I calculate 7.03 metres. this was done using L(ft)=468/F(MHz) this
accounts for end effect shortening. See ARRL Handbook.
This difference should not be a big factor in reception as you
attenuate external noise as much as the signal with a mismatch at 10 MHz.
Your taxes are paying for some nice propagation data collected in Oz.
Check the web site for current HF conditions
