator for Rigging Rope 'l' = 5 Foot Vertical Antenna Element using the Center Conductor and Inner Insulator of the Coax Cable. 'F' = Snap-On Ferrite Bead placed where the Antenna Element begins and the Outer-Shield Ends. 'll' and '=' = 45 Feet of Coax Cable feed-in-line 'P-' = PL-359 Plug to connect to the Noise Cancelling Combiner/Phaser. Noise "Sense" Antenna # 2 - Short Dipole Antenna Beyond the 15 Foot Vertical Antenna; I have also though of trying a Short 6-Foot Tip-to-Tip Dipole Antenna mounted on a 10 Foot piece of PVC Pipe and directly wired to a Coax Cable feed-in-line. Manually position the Dipole Antenna one-time for the Best Noise Pick-up and Cancellation. Noise "Sense" Antenna # 3 - One-Metre Loop Antenna Next might come a single-turn One-Metre Loop Antenna; again mounted on a 10 Foot piece of PVC Pipe and directly Wired to a Coax Cable feed-in-line. Manually position the Loop Antenna one-time for the Best Noise Pick-up and Cancellation. ~ RHF |

Yes for a general One Whip {Vertical} Antenna "Fits" many 'possible' Noise Source Needs - When the Location and Direction of the Noise Source is Not Known. The Whip {Vertical} Antenna will in-fact collect all signals equally and be very effective for most local Noise Cancelling uses. * This would be a Two Sigma [95%] solution to the vast majority of Home Radio Shack and/or Amateur Radio Station needs for 'local' Noise Reduction {Cancellation}. The Whip {Vertical} Antenna is a One-Size-Fits-All solution for a Simple and Practical {Cost Effective} Noise Antenna and is very easy for the End-User to use and get good results. KISAP - Keep It Simple And Practical When the Location and Direction of the 'local' Noise Source is Known; or when the Noise is Severe : Then a more directional Noise Source Antenna may be used to 'pin-point' the Source of the Noise and Optimize the Noise Cancellation Totally and Completely : In these cases a Dipole Antenna or Loop Antenna can be used to better Focus in on the Noise Source and Tune It Out; to the exclusion of other Noise Sources not in the same direction. * This would be a Three Sigma [99.73%] solution to the small number of Home Radio Shack and/or Amateur Radio Station needs for complete elimination of 'local' Noise is the objective. The Dipole and Loop Antennas are not a One-Size-Fits-All Solution : not simple to implement; not always practical to use; they cost more; and are more dificult for the End-User to use; but when done right can yield super results. * ITALOWTGIR - It Takes A Lot Of Work To Get It Right. Hence - Start with the Whip or Vertical Antenna and build on your personal experience until you are satisfied with your Noise Reduction {Cancellation} efforts to optimize your Radio Listening and Enjoyment. ~ RHF |

BpnJ - Do you have either -or- Used Either ? ~ RHF As I mentioned in earlier post (did you not receive it?) I have the 1026, and it works pretty well. Here is the text: My MFJ-1026 works very well for some kinds of noise, with two rather dissimilar external antennas attached. It gets rid of most of the noise that I hoped it would, that is, the continuous static and droning kinds of things (only one noise source at a time, however). It could probably get rid of lightining crashes and sporadic noise as well, but in practice the knob-twiddling required takes a tiny bit too long for it to be effective; ANL and NB work better for those sources. There is some minor internal diddling that must be done, explained in the manual, depending on your antenna configuration, but it is very easy and quickly accomplished. Some people install a switch to reverse the main and accessory antennas, and it is too bad that MFJ have not simply provided one. I will probably do this on mine eventually. There are plans for this on the web, IIRC, another very simple mod. This unit also attenuates MW, especially at the low end; there is a specific component inside that can simply be crushed to eliminate this attenuation if MW is high on your list of uses for this device. In fact, some like it just for that reason, because it is VERY effective at nulling strong stations so that weak ones can be heard underneath. I have tried this on several occasions, and have been astonished at how well it works. I would get one again (maybe even two in tandem if two sources of noise are annoying simultaneously), but I think for best results you need two antennas that are very close in design. You should have plenty of room up thar in the hills for that! I would add to the initial post that, the reason I think two similar antennas would be better is because you really want each of them to "hear" the same noise at roughly the same level and the same way. The ability to null that noise is optimized when the noise signals are about the same strength. Having said this, it is best also to have the antennas separated by a fraction of wavelength of interest, which is usually not a problem for most people. Right now, I am using a DXUltra sloped multiband Dipole and a 45' random wire; these two are fairly effective together, but I think that two dipoles or two similar random wires would be even better - based on my limited experience, I think I could get some really deep, quiet nulls on pretty nasty noise with that setup. I just wish I only had one noise source! BJ |

I plan on using a 15 Foot Vertical 'Snake' Antenna made out of a single piece of Coax Cable for the Noise {Sense} Antenna with the Noise Cancelling Combiner/Phaser.

FWIW - I understand that the MFJ-1025 without the little built-in Whip {Noise} Antenna is preferred over the MFJ-1025 that has the little built-in Whip {Noise} Antenna. ~ RHF *.- Hide quoted text - - Show quoted text - - If you remove the whip and configure the internal shunts - appropriately, the 1026 effectively becomes the 1025. * - Interestingly, that little whip works quite well if no other - antenna is available. - - Bruce Jensen - BpnJ - Do you have either -or- Used Either ? ~ RHF Also, regarding that little whip - when I first got the device before putting up antenna No. 2, I used the whip quite a bit, and it amazingly did a pretty good job on 60 and 75 and 90 meters, which are real problem bands for me. If noise nulling is all you are interested in, rather than actually phasing antennas, then all you need for the accessory antenna is something that will "hear" the noise, and that little whip did fine job, at least here. It also heard the stations pretty well, given that it has a fairly strong preamp behind it :-) I never tried the whip as a MW station nuller. BJ |
