The CHA SPIDER ASB is an octagon-shaped Antenna Spoke Base designed to allow mounting of four dipole antennas that use the standard 3/8” x 24 stud antenna base, such as the popular HamStick-style mobile whips, permitting four-band operation without band switching. Using the included Easy-Up CHA UMB-U-Bolt Base, the CHA Antenna Spoke Base Series attaches to antenna masts up to 1 3/4” in diameter.
Almost any pair of your High Frequency (HF) and 6 meter mobile antennas (like the popular HamStick-style mobile whips) with a standard 3/8” x 24 stud mount will work with these mounts. The CHA SPIDER ASB is an innovative antenna mounting system, designed to be the most versatile, high performance, and rugged portable antenna mounting systems available.
