3.5 MHz pedestrian mobile with the Wadetenna https://stream.echo6.co/videos/watch/eef418a9-9829-4e65-a0f5-43e97efcaadf Experiments with 3.5 MHz pedestrian mobile with a 5 metre centre loaded vertical in the water. Stations worked were up to approximately 150km distance. The time was 8am. Interestingly the effect of touching the sand was less marked than on 40m. Use this to calculate the inductance required for centre loaded verticals: http://www.m0ukd.com/calculators/loaded-quarter-wave-antenna-inductance-calculator/ Use this to calculate the coil dimensions for the required inductance: http://www.daycounter.com/Calculators/Air-Core-Inductor-Calculator.phtml PS: If you liked this video please consider supporting Amateur Radio VK3YE by: Subscribing on YouTube,, Checking my books page at https://books.vk3ye.com, Shopping on Amazon via: https://amzn.to/3iiDQXv, or, Shopping on eBay via: https://ebay.us/i9DuWP (then if you buy something I'll get a small commission at no cost to you) Wed, 06 May 2026 01:03:02 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://stream.echo6.co 3.5 MHz pedestrian mobile with the Wadetenna https://stream.echo6.co/client/assets/images/icons/icon-512x512.png https://stream.echo6.co/videos/watch/eef418a9-9829-4e65-a0f5-43e97efcaadf All rights reserved, unless otherwise specified in the terms specified at https://stream.echo6.co/about and potential licenses granted by each content's rightholder.
