    In the 'good olde days' (pre-402CD), the most widely used 40M antenna by 
competitive stations was the KLM 4L. For some reason it had interaction 
problems which were solved by many stations by turning it 90 degrees from the 
tribanders.

    The CC 402CD (and other shorty forties) never exhibited this problem and 
it was unnecessary to turn it out-of-line with other antennas. My experience 
with the XM240 is that turning it 90 degrees made the problem worse.
