Stephen Dunifer recently sent out an e-mail titled “The Revolution Will Be Televised,” which said, in part:
Free Radio Berkeley’s engineering staff has managed to design and develop low power VHF and UHF transmitters by the creative use of off-the-shelf technology. So far, design engineering efforts have yielded TV transmitters capable of reaching a distance of 4-5 miles. Estimated cost for a VHF transmitter and antenna system with an effective radiated power of 75 watts is about $500, $700 to $800 for a system with an effective radiated power of 400 watts. For a UHF system, add about $300 to the above amounts. Coverage pattern is 220 degrees, not fully omni-directional. Further work is continuing on the development of antenna systems….
