Some of the features of my set up

A finger trap style coaxial strain relief at the antenna. This uses synthetic rope which is pulled apart and then re-woven around the coax, so the weight of the coax doesn’t pull on the connections at the bottom of the antenna.

Homemade lugs for connecting the coax to the Internet. These are just made out of a little piece of copper, drill a hole for the bolt and fold over the corners for soldering and for strain relief. Much less expensive than buying them, and I can always get them in the size that I need with short notice

The main vertical element is the driven element from a small Yagi which uses traps to get the tri-band low SWR . For 10 m for example the trap separates the upper section from the lower section, so the lower section resonates at 10 m and the upper section doesn’t do anything. The trap basically has no conduction only at 10 m and good conduction on other bands.

Another idea was to operate from cw from noon to 1, this is the “slow speed test “. There are US and DX stations on there, and lots of people so that it’s fun to make a bunch of contacts quickly

I think it is a good decision to avoid the strong heat in the hottest part of the day! I guess there’s no zoom also.
