Radio Antenna Preamplifier Kit
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 circuit board to simplify construction and create a nice finished project. This preamplifier is generally used with receiving antennas (Loop, Long Wire, Beverage, etc) in the amateur radio bands (160m, 80m, 40m, etc). This preamplifier would also be 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 through hole components and avoiding surface mount construction. This classic design is based on a single 2N5109 NPN transistor. Note that the amplifier does require a 12-13 VDC power supply for operation, which is not included. We ship by 1st Class Mail in the U.S.A. International customers please use the special Paypal link which includes an additional $10 for shipping by International Postal Mail.
