Operation with two low-power transmitters and 35-foot antennas would result in a .limited audio service along the shore line and to the rising ground immediately. inland. The signal would be very weak and subject to interference from television stations on the adjacent channel and could be Janned with mini ma effort. b. A moderate tncrease in antenna height and a small increase in power would increase the service only a small awuznt and would not produce any significant irprovement or render Jamming particularly difficult. c. Transmission from a height of sona 5000 feet, using only moderate power (100 watts to 1 kilowatt), would result in a significant iaprovement in service in all areas and produce a signal requiring considerable effort to Jam. 2. As these conclusions suggest, transmissions from an airplane vould be the eost effective, while transmissions from. the surface with antennas of up to 35 feet have linited effectiveneso. Nevertheless, Reference and other debriefings of persons caning out of Cuba have given evidence of the apparent effectiveness of the AMPEIl TV intruionm in the Havana area and indicate that they are worth continuing until some more effectivo medium is put into use.
