W7IUV Radio Antenna Preamplifier Kit

Low Band Preamp Assembled

Kits are in stock and available for immediate shipment!

The RADIO ANTENNA PREAMP KIT (#PREAMP) from MTM Scientific is for building a low noise radio antenna preamplifier for the 1 to 30 MHZ frequency range. This kit is based on the classic design of W7IUV, according to these Published Plans (Courtesy of W7IUV).  The plans emphasize the importance of using specific parts, which can be expensive and time consuming to gather. The MTM kit contains the correct parts, and also includes a printed circuit board to simplify construction. This preamplifier is generally used with receiving antennas (Dipole, Loop, Long Wire, Beverage, etc) in the amateur radio bands (160m, 80m, 40m, etc). This preamplifier is also useful for regular commercial shortwave radio reception. Special thanks to W7IUV for making these plans available to the Amateur Radio Community. We have made this kit assembly-friendly by using classic electronic components, no complicated surface mount. This classic design is based on a single 2N5109 NPN transistor with a large heatsink (You will receive the transistor with the heatsink already attached. See photo below). Note that the amplifier requires a ~13 VDC power supply for operation, which is not included. We ship by 1st Class Mail with tracking in the U.S.A. Sorry: No International orders at this time.  

Antenna Preamp Kit: Frequency ~ 1 to 30 MHZ, Gain ~ 20 Db, Input Impedance ~ 50 Ohms, Power Supply (Not Supplied) ~ 13 Volts DC

Please note: This is a kit requiring assembly, which includes electronic soldering and winding a small coil.  We are not able to offer a refund after kit assembly begins. Important: A customer wrote to us with RF test results to advise that IMD is an issue with those foreign-sourced "Motorola" transistors. We do NOT use those transistors in our kits!
