The UBS-6 (RA22-02XX-XX) is a wideband 6 hole universal antenna base designed for use on mobile platforms and features the 6 hole NATO mounting pattern.
Suitable for use with HF, VHF and UHF antennas, the UBS-6 is a logistical problem solver in that it provides a common, universal mounting for most antennas.
The antenna mounting spigot is a universal 50 Ω co-axial coupling, designed to accommodate a wide variety of antennas, of different configurations and frequency ranges. (e.g. VCF30-108, VCF115-175, VCF225-420, VCF115-420).
