25-30 Watt UHF Broadband Amplifier Kit

This kit includes all components and instructions to build a very easy to assemble amplifier that uses broadband power modules. The amplifier is driven directly by the cable TV modulators listed under the TV Transmitter Kits and the TV Broadcast Transmitter sections. Broadcast on channels 14 through 30 can be achieved with this amp. Even though the power levels are not high (30 watts), given the proper combination of antennas and amplifier, very respectable effective radiated power can be achieved. For example: two amplifiers can be driven with the same modulator by using a signal splitter; the output of each amplifier is fed to its own two element antenna, one stacked above the other; the two element antenna has a gain of 4.5 dB, stacked together the total gain is 9 dB; with a total gain of 9 dB and a total input power of 50 watts, the effective radiated power is about 400 watts! Please contact for international shipping costs. An extruded aluminum enclosure with integral heatsink as shown in the photo is available for an additional $75.
