Between 1985 and 1993 I used to be active with my caravan on a portable location for almost all V-U-SHF contests. Sometimes as a single operator and often as multioperator. One of our favorite locations was JM19NW, near the Northest point of Mallorca.

The antennas: 17 el. for 144 MHz, 21 el. for 432 MHz & 55 el. for 1296 MHz.
