PROMHD11L

Fully-screened amplifier modules in robust diecast enclosures. Strong cast-in 'F' connectors.
Free-draining moulded outer enclosures give easy access and cannot trap water.

Variable gain models have interstage control to maintain good noise figure at reduced gain.
All multi-way amplifiers can be powered via any output.
Also available complete with power supply (proPSU11F).
With equipotential bonding point.
