With the evolution of wireless, broadband, IEEE 802.11a,b,g Wi-Fi, WLAN, and new telecomm solutions, the need for new coaxial interfaces has spurred the development of MCX, MMCX, SMB, 7-16 DIN, reverse polarity SMA and reverse polarity TNC Unidapt® Adapters. They join the BNC, TNC, N, SMA, UHF, and mini-UHF adapters already in the product line. All adapters are made of silver plated machined brass with gold plated contacts and Teflon insulation. The RFA-4019 is designed as an expansion kit for those already owning Unidapt® system. It contains 27 pieces of the new adapters listed above in a foam-lined case large enough to accommodate the full line of Unidapt® products.
