Hello Peter, A very small footprint Antenna: I use a 8m fishing pole, 6,2m wire vertical mountet, a small homemade L/C Tuner. 3 Meter rg174 a Choke near the trx. The counterpois is the koaxcable. Works well from 10- 20 Meters. No radial. Vy 72, Edwin DK2TY

Hi,I use aground spike and camellion 17ft extendable whip with just one radial with a weight on it thrown into the sea,works fantastic :)

I typically use a mag loop because beaches are very busy.

Peter, I'm surprised you omitted a key importance - EMR safety. At a crowded beach, you have no control over how close people sit, you accept the risk TX'ing cm's from your body, you're in a controlled " professional" zone, but mr and mrs smith and little johnny and jeanette smith and other families to your immediate personal space are likely unaware of EMR risks, and therefore are in the uncontrolled "public space" zone, which is even at 10watts on 10mtrs is about 1.2metres distance, and 5watts about 90cm, yet they will at a packed beach be within the "controlled" zone (certainly at packed Qld and NSW beaches) So I think you need to include the safety aspect in your operating conditions, of course 10w on 40m is safe unless you let then lean on your antenna, and even 20m is likely going to be ok with a min dist of 63cm. Lets not forget, many will be operating a darn sight higher power, even if they claim 5 or 10w, we all know it happens. But I still liked the video and your suggestions

If it was that packed then I don't think you'd even set up a station. Plenty of opportunities to go earlier or later and DX conditions may well be better on bands like 14 & 18 MHz anyway.

For the UK, I found "EMF-2: RSGB Guidance on EMF Compliance Checking" which states, "The 2.4m separation guideline obviously cannot apply to hand-held or body-worn radios. For these and many other low power situations, Ofcom allows compliance to be demonstrated a different way, by showing that the time-averaged EIRP is less than 10W (and also that the peak EIRP is less than 100W). If you can show that, then no further assessment is required - but you still have to calculate the EIRP and record that fact." So, if you have a QRP rig like FT-817 where the spec. is 5W output and the gain of your antenna is no greater than a dipole (around 2.15dB), can you argue that you fall within the 10W EIRP limit? Of course, reasonable precautions to make sure public don't come into contact with RF conductors would still apply.

EMR safety, another big con like climate change.

A highly overrated problem. There would be more EMR from power lines or a mobile phone.
