Simple way to set up an amateur radio station on a beach

I finally get chance to get to the beach in South West Wales, beautiful part of the Country.I work the 20m band using a Xiegu X108G radio, MFJ portable tuner and a brick of a battery. The antenna was a homebrew 1/4 wave vertical wire with around 15 to 20m of radials. The antenna was simply a wire cut for slightly longer than a quarter wave, helical wound around a 4.1m flag pole with the remaining sloping down. I used a spike to sit the pole on set at an angle to make sure the sloping radiator did not get twisted and wrapped around the pole. The MFJ tuner worked perfectly, I attached the radials to the ground lug and the radiator to the long wire post.
