The MVV 432-VOX
does have a built-in HF Vox, which allows automatic and reliable operation at standard power levels. For higher power levels a separate PTT keying line must be used. This can be done directly from the PTT line of the transceiver or by means of a separate sequencer. Most important for a pre-amplifier is the adequate gain at a good (high) 3. order intercept point (IP), this is necessary for a good large signal handling capability. Most amplifers have an adjustable gain level, this protects the receiver against overload while sufficiently compensating for cable losses.
The preamp shoud be located as close to the antenna as possible to keep the cable losses as low as possible.
