Six Way Antenna Relay Box
This product is temporarily out of stock. Please check back for availability.
The Six Way box is designed to connect one input to any one of six outputs. It is useful for antenna selection, filter or stub selection and stack switching. It may be driven directly by a Band Decoder or any selector scheme which grounds one or more of the control lines. All unused outputs are grounded.
The Six Way Relay Box uses 12 Vdc relays mounted on a stripline printed circuit board which, combined with short leads to the SO-239 connectors, provides excellent RF performance. One of our customers, Peter, VE3PN, measured the performance of a Six Way Relay Box that he purchased, and provided the following plots of isolation and insertion loss versus frequency. This independent test verifies the ratings given below. The files are in Adobe Acrobat .PDF format, and are about 200K each. Double click on the title to download the file.
