Although UHF 225-400 MHz operation can provide relatively low-cost satellite communications, the exclusive frequency allocations necessary for very simple systems almost certainly cannot be obtained. In this note a scheme is described which alleviates this problem, allowing co-existence between the current line-of-sight users of the UHF band and potential satellite users equipped with relatively inexpensive terminals.
