HF MULTIBAND BEAM
10 - 20 Meters
High Front To Back Ratio
On 10/15/20m
Easy To Tune
No complicated gamma
matches to adjust.
Easy To Turn
With a boom length of 7 feet
and a longest element length
of 17 feet, a lightweight TV
rotor will do the trick.
Low VSWR
Flat response across all 5 bands.
VSWR minimum 1.2:1.
Single Feed Point
Only one coaxial feed line is
necessary for all 5 bands.
MA5B. Cushcraft’s newest multiband HF antenna provides 5 band directivity in a
package small enough to mount to a tripod. The MA5B is a design that does not
sacrifice ruggedness, performance and power handling for size and ease of installation.
The ASL2010 log periodic antenna is the most cost effective, high gain, five band
antenna solution on the market today. Skylog offers continuous operation from 13.5
to 32 MHz. Antenna gain and beamwidth are constant for uniform coverage from 10
through 20 meters. The ASL2010 is rated for continuous duty at full legal power. Skylog
is designed for maximum gain on a manageable 18 foot boom with only 10.1 square
feet of wind surface area. All stainless steel hardware and rugged element design are
only some of the many features that provide years of superior antenna performance.
Skylog ASL2010 is the smart choice for multiband HF operation.
