Don’t forget your factor 30
But have done beach dx-ing before myself.
Best time to visit the beach is when a high tide is due 1 hr prior and afterwards and higher the tide the better. And make sure you have a good CP wire running to the water helps also.
Many many moons ago we used to have Honda 90 bikes with CB’s and we visit the sea wall on East coast UK during high tide periods and what you could hear and work during that 2hr period of high tide is unreal compared to out side the zone. One day it was a well high spring tide and we were not just getting up and down the coast line of the East and south UK also working into German, Dutch and French Coastal stations. Me on 4 watts and me 1/2w fire stick and me mate with 40w and his 5/8w fire stick he even clocked north Portuguese station now this on 27mhz FM. But then we spotted a chap little further down with his 2m portable and he had heard what we did and tried it out him self even he was amazed on where he was reaching during the 2hr period and after that last hour all dropped out bah local stations.
Tell you if you going down the coast make sure the high tide is in and its above 5m pack higher the better.
Then that led to this with 3 El beam and Antron 99 again awaiting the high tide many many moons ago. Yet to experiment on the lower bands below 10m. But one day want to get back to dong the tidal thing again with Ham radio, and me verticals
