Mini-Circuits is a good company, and I've specified their 4-way VHF/UHF splitters for 35 years for use with the pro wireless mic systems I design for performance and broadcast facilities. BUT -- most Mini-Circuits products are designed for use at VHF and UHF, and few are suitable for use as low as 2 MHz., The good news is that Mini-Circuits has a very good on-line and print catalog, with enough data to let you figure out whether each of their products might fit your need. In general, many VHF/UHF attenuators are built with capacitive dividers rather than resistive dividers, and are unlikely to be useable at HF and below. Conversely, simple resistive attenuators are quite suitable in the 2 MHz range, provided that they are made with resistors that are not inductive, whereas their stray L and C would render them useless at higher frequencies. 73, Jim Brown K9YC _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
