It doesn't stop you from getting a dipole (or other antenna) ready provided you only use an impedance bridge to tune it. Just no transmitters allowed - yet !!!
We already know what the centre frequency will be because of " the word-wide allocation of 5351.5 to 5366.5 kHz to the Amateur Service on a secondary basis " gives 5360KHz to tune to but the SWR bandwidth / tuning will be fairly broad so that an approximation is all that is required.
I plan to add a 60M section to my multiband 80 / 40 /30 dipole set as that will be fairly simple. I suspect I would run into tuning issues if I added it to my 160 / 80 / 40 /30 dipole set due to ' near' 1 and 1/2 wavelength actions from the full-size 160 metres section (CF=1830, 3x = 5490) - then again it may already give a reasonable SWR at 5360 but I can't try it. Maybe the 130KHz shift will be too far to be an issue in terms of tuning interaction.
Must have a listen across that band occasionally and see what I can hear internationally ....
