Greetings Yodar! I forgot to mention that I also have the Ten Tec
active antenna and for me it does not work quite as well as the Radio Shack version. I have seen the Ramsey kit online but have not really studied it. Part of what I am wondering about is what are the advantages of having an outdoor active antenna verses an indoor active antenna. Thanks for the suggestion! Have a great week!

JON,
READ - Two Do-It-Yourself "Kits" for Ten-Tec : RF Pre-Amplifier and Active Antenna http://groups.google.com/group/rec.r...8c5523e79b8e0a http://groups.yahoo.com/group/Shortw...a/message/5920 Take your TenTec Active Antenna and mount it on the Free-Standing "Grounded" Metal Mast {Top-Rail} as described in the prior post. Use a CB (10m) Whip Antenna for the Antenna Element. Ensure that you have a Ground Rod built into the Concrete Anchor of the Top-Rail and that the Mast is Grounded. Place a Snap-On Ferrite Core (Bead) within an Inch or two of both {each} Ends of the Coax Cable Feed-in-Line between the Actve Antenna and the Radio. FWIW - Using the Free-Standing "Grounded" Metal Mast {Top-Rail} is a good idea for 'mounting' small Vertical Antennas. 1 - Elevates the Antenna away from the RFI/EMF envelope of your House. 2 - Grounds the Active Antenna Module and Coax Cable Feed-in-Line. 3 - Run the Coax Cable along the ground; or better yet Bury the Coax Cable under-the-ground as much as possible. TIP - Ensure that the Free-Standing "Grounded" Metal Mast {Top-Rail} is located at least 20 Feet from the House and other structures to also get it away from the RFI/EMF envelope of your House. DISTANCE AWAY - Out-and-Away and Up-and-Away are both Important to Reducing the 'relative' Noise that your small Vertical Active Antenna must exist in to pick-up and receive signals. Placing the Antenna Element Out-Side the House's RFI/EMF Envelope {Physical Distance} is one of the simplist and most effective techniques in creating any Low Noise Antenna. IMHO - You should here a lot less noise and better quality signals with this Out-Side small Vertical Active Antenna set-up then with the RadioShack {InDoor} Active Antenna. hope this helps - iane ~ RHF |
