The band here is 137kHz not 160 kHz - that is the frequency the USA Lowfers have For some months I held the UK distance records for both 73kHz and 137 kHz using a Marconi tee antenna just 7m high with a top span of three wires of 15m. (I think these are roughly equivalent to those American or olde-English 'feet' units of measure you refer to). This size of antenna, fed with 200 Watts or so is more than capable of working up and down the country unless noise levels are particularly high. If you use narrowband techniques there is no reason why European contacts won't be possible Andy G4JNT
