I’d challenge the restriction. I doubt that everything in the house is “UL listed”.

That said, the fear and concern is real. It’s why many such products run on 5 or 12 volts.

I’d also check if you are actually switching mains power, rather than sending a separate control signal to the WLED.

UL listed?

I don’t know what your specific antenna looks like.

Generally you connect close to the centre of the antenna, where the two elements are closest together, again without touching each other.

That said, there are antenna designs where this is not true.

Give us a link instead. That said, read on.

In general, antennas are not like a “normal” circuit where things need to connect to each other to work.

Most antennas are made of two halves or poles, hence the name, dipole.

A Yagi antenna is a dipole with separate elements to focus and reflect the radio waves. These elements are normally not connected to each other.

In a typical Yagi only one pair, the dipole, is the driven element. The many (shorter) elements are directors, the one (or two) behind the driven element is the reflector.

A coaxial cable has two conductive elements, the core (the middle bit of metal) and the shield (the outer braid). These should normally not connect to each other.

You connect each coax conductor to its own dipole element. It generally doesn’t matter which coax conductor connects to which dipole element.
