= = = ... I personally used the MFJ-1024, for four years, when I lived in a townhome. Rules of the Homeowners Association, left me with little choice back then. I have to admit, it worked fairly well, and it was quieter than I expected. I opened up the remote box, in order to solder a longer length of coax for my installation. All the components in the remote box are coated, to protect them from moisture. I would however recommend using Coax Seal on each section joint of the telescopic whip antenna, because it will get a water build-up, inside the sections. Good DXing to you, Gary KACHINA78, Two Suggestions concerning Replacements for the Small [Collapsable] Whip Antenna on most Out-Side Active Antennas. http://groups.yahoo.com/group/Shortw...a/message/1752 1. For "Out-Side" Use. I would suggest replacing the Collapsable "Whip" Antenna with a short jumper to a 104" CB type Stainless Steel {Solid-On-Piece] Whip Antenna if used OutSide. TBL: The result will be a Larger Signal Capture Area due to the 'longer' single Vertical Whip Antenna Element with NO Mechanical (Telescoping) Joints. 2. For "In-the-Attic" Use, I would suggest replacing the Collapsable "Whip" Antenna with a Screw/Bolt and Washer -or- a Nut and Washer mounting. - Use a Copper or Brass Washer. - Cut Two #12-#20 AWG Insulated Stranded Copper Wires to Twelve Foot {Equal} Lengths. - Solder the End of the Two Wires to the Copper Washer. - Attach and Secure the Washer to the Active Antenna Head Unit where the Whip Antenna would be mounted. - Spread the Two Copper Wires 'out-and-up' from the Active Antenna Head Unit at 90 Degrees: - - One N & S - - The 'other' E & W. - - They should form Diamonds (Squares standing on a Corner) Three Feet Sides with a Height of Six to Four Feet; and a Width of Four to Six Feet. - - Suspend the Top-Point-Corner using a Nylon Mason String from the Peak of the Roof; and use Nylon Mason String to spread the Two-Side-Corners out to about Four Feet but NOT more than Six Feet; the Weight of the Active Antenna Head Unit will usually 'hold' the Bottom-Point-Corner in place. TBL: The result will be a Larger Signal Capture Area and lower Noise due to the Two Diamond 'shaped' Wire Antenna Elements; vice the single thin Vertical Whip Antenna Element. iane ~ RHF ..
