It’s while TO1USB activation in Guadeloupe, where I could test in real conditions the setting of a portable ham radio station that I wanted QRV on 50MHz, 28MHz, 21MHz, 14MHz, 144MHz, 432MHz only on USB mode.
Not so easy in portable on a island between compromise of easy to travel and antenna performances. For the transceiver, no problem, the ICOM 706 MKIIG is a real good rig to operate quickly on 6 bands with 100 Watts from 14Mhz to 50Mhz, small and easy to carry out.
To return to the antenna question I need to be QRV on 6 bands HF+VHF+UHF but especially be able to assembly and disassembling antenna quickly and even for a single person alone to do it.
Here is what looks like the final result and solution founded :
