Have a MFJ-1026 noise canceling signal enhancer and have determined that the
only way it can really achieve the desired results in most cases is with a remote antenna. I use a 40 meter double extended center feed zepp on 80 and 40 meters with great results. Recent birdies (Noise) from a man made product which I can not track down gives me S-9+ signals on 80 meters and around S-7 on 40 every 17 kc's. I have read were some success using a 20 meter dipole has provide a strong enough signal for the MFJ to be effective. I am thinking of using a 40 meter dipole 40 feet lower than the Zepp and around 40 feet parallel to the Zepp. That large of a antenna however might induce to much RF on the Aux antenna connected to the MFJ and cause future problems. Looking for recommendations from users of the ANC-4 or MFJ-1025 or 1026. Your input will be appreciated, thanks in advance. 73 - Ron W4LDE |

Put up a long wire INSIDE as your sense antenna. Do NOT use an antenna that is well coupled to the transmitting antenna! It is not easy to properly adjust the MFJ, but with a careful tuning, you can null out the "birdies". Be sure to write down the settings for the frequencies you,,, frequent. 73 - Ron W4LDE -- * | __O Thomas C.
