2 Specifications
Congratulations on the purchase of your TW2010 antenna! The TW2010
represents a revolutionary jump in HF antenna performance, convenience, and
reliability. The ruggedly built TW2010 was designed with ease of use in mind.
Therefore, all TW2010 antennas are pre-assembled and tuned at the time of
manufacture. With its compact three-part fold-up design, the TW2010 is ready to
go right out of the box1 for permanent installation, or quick and easy travel, using
the optional Quadrapod folding travel stand.
The TW2010 is a center fed vertical dipole antenna with a very low radiation
take-off angle (around 27 degrees above horizontal), allowing for very long skips
using low power on 10, 12, 15 17, and 20 meters2. The TW2010 is a groundmounted omni directional antenna, requiring no ground radials, tower, or rotor.

4 The Components of your Antenna
There are three basic components to your new TW2010: The structure,
the controller, and cabling.
4.1 The Structure
The structure of your antenna has been built in four pieces, top,
middle, bottom, and permanent mounting assembly. The top and
bottom pieces fold up for quick and easy travel. Fold-up and
assembly of the three main structure pieces is achieved using preinstalled clamp knobs. See below for a summary of these four
components.

4.2 The Controller
Your TW2010 is supplied with a 5-band auto controller used for
band switching. The controller can be used in automatic mode or
manual mode. Automatic mode is available for use with many
modern Icom and Yaesu radios, using an optional cable,
available from Trans World Antennas.
Below are diagrams of the front and rear panels with feature
descriptions.

(1) Power switch. Use to turn your controller on and off.
(2) Auto indicator. This amber LED will light when the controller is in automatic
mode. This LED will blink when, in automatic mode for Icom transceivers, an
attempt is made to operate the antenna outside the 10m to 20m range.
(3) Band indicators. These five green LEDs are used to display which band the
antenna is currently switched to (assumes the antenna is properly connected to
the controller).
