The antenna comes with:
Black part (with 9 holes for plugging in the jumper cable) with silver colored body (total
mechanical length 67 cm / 26.4 in)
Long (L) top radial with a variable active length between 46.5 cm / 18.3 in and 77.5 cm / 30.5 in
Short (S) top radial with a variable active length between 25.5 cm / 10 in and 56 cm / 22 in
Silver extension radial (fixed length of 31.7 cm / 12.5 in)
Jumper cable for use with black part
2mm Allen-key (required to move the fixing part of the S and L top radial)

1. Select the listed top radial according to the frequency you plan to use.
2. Mount the top radial into the extension radial.
3. Mount the extension radial onto the black part.
4. Release the grub-screw of the fixing part (just a little turn counterclockwise) to align the length of
the top radial.
The following table shows how to set the length of the short (S) / long (L) radial:
How to setup the antenna for use of a specific band:
f [MHz] l [m] Band Jumper Which top
radial to use
Visible length of top
radial (without the
extension and without
the black part)
Total silver
radial length
(extension plus
top radial)
5. Tighten the grub screw of the fixing part (by turning the grub screw clockwise).
6. If required, plug in the patch cable accordingly. One side of the patch cable is always (except for
80m band) plugged into hole 1.
