READ - Two Do-It-Yourself "Kits" for Ten-Tec :
RF Pre-Amplifier and Active Antenna

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
