Among recent AM antenna systems to use the new LBA VC-1 Vacuum RF Relay is a seven tower 50 KW directional at KYES in St. Cloud, Minnesota. KYES is a new Catholic community talk radio service of The Throw Fire Project.

In addition to two phasor cabinets, the complex system includes two open panel ATU’s and five weatherproof cabinet ATU’s. The use of LBA VC-1 master and slave vacuum RF contactors has permitted more compact and logical layout of the phasing equipment without sacrifice of serviceability.

The military-grade vacuum RF switch elements are rated for over 500 years of trouble free operation! Traditional contactors are lucky to operate for a few years without repair and maintenance.

Shown here is John George, VP of Sales for LBA Technology with a KYES 50,000 watt antenna tuning unit. The uncluttered appearance of the RF switching elements is clearly seen. John says that there is one thing missing – no more earth shaking bang of RF contactors operating. The LBA VC-1 RF contactors are totally silent!
