Vectronics VEC-1444K KIT, 440 MHZ, PRE-AMPLIFIER
KIT, 440 MHZ, PRE-AMPLIFIER
Soup-up your antenna system and "pull the weak ones" with this easy-to-build LNA (low noise amplifier). Here's a high -gain, low-noise preamp that will work wonders for your scanner or ham-band receiver. Unlike low-cost GaAsFET preamp's, Vectronic's kits use a high quality microwave type bipolar device for exceptional low-noise performance and immunity from damaging electrostatic discharge. A high-Q LC tuned input filter fights overload from out-of-band signals, and careful output matching ensures efficient energy transfer into your 50-Ohm feedline. Will cover near-by out-of-band commercial channels with only minor retuning.
