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.
